ERC RECOMMENDATION 70-03
Dear Experts, As per this ERC recommendation relating to the use of SRDs, devices falling under the Annexure 9 Band F1 category, are 'Not implemented' in many of the European countries. What does this mean? What if the emission level is more than 42 dBuA/m at 10m but less than 60 dBuA/m at 10m in the specified band? For my device it is about 53 dBuA/m at 10 m and it cannot be reduced also? Does it mean 'licensing' will be required for my device? I request you experts to help me in this regard.

Harmonics and flicker
All Is it necessary to show compliance with harmonics and flicker requirements for products even though the product standard applied specifically omits this?. My concern is that EN61326 requires these measurements for Class B equipment but specifically does not for Class A equipment.

RE: Type of fuse in Schaffner power module inlet FN280
Amund - Assuming your concern is provision of spares or fuse replacement in the field, so long as your company stays within the appropriate ratings for the overall device, it should not be a great concern for your product to be marked with a fuse replacement marking indicating the fuse type and rating your company specifies. There should be some markings on the fuse ferules to guide you. Regards, Peter L.

This is a multi-part message in MIME format. Pat, Some years ago there was rumor that HP (Agilent) was getting out of the EMC Analyzer business entirely. Later on, they recanted.

Northeast Product Safety Society Meeting Next Wednesday, October 26th
All, There will be a sequential or joint Northeast Product Safety Society and EMC Society meeting next Wednesday, October 26, at EMC Corporation's Conference Room 1-2 (Building A, 1st floor) at 228 South Street in Hopkinton, MA. A social hour with light refreshments will begin at 6:00 PM and the technical meeting will start at 7:00 PM. Our first speaker will be Douglas Smith, of D. C. Smith Consultants, presenting an EMC related topic concerning methods of locating impulsive events such as ESD in 3D space. Our second speaker will be Stanley Salot Jr., Business Development Director of NSAI in Fremont CA, presenting a product safety related topic concerning the EU WEEE and RoHS directives from the perspective of one of the world’s first WEEE registrars. If you will be in the area, please feel free to join us as advanced notice or membership in NPSS or IEEE EMCSS or PSES is not required. Doug Smith is an independent consultant specializing in high frequency measurements, circuit/system design and verification, switching power supply noise and specifications, EMC, and immunity to transient noise. He is a Senior Member of the IEEE and a former member of the IEEE EMC Society Board of Directors and an IEEE EMC Society Distinguished Lecturer. He retired from ATT Bell Laboratories a Distinguished Member of Technical Staff and has been granted over 15 patents, several on measurement apparatus. He is author of the book High Frequency Measurements and Noise in Electronic Circuits. His very popular website, http://emcesd.com -- www.dsmith.org, draws many thousands of visitors each month to see over 60 technical articles as well as other features Doug’s presentation, “Locating Impulsive Events in 3D Space Using Time of Arrival Techniques”, concerns impulsive events, such as ESD, which can cause problems in the lab as well as the field ranging from noise glitches in measurements to outright equipment malfunction. This talk will present a procedure for finding such events using just an oscilloscope, a pair of coax cables, and two short wires. Using this technique, events that were causing problems have been pinpointed from over 50 feet away! Audience participation will be used for one of the experiments to make for a fun talk. Stanley Salot is Director of US Western Region Business Development for the National Standards Authority of Ireland (NSAI, Inc.). As director he is responsible for the development and coordination of new and continuing business opportunities, in the ISO 9000, QS 9000, ISO 13485, ISO 14001 Standards and CE Marking for European shipped products. As a Lead Assessor, he developed, coordinated and participated in workshops, pre-assessments, registration assessments and surveillance inspections throughout the USA and Internationally. Stan has served as Chairman of the Users Advisory Group for the International Electronic Component Certification Board (ECCB). He is an active member of the American Society for Quality (ASQ) and co-founded the Santa Clara Valley Software Quality Association (SSQA). Stan’s presentation “IECQ HSPM Certification Is Your Route To Compliance!” will describe and define the QC 08 HSPM standard and explain how it is applicable to demonstrating compliance to RoHS, WEEE, CA-SB 50, China Article 11 12 and others. This standard and its requirements are based on the belief that the achievement of Hazardous Substance Free (HSF) products and production processes cannot be realized without an effective integration of management disciplines. Further information on our speakers and their presentations will soon be available on the NPSS web site at http://www.nepss.org. If you or anyone you know would like to give a product safety technical presentation, please contact Paul Smith, our meeting scheduler, by email at pauljsmi...@cs.com. A technical presentation should be 45 to 60 minutes in duration and be related to product safety. Although the presentation may reference your company and it’s services, the presentation must not be simply company advertising. We would also appreciate any slides or handout materials be made available for posting on the NPSS web site. Releasing presentation materials for posting is desired but not a requirement to make a presentation. The 2005 NPSS meeting schedule is available on the NPSS website at http://www.nepss.org/meetings/NPSS_2005_Calendar.html. Further information about the Northeast Product Safety Society and how to become a member is available at http://www.nepss.org. You can also contact one of the NPSS officers via links on the NPSS web site. Directions: From Route 495 North or South take exit 21B to West Main Street.

RE: ESD test.
Dear Sudhakar I had a general sense that this test simulated an office environment, simulating roughly the effect that a capacitively charged person touching a table top with IT resting on the table top. I always figured there was a slight EMP effect during the test because I could always see the effect on the video and had a couple of older monitors that were more susceptible to the ESD cycle. One of my monitors quietly checked out (no video) because I let a corner of the cable traverse the Horizontal Plane (my guess). It worked afterwards but thats what I think the test simulates and I hope I’m close because I did a lot of ESDs. My advice is to design from the failure material. I don’t do memory cards but it doesn’t seem logical to test a card itself on an HCP. But then, I don’t know your test set up.

RE: EMF testing multiple radios
If the composite device can radiate all transmitters simultaneously, I believe you will find that they will need to be tested simultaneously. The exposure limit standards indicate the sum of all exposure sources, though I am not sure that you will find that the measurement methodology for a particular phantom is set up for simultaneous measurements. You'll need to work this through with your lab of choice. A fall back position might be to measure each separately and then numerically sum the results per the calling standards.

I have had this discussion with others before and it seems that each of us had slightly different experiences. One company says I, O, Q, X are excluded from use to avoid confusion with hand written numbers and symbols. Mil Std 490 says: I, O, Z, which can be confused with numerals, shall not be used. on occasion, I have seen the letter L excluded mainly because of the old manual typewriters using low case L for numeral 1 Also, should revision letters always be upper case? The subject of double-letter revisions after using the last single-letter revision has been confused by some and I have occasionally seen a sequence like the following: AA, BB, CC, DD, etc. Obviously this is not as efficient as: AA, AB, AC AD, ..., BA, BB, BC, BD, ..., CA, CB, CC, CD, ..., etc. Any comments or experiences are welcome. -Doug Doug Powell, Staff Engineer Corporate Compliance Dept.

RTTE Labelling Question
Greetings, I thought I knew this RTTE labelling stuff cold but clearly I don't :( Until the recent addition of additional countries to the EU we had clear requirements for our short range devices at 433.92 MHz According to the list kept at ero.dk our equipment was Class1 Sub Class 20. Easy label, no problem! Now with the addition of Poland (who does not accept SRDs at 433.92 MHz ) I have become confused. Does this mean that Poland, by refusing this particular use of frequency, can essentially override a commission decision determining the Class of our product? Should our product now be labelled Class 2 with the CE ! mark and a crossed out PL Or should we still indicate Class 1.20 and CE but no ! and also indicate no PL Thoughts?

RE: EMC testing for BSMI marking
Given that BSMI, CCC, VCCI and others use essentially the same standards for measurements, processes, equipment, and that test house are generally certified in a consistent manner by independent auditors (NIST authorizes A2LA, and NVLAP here in the US). One might ask themselves; why some in-country testing or the use of test laboratories that are required to pay fee's to be allowed to test are required in the first place? If it isn't the technology or personnel competency, then it must be something else, politics, trade, revenue or something. That something else almost certainly assures you that the data will not be accepted unless you play by their rules and fees, and I don't see it changing soon. I believe the issue of national accreditation with the hope of international agreement to accept the data was started around 1992 and I've just listed 3 major markets that haven't bought into the process for whatever reason. So I don't see your customer buying, and if he does BSMI won't buy it when he submits to them for acceptance. In my opinion (and maybe it's a bit jaded) if BSMI is important to you I think you stuck until you find a BSMI host. For what its worth.

Re: FCC Part 18
Paul Lovell asked I understand that Part 18 applies to ISM products but what is its current status (ie active or waived)? Is it just EMC or does it cover other things? Please excuse my ignorance, I'm new to the medical field, but I'm told there are no FCC emissions requirements for medical devices, something which surprised me given how much effort goes into complying with Part 15 in the IT field. There are various FCC restrictions on all radio frequency sources. Part 1 has limits for exposure of humans to RF, Part 2 forbids causing harmful interference to licensed services and Part 15 has limits on how much may be emitted by unlicensed devices even in the absence of interference. Part 18 is specific to ISM equipment: [ Sec. 18.101 Basis and purpose. The rules in this part, in accordance with the applicable treaties and agreements to which the United States is a party, are promulgated pursuant to section 302 of the Communications Act of 1934, as amended, vesting the Federal Communications Commission with authority to regulate industrial, scientific, and medical equipment (ISM) that emits electromagnetic energy on frequencies within the radio frequency spectrum in order to prevent harmful interference to authorized radio communication services. This part sets forth the conditions under which the equipment in question may be operated. ] At specific ISM frequencies the radiated limits are nonexistent, it being recognized that no licensed radio service will use those frequencies (but see Part 1): [ Sec. 18.305 Field strength limits. (a) ISM equipment operating on a frequency specified in Sec. 18.301 is permitted unlimited radiated energy in the band specified for that frequency. (b) The field strength levels of emissions which lie outside the bands specified in Sec. 18.301, unless otherwise indicated, shall not exceed the following: ... ] Do note that complying with a limit does NOT relieve one from the obligation to mitigate harmful interference. Part 18 may be viewed at http://www.access.gpo.gov/nara/cfr/waisidx_00/47cfr18_00.html Part 1 includes limits for human exposure to RF. [ Sec. 1.1310 Radiofrequency radiation exposure limits. The criteria listed in table 1 shall be used to evaluate the environmental impact of human exposure to radiofrequency (RF) radiation as specified in Sec. 1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of Sec. 2.1093 of this chapter. Further information on evaluating compliance with these limits can be found in the FCC's OST/OET Bulletin Number 65, ``Evaluating Compliance with FCC-Specified Guidelines for Human Exposure to Radiofrequency Radiation.'' ] http://www.access.gpo.gov/nara/cfr/waisidx_00/47cfr1_00.html FCC Bulletin OET-65 discusses human RF exposure limits: [ ..all transmitting facilities and devices regulated by this Commission that are the subject of an FCC decision or action (e.g., grant of an application or response to a petition or inquiry) are expected to comply with the appropriate RF radiation exposure guidelines, or, if not, to file an Environmental Assessment (EA) for review under our NEPA procedures, if such is required. ... ] http://www.fcc.gov/Bureaus/Engineering_Technology/Documents/bulletins/oet65 /oet65.pdf I hope this is of some help.

There is a diagram in the edition we have (1996) showing which areas of the bedframe are thus included. My interpretation is then that the bedframe should be considered an AP and so, as Doug says, it should be tested for Patient Leakage. If it were not an AP it would have to be tested for Enclosure Leakage anyhow - in both cases the limits for ac leakage are 0.1mA Normal Condition and 0.5mA Single Fault Condition (though for Patient Leakage there are dc limits too). If you are measuring 0.1mA leakage through the specified measuring device, which simulates a patient impedance, then how low the voltage is on the earthed frame is kind of immaterial - it is the current not the voltage that the patient will feel. (The leakage likely has high impedance origins which are better modelled as a current source than a voltage source).

Re: 60601-1 and patient leakage current
Doug, Have you checked out IEC 60601-2-38, Particular Requirements for the Safety of Electrically Operated Hospital Beds. This standard may clarify how you measure earth leakage current and patient leakage current for a hospital bed. (I don't have a copy of this standard, so I'm guessing). IEC 60601-1, in Table IV note 3, does allow less stringent limits for earth leakage current when the protective earth is permanently connected. However it's not clear to me how to measure patient leakage current for a hospital bed, if at all, and the answer to this is likely to be in IEC 60601-2-38. You say The measured leakage current from the power supply exceeds the patient leakage requirements (0.1mA). It's not clear to me exactly from what point you are measuring leakage current, and whether that current is to be considered patient leakage current, or even whether the leakage current you are measuring is required to be measured by the standard.

RE: 60601-1 and patient leakage current
Doug, 60601-1 is not the easiest standard to interpret, but I think that in this instance you are interpreting it incorrectly. Patient leakage current is that current which flows between an Applied Part and Earth via the patient. The accessible parts of the frame are not considered as Applied Parts. It is acceptable for protection of the patient from electric shock risk arising from contact with an accessible part to be provided by earthing. As you rightly point out, the potential of the accessible part when the earth impedance is low will be negligible. You must consider single fault conditions, so it would be wise to include interruption of the earth conductor in this case. However, perhaps you could have one earth connection via the power cord and one separate connection to a permanent earth conductor, thus providing a redundant protective earth. This is my opinion only, and I stand to be corrected by anybody more familiar with this standard than I. Best regards Neil R.

RE: 60601-1 and patient leakage current
Doug, Altho I am not completely familiar with 60601-1 since I haven't worked with it for a number of years, I will comment on leakage current requirements for earthed equipment in general. By and large it is recognized that earth/ground is unreliable for cord connected equipment around the world. (I know that US medical facilities work harder than most to provide a proper earth, but that doesn't negate the comment). For this reason safety standards specify a leakage current (Touch Current) limit for the normal, earthed case - 0.1mA as you have mentioned for your case. So, for this product - when the earth is not present - the patient will not get more than the 0.1mA allowed. I would be surprised if there were an exception in 60601 to allow anything higher than this. You could, of course, provide for a permanent, hard wired electrical connection for the equipment which will provide a permanent, secure earth/ground. Conversely you could provide an isolating transformer for the product which would isolate the product from ground so that there would be no leakage current to ground other than the leakage current from the transformer (a good double insulated one). I'm sure that neither of these seems attractive. Surely you can get a proper motor with low leakage current for this application, :) br, Pete Peter E Perkins, PE Principal Product Safety Engineer PO Box 23427 Tigard, ORe 97281-3427 503/452-1201 fone/fax p.perk...@ieee.org - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.Website: http://www.ieee-pses.org/ To post a message to the list, send your e-mail to emc-p...@ieee.org Instructions: http://listserv.ieee.org/listserv/request/user-guide.html List rules: http://www.ieee-pses.org/listrules.html For help, send mail to the list administrators: Scott Douglas emcp...@ptcnh.net Mike Cantwell mcantw...@ieee.org For policy questions, send mail to: Jim Bacher: j.bac...@ieee.org David Heald:emc-p...@daveheald.com All emc-pstc postings are archived and searchable on the web at: http://www.ieeecommunities.org/emc-pstc

Re: Conducted emission testing for FCC CE.
Ken Javor wrote Between several hundred microfarads of storage capacity and the EMI filter, that doesn't seem terribly likely but it can't be completely discounted so it makes sense as a rationale. I'm thinking a USB device is not likely to generate signals a LISN would see. On top of that, the level of CM USB-device-generated noise would depend at the LISN on the capacitance of the USB device and its cable, which is pretty low. I'd also not want to attribute to a peripheral EUT an emission the *host produces* when (and only when) an EUT device is plugged in; it doesn't take too many design mistakes for a host to make a decent peripheral look like a shouter.

RE: Conducted emission testing for FCC CE.
I would suggest that you do need to test at both supply voltages; but more significantly, your greatest problem is unlikely to be your product but the host PC. You need to select your host PC very carefully to ensure that it is compliant, and that it is quiet enough for you to be able to tell whether or not your device is contributing to the emissions.

Re: Conducted emission testing for FCC CE.
No answer here, I'm just trying to get educated on the premise behind the original question. The modification prompting the requirement for conducted emission testing is the addition a USB device powered from the PC USB host. I assume this device consumes on the order of 1 Watt of power. The incremental increase in load on the power supply is therefore on the order of 1%. The dB increase in power supply differential mode conduced emissions is therefore 10*log (1.01) = 0.04 dB This is well within the uncertainty range. Are my assumptions incorrect or what crucial information am I missing that drives the need for requalifying ac mains conducted emissions? I (perhaps naively) thought that this modification would have required a radiated emissions rescan because of the new USB interface and cable, or perhaps conducted emissions testing on the USB cable utilizing an absorbing clamp. It is not at all obvious to me how the addition of the USB interface necessitates a mains conducted emission test. From: Robert A.

Mixing of Power phases - Legal position
Dear all, This is a question aimed at the UK market - although any continental input appreciated. We have a customer who wishes to power our product via two 30A Single Phase spurs, the customer has two Power Distribution Units (PDU's) each with 3 phase supplies. The customer wishes to provide a single phase from each PDU to ensure power balancing and outage protection, but it seems cannot guarantee that we will get the same phase colour from each PDU. Brushing to one side for a moment the technical issues, and the possible frightening consequences; what does the IEE Regs have to say about such a scenario ? I have a condensed version which make no mention as far as I can tell about this kind of situation, clearly we will be demanding that our cabinets are clearly marked and the cable presentation reflects the final power installation to reduce the possibility of accidents during servicing.

RE: Test Standard
John Woodgate wrote: It isn't strictly correct to say that standards are 'under' Directives, and it can be quite misleading. That is a very important point and I suspect one which is generally understood. In particular, it seems to me that meeting the safety objectives of the LVD is the key point, not necessarily which standards are applied.

Northeast Product Safety Society Meeting on next Wednesday, September 28th
All, Note: Speaker change for NPSS meeting. There will be a sequential or joint Northeast Product Safety Society and EMC Society meeting next Wednesday, September 28, at EMC Corporation's Conference Room 1-2 (Building A, 1st floor) at 228 South Street in Hopkinton, MA. A social hour with light refreshments will begin at 6:00 PM and the technical meeting will start at 7:00 PM. Our first speaker will be Lee Hill, of SILENT, Amherst NH, presenting an EMC related topic concerning a low cost measurement system and techniques to characterize RF devices. Our second speaker will be Gregor Dzialas, of TUV Rheinland, Boxborough MA, presenting a product safety related topic concerning the FDA's Inspection by Accredited Person Program. If you will be in the area, please feel free to join us as NPSS membership or advanced notice is not required. Note: The previously announced open forum sessions will be rescheduled to a future date. Please email any comments or suggestions you may have regarding the rescheduled topics or any similar topics you would like to be discussed at an open forum meeting. Lee Hill is Founding Partner of Silent, an independent consulting firm that specializes in EMC and RF design, troubleshooting and training. Previously Lee was Principal EMC and Systems Engineer at Digital Equipment Corporation’s Workstation Systems Engineering Group in Palo Alto, California. Lee received his Master of Science Degree in Electrical Engineering Electromagnetics University of Missouri-Rolla, and has eighteen years of experience in the EMC design and retrofit of complex electronic systems. Lee is presently a member of the IEEE EMC Society Board of Directors (2005-2007), Chairman of the IEEE EMC Society’s Distinguished Lecturer Program, and a member of Technical Committee TC-10 on Signal Integrity. Many EMC engineers and technicians have and are familiar with using a spectrum analyzer with tracking generator. Lee’s presentation gives a hands-on demonstration of how to create a very sensitive, low cost measurement system for characterizing the performance of RF devices found in most EMC troubleshooting and test laboratories. Lee will use a portable test receiver/spectrum analyzer and tracking generator, together with a dual directional coupler purchased on eBay to demonstrate the usefulness of S11 “return loss” or “reflection loss” measurements. First, the principles of “through” or “insertion loss” measurements will be discussed and demonstrated. Second, the principles of return loss measurements will be discussed and demonstrated. A variety of common EMC test/debug laboratory RF devices such as RF series adapters, attenuators, probes, and antennas will characterized with one or both of the two measurements. The main emphasis of the presentation will be a 50 ohm return loss measurement setup with a best case dynamic range of 40 dB. Gregor Dzialas is Lead Auditor, Medical Division, at TUV Rheinland of North America in Boxborough MA. Gregor is currently the FDA AP Program Manager at TUV Rheinland and has been Regulatory Affairs Manager involved with the FDA Third Party Inspection Program. He has implemented and managed the NRTL program for the MHS department at TUV America, including support of OSHA accreditation application, internal audits, and marketing efforts, establishing of the pricing structure and defining the internal processes. He is authorized as Technical Certifier and Lead Assessor for various active and non-active medical product types and conducts conformity assessment to the MDD, AIMD, CMDR, and NRTL rules for type examination, lot inspection and quality system audits. Gregor’s presentation will provide an overview of the FDA’s AP Program and the manufacturer’s benefits and eligibility requirements. His presentation will cover the following areas: • Overview and history of the program • Benefits for Manufacturers • Manufacturer Eligibility • The process of AP Inspections • Current and future challenges of the program • Conclusion and Discussion Further information on our speakers and their presentations will soon be available on the NPSS web site at http://www.nepss.org. Anyone interested in setting up or attending NPSS meetings at remote locations should email the NPSS secretary with their comments. General open access for individual remote connections is presently beyond the scope of NPSS plans but satellite meeting locations where many people could participate is an option if there is sufficient demand. The intent is to provide for a few remote attendance locations where distance prohibits individual attendance at the NPSS meetings in Hopkinton. If you or anyone you know would like to give a product safety technical presentation, please contact Paul Smith, our meeting scheduler, by email at pauljsmi...@cs.com. A technical presentation should be 45 to 60 minutes in duration and be related to product safety. Although the presentation may reference your company and it’s

RE: Protectors vs breakers in the NEC
Good morning, Jim. The Code reference you cite is it, as far as interrupting capacity goes. The NFPA isn't going to stick it's neck out any further and the shouldn't. The rationale is that each application could be different, some having 10 kA, some having or 100 kA or greater fault current capacity. The engineering of any facility has to understand the utility's capacity at the service entrance and also be able to calculate fault capacities downstream. I know you mentioned NFPA 70:2005, but the latest I have in 2002. I don't know that there's a significant difference between the two versions on the references I give below. I think what you're really looking for is a combination of both Article 100 (definitions of 'identified' and 'listed'), 110.3(b) and (especially) 240.10. (Other locations discuss special characteristics for feeders, service entrances, special uses, large electrical load equipment etc.) The test programs are vastly different, with testing of branch circuit protection breakers being significantly more rigorous than for supplementary protectors, in anticipation of a much more severe electrical environment. Also, look at 240.83(c). My recollection from working with circuit breakers is that 5 kA is a gimme, provided the basic construction requirements for branch circuit protection breakers are met. Anything higher requires testing. Regards, Peter L. Tarver, PE ptar...@ieee.org From: Jim Eichner Sent: Monday, September 19, 2005 5:07 PM I'm sure it's in there...somewhere. I'm looking for where the NEC (2005 please) says that the overcurrent protection provided for branch circuits has to be a circuit breaker with an interrupt rating of at least X (I believe it's 5000A), as opposed to a supplemental protector. The closest thing I can find is... 110.9 Interrupting Rating. Equipment intended to interrupt current at fault levels shall have an interrupting rating sufficient for the nominal circuit voltage and the current that is available at the line terminals of the equipment. This doesn't really say it. It suggests that if I could go buy a supplemental protector rated for say 500A interrupt and if I could convince the electrical inspector that at the location where it will be installed (say in a sub-panel at the end of a long run of No. 14AWG wire) that's all the fault current available, then that would be ok?! I thought they had to be real circuit breakers AND they had to have appropriate interrupt ratings. Yes? No? Thanks, Jim Eichner, P.Eng.

RE: When is a cable shield not a cable shield?
I've seen quite a few good replies to this thread with some fun EM analysis. I'd like to offer a practical viewpoint (I know, I'm usually the one that's throwing Math around...so I'll take the other viewpoint this time) I have my suspicions that some items are sold as shielded just so that the manufacturer can say so. The problem is, they didn't really know shielding theory; so they didn't know enough to terminate the shield. Over the years, I have seen quite a few shielded items that aren't very well terminated or very well shielded. I'm not sure what the case is with this particular cable. Maybe it's the result of a cable manufacturing that doesn't understand shielding theory; or maybe it's meant for a special purpose other than shielding. The braid will offer some shielding even if it isn't terminated...much of this depends on the length/width ratio of the cable, the frequencies of interest and the type of signals on the cable (common mode, differential mode, balanced, unbalanced...) From a practical standpoint, I would take a hard look at this cable. If you don't have an EMI problem with the cable; then I would try an unshielded version in order to save cost. If you do have an EMI problem with the cable; than I would either try to add filtering to the signals on the cable (and then see if you can remove the shielding)...or I would look into getting a cable with a shield that has proper termination.

Re: When is a cable shield not a cable shield?
If we grant that an image plane can reduce radiated emissions when placed adjacent to PCB, it seems it would also follow that an image plane next to a ribbon cable could perform likewise. However, if that were the intent, it would seem cheaper and more effective to include the image plane as a foil layer built into the ribbon cable assembly. If a manufacturer has gone to the trouble and expense of weaving a braided shield around the ribbon cable, then the only way to get the maximum achievable performance from that shield is to peripherally terminate it at both ends.

I'm a first time poster. An interesting discussion! I remember doing some research 10 years ago in a previous employment looking at the radiated emissions from pre-fabricated Printed Circuit Boards with and without (floating) groundplanes. Dimensions of the board were around 15cm by 10cm with simple trace configurations (go and return) to a battery. The (common mode CM) radiated emissions between 30MHz and 1GHz were greatly reduced with the floating groundplane in place. This is due to the image of the CM current in antiphase causing the far field cancellation. I assume a similar principle would apply to ribbon cable with a floating shield assuming good coverage?

RE: When is a cable shield not a cable shield?
Dear Group, Further to my earlier email, I did a web search and found that 'groundplane' ribbon cable does exist (was vaguely aware of it from memory) and that it is claimed to have better transmission properties. Improved signal integrity usually means lower emissions. The cable comes with or without drainwire for the groundplane. Not sure how this cable would compare with a fully enclosed shielded ribbon with the shield floating.

Hi Group. I'm a first time poster. An interesting discussion! I remember doing some research 10 years ago in a previous employment looking at the radiated emissions from pre-fabricated Printed Circuit Boards with and without (floating) groundplanes. Dimensions of the board were around 15cm by 10cm with simple trace configurations (go and return) to a battery. The (common mode CM) radiated emissions between 30MHz and 1GHz were greatly reduced with the floating groundplane in place. This is due to the image of the CM current in antiphase causing the far field cancellation. I assume a similar principle would apply to ribbon cable with a floating shield assuming good coverage?

Re: When is a cable shield not a cable shield?
The definition or range of the term low frequency was bounded by saying the cable was electrically short. And the point is not to stop eddy currents from flowing, but to maximize and control where they flow. Both of these functions are achieved by using a high conductivity shield with low impedance shield terminations. Mr. Tang is correct that once the shield becomes electrically long the magnitude of a localized shield current is less dependent on the shield termination impedance. But that is the case that was covered at the beginning of this thread, before magnetic fields were specified as the culprit to be controlled. The reason for terminating the shield at both ends at high frequencies (cable electrically long) is to contain the eddy currents on the interior of the equipment enclosure, of which the shield is an extension, just as a tunnel or skyway between two buildings becomes an extension of the buildings it connects.

Low frequencies is really a relative term these days. Depending on the dimension of the shield, a 1GHz eddy current can drive the shield into a monopole (if one end grounded, the other end floating) or dipole (both ends floating). Eddy currents still flow, and opening one or both ends of the shield does not stop the eddy currents. This is why fields and waves are so interesting.

Mr. Woodgate is correct in the general sense of shielding against all forms of radiation at all frequencies, but in the specific case of magnetic radiation (which to me at least implies low frequency, an electrically short cable) the magnetic field circulates around the cable. That means that eddy currents will flow in a loop which is penetrated by that vector. That means that the shield has to form a loop end-to-end to allow eddy currents to flow and oppose the field which caused it.

RE: looking for a UL Listed Power Supply 24vAC out @ 5amps
Hi, Camille. From: Camille Good Sent: Wednesday, September 14, 2005 1:07 PM Actually, I think you are outside of Class 2 limits with 24 Vac 5 A, as the limits of Class 2 are maximum 30 Vac / 42.4 Vdc Although you are correct about Reginald's needs exceeding Class 2 limits for wet locations (his original post indicates as much), I would like to point out that Class 2 limits are not quite as described. For wet environments, the voltage limits are 21.2 Vpk and 30 Vdc. Reginald - While your assessment is generally correct, you're likely to have a *very* difficult time finding a Class 3 supply or transformer with the ratings you mention, since Class 3 current limits are at 150/Voc, and assuming a near 30 Voc from a 24 Vac transformer/supply, the maximum output current is required to be 5 A or less. That's a tough nut to crack. Please pardon my relating a memory: I have met one character, who in about 1987 worked for Honeywell (and I at UL, testing, among other things, Class 2 transformers), that designed a transformer beautifully at the hairy edge of Class 2 (dry location) limits, using a core size more closely matched to 1 kVA and wire sizes typically used for much larger current output transformers. I told him it couldn't possibly pass muster, but in the end had to eat crow. All this by manipulating a core air gap; the large core and wire sizes had the thing barely over ambient under short-circuit conditions for eight hours (part of my customers design intent). Impressive bit of trickery ... er ... I mean engineering. Wish I could remember his name. Regards, Peter L.

RE: FCC Part 15 unique identifier
For certified equipment the FCC identifier is a unique number established by the FCC to identify the product and the manufacturer providing the FCC with traceability of the equipment in case of a complaint in the field. Prior to the DoC process all (?) class B equipment would be tested and the report sent to the FCC for review. Upon successful review of the report the FCC would issue a unique - unique first to the manufacturer (I believe it was the first three alphanumeric characters) followed by a unique - to the product itself - set of alphanumeric characters. Put together the manufacturer and the specific product was identified. With the inception of the FCC's Declaration of Conformity program (as opposed to the EU DOC) the need for a unique identify was eliminated for this class of equipment. I believe it could still be used if there is some underlying reason for the manufacture - for example making the equipment for someone else.

FCC Part 15 unique identifier
For a switch-mode power conversion product that is physically quite small, we are eyeing the following Part 15B easement regarding markings: (5) When the device is so small or for such use that it is not practicable to place the statement specified under paragraph (a) of this section on it, the information required by this paragraph shall be placed in a prominent location in the instruction manual or pamphlet supplied to the user or, alternatively, shall be placed on the container in which the device is marketed. However, the FCC identifier or the unique identifier, as appropriate, must be displayed on the device. So far so good, but what is the unique identifier? I find no other reference to it anywhere, including in the Definitions. The FCC identifier is not an option for us as we are under the verification process where we have no FCC identifier.

Re: NRTL Factory Inspection Question ...
I think that there is a good definition on the OSHA site concerning what a factory is. I believe it indicates that the factory is not just where the label gets put on (an old time classic consideration) but where assembly does take place. Not just putting modules in and shipping out. Scott - Please not Mr. Barrows :). - Original Message - From: McInturff Gary mailto:gmcintu...@spraycool.com To: peter.tar...@sanmina-sci.com ; emc-p...@ieee.org Sent: Tuesday, September 06, 2005 12:37 PM Subject: RE: NRTL Factory Inspection Question ... You may find that many of the different factories are under some NRTL contract already. If so you won't need a new specific contract with them. Following up with Peter's comments about wire harnesses, if you choose a factory that is already approved to build UL (for example) recognized wire harnesses they have already signed the appropriate UL documents. These documents are general in nature and not tied to specific cable assemblies or companies for which they can manufacture harnesses. They don't require amendments when a new customer comes into the cable harness manufactures list of clients. When outsourcing system components I look for companies that already build NRTL approved items. Another example is recognized or certified plastic components. In both of the these cases the actual part manufacturer has already signed agreements to allow the NRTL's inspection authorization, and they are already aware of the items they must control and track for the audits. This doesn't directly address traceability but it does give you a leg up on obtaining traceability. These manufactures are pretty aware of what you will be needing to prove the traceability so you don't have to set up whole new processes with them etc. From: emc-p...@ieee.org [mailto:emc-p...@ieee.org] On Behalf Of Peter L. Tarver Sent: Tuesday, September 06, 2005 8:04 AM To: emc-p...@ieee.org Subject: RE: NRTL Factory Inspection Question ... Doug - In addition to the other responses, here's more food for thought. Theoretically, there's nothing to prevent you from labeling and performing all normal 100% of production testing on the product at your facility, rather than the factory. However, the practicalities of traceability of some parts and components can be extraordinarily onerous, especially for molded or processed polymeric parts, wire harnesses, wire and connectors (all types). For wire, in particular, the labeling on the spool is what is relied upon by auditors for suitability, since no NRTL (that I'm aware of) has certification marks for wire off the spool and surface markings are normally not relied upon for proof of certification. You may be able to work out a paper trail with the NRTL for some parts, with the factory forwarding a sheaf of paper with each lot, but this won't work for everything. In addition, managing noncompliant products could be an enormous headache. Who'd do the rework? What if the rework is extensive? What if the one lot the factory neglects to attach the sheaf of papers is the one the auditor happens to see in you facility? In my view, it's worth the money to put all of this off on the factory(ies). In your hypothetical case, with ten potential factories, it would likely be best to limit the number of factories to a few at any given time and get them under a contract with the NRTL. Even if all of the factories must be included, for whatever reasons, it's probably for the better to get them all under contract, because each factory will have a learning curve to build a product and you can't be certain what you'll receive during regular production will compare in all respects to a first article, where it should expected that more care will be applied than for regular production. Regards, Peter L. Tarver, PE ptar...@ieee.org From: Doug McKean Sent: Sunday, September 04, 2005 7:39 PM To: emc-p...@ieee.org Recently, I had a discussion with an NTRL regarding product factory inspections. I was under the impression that where the label was applied, that was where the factory inspection would occur. And, if the contract noted a different company where the manfacturing was done and being that was typically (not always) where the lable was applied, that was inspections would happen. Not so, according to these people. This was in response to a hypothetical situation I gave them to consider. For instance, say your company has sells a product in your companys name. But, you have assembly done at any number of contractors. And the NRTL label is applied at your company. Even if the contractors aren't on the contract with the NRTL for whatever reason, the factory inspector will inspect as much as possible the product at your site, then inspect the contractor site even though it is not on the contract. Basically at their discretion. The result of this is ... if say your company has ten contractors on a list of approved

Should have put this URL in my original msg: http://www.osha-slc.gov/dts/otpca/nrtl/nrtlregs.html which is only says that adequate controls for conducting follow-up inspections of the actual production of items to evaluate conformance with test standards and conducting field inspections to assure proper use of its marks or labels But this provides more detail on when an NRTL may accept 3d party test data (which is what they are doing when they accept your test data on the out-sourced component): http://www.osha-slc.gov/pls/oshaweb/owa isp.show_document?p_table=FEDERAL_REGISTERp_id=13454 But, it does NOT say that the NRTL shall accept any 3d party test data; so the agency can require any out-sourced mfr to comply with the same FUS audits performed at the end-use mfr. luck, Brian From: Scott Barrows [mailto:sbarr...@curtis-straus.com] Sent: Tuesday, September 06, 2005 7:00 AM To: Brian O'Connell; Jon Griver; emc-p...@ieee.org Subject: Re: NRTL Factory Inspection Question ... Hi All, For a clarification of the NRTL requirements for Factory inspections. Go to the OSHA website and look it up. It is a interesting place and defines the guidelines that all of the NRTL's must follow. Subject to interpretation of course, but if you want to argue a point that may save you money or aggravation, give it a shot - it is the law, I believe.

CENELEC requirements do not necessarily pertain to NRTL requirements; which are driven by United States OSHA requirements... When acting as an NRTL, I've yet to see any two agencies perform a FUS audit using the same procedure, having the same requirements. If a safety-critical component does not bear a mark that would indicate that it is an NRTL recognized component, then most NRTLs will require that the mfr be audited. If your company has an approved quality-control process, and can demonstrate that your receiving performs 100% test IAW the scoped standard, then they would probably accept the component if the report specifies the mfr and test requirements in the construction details. luck, Brian -Original Message- From: emc-p...@ieee.org [mailto:emc-p...@ieee.org]On Behalf Of Jon Griver Sent: Sunday, September 04, 2005 10:32 PM To: emc-p...@ieee.org Subject: Fw: NRTL Factory Inspection Question ... Doug, CENELEC has a document, CCA-201, Factory Inspection Procedures, CCA Harmonized Requirements, which defines the manufacturer's premises/factory location as the location where the final assembly and/or testing of certified products normally takes place and the Certification Mark is applied. The document also defines sub-contractors and out-workers, but states that inspecting them is the manufacturer's responsibility. In my experience the European Test Houses use this document as guidelines for their own procedures. I don't know if the document is used by NRTL's. but at least the NRTL's with European main offices should know of the document. In my experience, labelling the certified product is literally a symbolic act. The substantive act is final assembly and testing, particularly safety testing (hipot, etc.) if this is necessary for the product, and this defines where inspection should take place. Regards, Jon Griver http://www.601help.com The Medical Device Designer's Guide to IEC 60601-1 Recently, I had a discussion with an NTRL regarding product factory inspections. I was under the impression that where the label was applied, that was where the factory inspection would occur. And, if the contract noted a different company where the manfacturing was done and being that was typically (not always) where the lable was applied, that was inspections would happen. Not so, according to these people. This was in response to a hypothetical situation I gave them to consider. For instance, say your company has sells a product in your companys name. But, you have assembly done at any number of contractors. And the NRTL label is applied at your company. Even if the contractors aren't on the contract with the NRTL for whatever reason, the factory inspector will inspect as much as possible the product at your site, then inspect the contractor site even though it is not on the contract. Basically at their discretion. The result of this is ... if say your company has ten contractors on a list of approved vendors with which do business (just as an example for the sake of argument) for possible assembly contracts and at any time you do business with just

Re: WEEE Process for US Mfr's
Chris, I was never in any meetings involving the Commission when the WEEE Directive was being drawn up, so I cannot comment on the accuracy of you assertion below. It seems more likely to me that - if the Commission even considered distance selling at all - they took the view that at the present time the vast majority of electrical products were not sold over the net. Hence, the priority could have been to tackle the biggest chunk of WEEE first and leave distance selling to the inevitable next tranche of legislation. What do you mean by to clean up on all the internal white and household goods? We may have an issue here on American vs. British English, but I'd like to be sure.
