RE: Receiver Requirements in ETSI 300 220
EN 300220-1 contains the test requirements, but its reference is not published in the OJ. EN 300220-3 is published in the OJ and lists the sections of EN300220-1 that apply in order to comply with the essential requirements concerning article 3.2 of the RTTE Directive. As you noted, it lists requirements for the receiver as well as the transmitter. If you declare compliance using the standard, you will have to comply with all requirements of EN 300220-3. I once used the TCF route and the Notified Body told me that the blocking requirement was not an essential requirement. Go figure. Oh, and, of course you also have to comply with EN 300 683 or its replacement, EN 301489-1 and EN 301489-3.

Conducted Emissions Testing of Intentional Radiators
When are testing a FCC Part 15 intentional radiator operating below 30 MHz, and have encountered the situation where the emissions from the antenna is being received by the power cord and causing the system to fail conducted limits. The transmitter complies with the conducted limits with a dummy antenna load. The transmitter has a detachable antenna and a 12 ft antenna cable. Is it permissible to demonstrate compliance with the conducted limits by 1) using a dummy antenna load, or 2) placing the antenna outside the chamber, or 3) some other way? Obviously, whatever method we use must be acceptable to the FCC.

RE: Vehicle Mounted PCB's
David, my suggestion is to determine which is the worst case EMC environment - the applicable standards or the actual environment - and design for that. We had a similar problem with a particular CCTV installation. The CCTV rf immunity standard specifies 10 V/m; however, the guard watching the CCTV monitor was using a hand held radio that produced a field much higher and the interference was unacceptable to the customer. We had to add fixes to increase the immunity level far beyond what the standard required. You may have a similar problem. Good luck.

RE: Shield Room Lighting
We have the same frequent burn out problem and we also have attributed it to the filters. We just keep replacing them. Has anyone tried the rugged bulbs marketed for use with garage door openers or ceiling fans or have tried the extended life bulbs? Do they last longer in chamber use to justify the cost? Richard Woods Sensormatic Electronics Tyco International -Original Message- From: POWELL, DOUG [mailto:doug.pow...@aei.com] Sent: Thursday, October 31, 2002 12:49 PM To: EMC-PSTC (E-mail) Subject: Shield Room Lighting Greetings all, I wanted to share an experience and I hope benefits someone else. My past experience with shield room lighting is that incandescent bulbs frequently burn out, about once every 2-3 months. I tried ruggedized lamps of various sorts, still with the same results. Obviously, I wanted to avoid florescent lighting because of the huge fields they radiate. After some investigation and discussions with co-workers, it became apparent that the problem is the line filter for service power in the room and the tungsten filament in the bulb. These line filters are typically have a really large line to neutral capacitance which significantly lowers the source impedance of the line. Coupled with this, tungsten experiences a fairly high in-rush current owing to it's very dynamic negative temperature coefficient. I toyed with idea of using inrush limiters but I thought there had to be a reliable low-tech solution. And at all costs, whatever solution I used, I wanted to avoid injecting unwanted RF noise into the room. I discovered traffic light signal bulbs. Available from a few sources, these bulbs have at least 5 filament supports, heat dissipaters and reflectors and are designed for continuous on/off operation in all sorts of weather conditions. They even keep working when the hanging fixtures bang into each other in wind storms. I also learned that these bulbs have about a 1 to 2 year life expectancy in these conditions, so I tried it out in my room. So far, I've logged a full year of use on 4 x 150W bulbs with no burn out. And no, I don't just leave them turned on. If you want to try this, do it soon because it appears that these bulbs may become a thing of the past and prices may be driven up. Over the last few years, many cities and counties are replacing their incandescent bulbs with the new LED bulbs and with great success. As soon as a white LED light becomes available I may try it out, although I guess I could use red LED lamps since I used to be in the navy. Best regards, -doug Douglas E.

Scott, you do not have to test for power line harmonics or flicker if 1) your product is not mains powered, and 2) you have no intention of selling it along with a particular power source, and 3) you do not specify that it be used with a particular power source.

Fellow Listees: There were some recent threads regarding what testing is required for a product that obtains power from a supply external to the product and maybe not supplied by the manufacturer. I think the questions were related to EFT or surge. I have a similar situation. Our products are network powered; that is, there is a ferroresonant power supply connected to the network and we just tap into that available power. This is CATV land and not Telco. We do not make the supply nor do we sell them. Our products have switching supplies which run on the quasi-square wave provided by the ferroresonant supply. Voltage of the supply is in the 60-90 VAC range. Question is: EN 50083-2 : 2001 (4.1.2 Disturbance Voltages From Equipment...) says that if our products fall within the input current range of EN 61000-3-2, then the tests and limits of that standard apply. Then EN 61000-3-2 : 2000 (1. Scope) says that the standard applies to products intended to be connected to public low-voltage distribution systems. One argument says that we are not connected to the public low-voltage distribution system, instead the ferroresonant supply is. Therefore, since we ARE NOT connected we do not need to do the harmonics test. The flip side argument says that we still have to test harmonics because the supply does nothing but provide power to our product and therefore we ARE connected. Understand that this system consists of power supplies and amplifiers, etc. from one or more than one supplier (read that more than one manufacturer). We cannot guarantee we are the sole provider here, in fact will most likely not be the sole provider. Especially since we do not manufacture or sell power supplies. So all powerful and wise list, what's a mother to do? Do I, or do I not, test? Am I required to test? Have I missed something? Thanks for all of the wisdom you are about to impart.

RE: Layered Reinforced Insulation
OK, I'll get more specific. I have an external interconnecting cable that contains hazardous voltages. Because of the application, in the USA I must use UL Listed CL3P cable which is rated for use in risers and air handling spaces (smoke requirements of the National Electrical Code). The insulation system of a standard CL3P cable consists of the wire insulation and external jacket, and the sum thickness is 0.4 mm. It is not clear that the insulation parts are constructed of the same material. I must determine if the cable complies with the reinforced insulation requirements of UL60950/EN60950, or if I need to have a special cable constructed. Someone mentioned that the two insulations must be the same material in order for the system to be classified as reinforced. I cannot find that requirement in the standard. Nor can I find any statement that says that a two part insulation system must consider one part to be basic insulation and the other part to be supplementary insulation. Frankly, I can find nothing in the standard that indicates why the particular construction of this cable is not allowed to be considered as reinforced insulation. The only issue at hand, it appears, is that it must be shown that the insulation is mechanically durable in the intended application. That is where I rely upon the the UL Listing - they seem to believe that it is perfectly acceptable for a 300V interconnection application - at least the kind that my equipment will employ.

Layered Reinforced Insulation
Consider the insulation construction for an external interconecting cable connected to secondary hazardous circuits of ITE (EN60950). Is it permissible for the reinforced insulation to be constructed of two layers (e.g., conductor insulation plus external jacket) if the total thickness is at least 0.4 mm? Clause 2.2.1 appears to allow it; however, clause 2.9.4.2 appears to indicate that layered insulation can only be used internally.

Performance Criteria A
Most of the CENELEC immunity standards specify performance criteria A as follows: The equipment shall continue to operate as intended without operator intervention. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer when the equipment is used as intended. The performance level may be replaced by a permissible loss of performance. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, then either of these may be derived from the product description and documents, and by what the user may reasonably expect from the equipment if used as intended. However, ETS 300 683 and ETSI EN 301489-1 and -3 (and I presume the other parts) read less clearly as Operate as intended and No loss of function. Can one presume that CENELEC's more well defined wording of Criteria A can be applied to the ETSI standards? Specifically, can the manufacturer specify a degradation of performance or loss of function as long as the degraded performance is not less than what the user may reasonably expect from the equipment if used as intended.

RE: LED's and laser safety?
Gary, I have to be concerned about LEDs also and have found that I need to consult EN 60825-1 in order to determine the design and documentation requirements for Class II LEDs. Our EU safety agency requires that we demonstrate compliance even with Class 1 devices. For the lower emission LEDs, compliance can usually be demonstrated by a review of the LED specifications and perhaps a fault test. Otherwise the emissions must be measured. The standard was an requirement for us in one situation where we used a high intensity Class 2 LED inside the product in order to obtain the necessary light outside the product. The external emission was Class 1, but labels and documentation was required for service.

Why would a mfr get a UL recognition approval for a commercial ITE style single phase 155-230vac computer style product but for that same product get the TUV GS mark? Mfr is a stateside company. Product to be used in restricted areas with trained personnel only. But, one that essentially anyone could buy. What's the advantage of getting such a mixed set of approvals? It's not really a mixed set of approvals. UL must have considered the device to be incomplete in some way (does it have an enclosure?), therefore they Recognized it as a component as opposed to Listing it as a finished product. The GS Mark has no mechanism for delineating between components and finished products - both can receive GS approval. Hence the TUV GS mark.

RE: Electrical safety in Canada
Be careful. First a safety agency has be accredited by the Standards Council of Canada (I think that's the name). However, their accreditation must now be accepted by each of the provinces who actually have legal jurisdiction over electrical installations. When UL first claimed accreditation, they found out the hard way that they needed to take the next step and gain provincial accreditations. So, be sure that the safety agency has been accredited by the provinces. CSA obviously does, and I received assurances from UL, MET and TUV Rheinland, but I cannot speak for other USA based agencies.

On Low Frequency Measurements Issues, Conformity, pp. 22-28, August 2002. After reading your posts (especially the one from Michael Peters on 6 Sep 2002) and more studying of FCC Part 15, I believe the best procedure for FCC testing of intentional radiators is: 1. Measure radiated and conducted emissions just as we would do for any unintentional radiator. 2. Measure radiated and conducted emissions from the lowest radio frequency generated in the device on up to the specified highest frequency, to meet clause 15.33(a). I had followed this procedure to FCC test two 418MHz telemetry transmitters for a client. In this particular case I was comfortable, because Don Bush had tested previous products for this client this way, and they had all been licensed by the FCC without any problems. But I wanted more justification for not testing intentional radiations to FCC Part 15 clause 15.209(a) below the fundamental frequency, than just because we've always done it that way. Thanks all!

FCC Testing 2.45 GHz Transmitter
Consider a 1W frequency hopping, spread spectrum transmitter operating at 2.45 GHz. The FCC released a Public Notice on acceptable test methods (Filing and Measurement Guidelines for Frequency Hopping Spread Spectrum Systems) where they recommend that the spurious radiated emissions in the restricted bands are to be measured with a high pass filter. There is a restricted band at 2483.5-2500 MHz. Given a 1W transmitter and a spurious limit of 500 uV/m at 3 m, it would seem that I need a very sharp high pass filter or a very good notch filter to measure in that band. Is this feasible? It would also seem that a notch filter or low pass filter is required for measuring spurious emissions in the restricted bands below 2.45 GHz. There is a restricted band at 2310-2390 MHz. Again, is a filter feasible? I am aware of semi-custom filter suppliers, but are there any off-the-shelf filters available?

RE: Telephone headsets
Chris, the CE marking indicates that the product complies with all applicable directives. The only two directives that might apply is the LV and EMC directives. However, the LVD does not apply since the working voltages are low. The EMC directive would apply if your equipment is likely to cause interference or likely to be susceptable to interference. I tend to believe that your equipment is not likely to cause interference, but it might be susceptable to magnetic fields. So some immunity requirements may apply. If so, your Declaration of Conformity would only claim compliance with the EMC Directive. If the EMC Directive does not apply, then no Declaration or CE marking is required.

The headsets will connect to an OEM audio amplifier that has been evaluated to the LVD, and seems to contain all the necessary isolation (we are not even selling the amplifier).

On the whole, of course safety is involved; but that is not the question at hand. What I am trying to get at is that a particular requirement/test may not be safety related in a particular application. That occurs from time to time in ITE testing, so is there any reason why the same investigative rationale cannot be applied to the components used in ITE, such as lasers/LEDs, where the standards for those components have a normative reference in the ITE standard?

Therefore if a product is still being manufactured for sale after the DoW of standard A, then the product must be re-evaluated according to the new standard B. (An exemption being those items returned for repair and not modified/updated/upgraded). If the product was no longer produced and placed on the market after the DoW then there is no issue. My acquaintance notes that if the product was tested to standard A, as long as it has not been 'updated, modified, or changed in anyway' since the initial compliance test, it can still be manufactured and placed on the market after the DoW without re-test.

I assume it is 24 Vac, because that is a common household control voltage, and because the only difference in each model is the transformer. I'm not up on the legalities, but I would say that your differential mode emissions will be maximized using the low voltage model, since the current draw will be greatest. Common mode emissions will be greatest with the 230 Vac model, because the potential applied to stray capacities is the greatest. The 120 Volt model is intermediate for both kinds of conducted emissions.

Laser Emissions Measurement
Consider a Class 1 Laser Product. Once the protective cover is removed for service, it is physically possible for the 12 mm probe to be inserted into the beam where Class 2 levels are present; therefore, human exposure of a finger is possible. However, it is not physically possible to directly view the beam nor is it possible to place the measurement instrument into the beam at the specified measurement distance of 100 mm. What are the measurement requirements in this case? Must I take the system apart such that the beam can be measured? If not and since Class 2 limits are based upon viewing considerations and not finger exposure, do I get off the hook for needing the Class 2 warning label on the protective cover?

Fiber Optic Systems
We plan to purchase for resale an LED fiber optic transmitter, receiver and cable that will provide a communications link to our products. While we will resell these devices as optional accesssories for our products, the accessories will retain the original manufacturer's brandname. We will obtain the products from EU based sources, so we will not be involved in inportation. The transmitter is a stand alone product with its own power source. The receiver, on the other hand, is a module that attaches inside our equipment enclosure and receives its power from our equipment; therefore, the fiber optic cable must enter our equipment enclosure. I need to determine: 1) if and how EN60825-2 will apply to any of these accessories - i.e must it appear on any Declaration of Conformity? 2) if my company must issue any Declaration of Conformity that lists EN60825-2.

This is evidenced by the statement from CENELEC's web site relating to EN60950-1, which is Supersedes EN 60950:2000. The IEC's website provides this statement This first edition of IEC 60950-1 cancels and replaces the third edition of IEC 60950, issued in 1999, and constitutes a technical revision. For specific requirements for particular product variants, other sub-parts (EN60950-xx) would be necessary. BTW, EN60950-21 (remote power feeding) is the only sub-part on record with CENELEC according to their website. In addition to Part 21, the IEC's website also describes Part 22: Equipment installed outdoors and Part 23: Large IT equipment with integral robotics. So, I believe that if products do not apply to any sub-part, then I would presume that sub-part 1 would be the only sub-part that would apply. Comments?

RE: Measurement Consistency of OATS
We have noticed a change in our OATS characteristics depending upon the dampness of the area. It is especially noticeable this time of year when we get a lot of rain in Florida. Does anyone else experience this phenomena? More to your question Mat, the major contributors to the measurement uncertainty would be the repeatability of the setup of the EUT and test equipment (e.g., distance from EUT to antenna) and the stability/drift of the EUT and test equipment. Half of these parameters are human based (setup) and should vary less if the same person performs all of the tests. I have not seen a paper on this subject. Unually these variations are lighly covered in texts on measurement uncertainty.

Home Network
I want to upgrade my 1MB/sec home network that uses my phone line. I have several choices, but would like to hear from others before I make the leap. 1) I understand that 10MB/sec Ethernet will operate on Cat 3 twisted pair and that normal phone wiring is Cat 3. If use my existing phone wiring (multiple pairs running all over the house) what are the chances that I will have interference coupled to my telephone or vice versa? 2) If I use a 10/100 MB network interface card, are there options to force the network to operate at 10MB? 3) My other option is go wireless, but there are two competing standards RF and 801.11b. Some reviews indicate that the latter may soon be replaced by another 801 standard. Also, some reviews indicate that 801 is not as good a product as one would be lead to believe.Is wireless networking in the home effective and if so, which standard should I use.

Mexico Mains Voltage
I understand that Mexico uses a 220V Wye distribution system such that the single phase voltage is 127V. What low line and high line voltages should one consider as being normal where equipment should continue to operate as intended? I ask this because I doubt that 127V is really the nominal voltage with an expected variation of +6% and -10% as found in IEC60950.

RE: Network Camera and EMC?
John, the ENs that you will use will depend upon the intended application. For emissions, EN 55022 applies for ITE applications, EN55103-1 for professional use and there may be other standards for other applications such as instrumentation and process control. There are at least two immunity standards: EN50130-4 for surveliance/alarm system applications and EN 55103-2 for professional use.

RE: An ESD question
Humidity is not the only variable, and may not be your major variable. Repeatability of ESD results is a statistical problem. Consider the variables: -humidity -approach speed (for non-contact discharge) -angle of the probe (for non-contact discharge) -synchronization of the ESD application with the various logic states of the EUT -rise time and peak di/dt variance as applied ESD voltage is changed -variance between ESD guns And I am sure there are more variables. The only way one can really determine a product's real ESD immunity is to apply thousands of hits at different voltage levels and apply a statistical evaluation. In the end, one can only say that the equipment is immune to X volts with Y confidence.

We have an ESD field failure which is occurring in dry hot countries ( no surprise )which can be recreated with an ESD of -800V. In an attempt to get a high incidence of discharges we used a dehumidifier to create a dry environment. The result was a reduction in discharges. Thinking the problem through -now- as a dry atmosphere will encourage the production of high level ESD and a humid environment inhibits the charge to a lesser level, presumably because it 'leaks' away. Then is it wrong for us to attempt to 'dry' the local atmosphere in the hope of gaining consistent ESD from an ESD gun, that is to say the more humid the environment the more efficiently the discharge will transfer to the victim? Incidentally, to add to the thread regarding intermediate level testing for ESD and EFT. This exercise has revealed different failure mechanisms at different ESD levels.

RE: Coaxial Switches - use with spectrum analyzer and gear?
Here is what I have learned about switches this week. There are very low power rated switches for usual ATE applications, power switches (circa 200W) and high power switches. For power switches, the insertion loss is in the order of 0.2 db over a very wide frequency range (DC to many GHz). The power rating is based upon the power than can be conducted through the switch - not switched. The power must be turned off before switching or be about 1-10% of the rating while switched to prevent premature failure of the contacts. A minimum power of about -20dbm must be used to overcome the losses in the switch. Options include type of connector (e.g., SMA, N, indicator contacts, latching type, and others. GPIB controllers are available for controlling switches. My particular application is to add to our radiated immunity setup. We are adding a 1-2GHz amp and directional coupler. I have to switch the signal generator between two amps, switch the antenna to the directional couplers and switch the power meter to the couplers - 3 relays. I plan to use a simple, manual two position switch to control the three relays and think about automation later. You can find a wealth of information at www.dowkey.com.

In our pre-compliance lab, we've got a pair of LISN's, a LISN-mate type thing that I'll call a DMRN (DM rejection network), a transient limiter, some clamp-on RF current probes, an amplifier, the front end of the analyzer, and a 50 ohm terminator. All this gear is connected and unconnected a hundred times a day when we're deep into trouble-shooting, and I'm sick of doing up and undoing coax connectors. I don't trust push-on coax connectors. What I envision is a system with a few of these coax switches in it. The analyzer input would go to a switch that selected either the amp (used only with the clamp-on probes) or the transient limiter (used with the LISN's). The limiter input would go to a switch that selected between the output of the DMRN or the Line LISN or the Neutral LISN. Etc. You get the idea. Is there anything to stop me from using coax switches with suitable CW power, insertion loss, and frequency spec's? Am I headed for trouble if I have 2 or 3 of these switches in the signal path, due to cumulative insertion loss? Thanks for your feedback, Regards, Jim Eichner, P.Eng.

Class 2 LED in ITE
We are developing an ITE product for the EU market that includes a Class 2 LED that produces Class 1 emissions outside the product. After review of EN60950 and EN60825-1, I believe that the following requirements apply. The clause references are in parentheses. When assembled for normal operation 1. No part of the human body may be exposed to Class 2 emissions (3.16) 2. An inserted 12 mm diameter probe up to 80 mm long cannot intercept Class 2 emissions (3.3.2) 3. No part of the human body may be exposed to reflections of Class 2 emissions from a flat surface introduced through any opening in the protective housing (3.32) 4. Class 1 Laser Product label required on product or in information for the user (5.2) When being serviced 1. A tool shall be required to gain human access to Class 2 emissions (4.2.2) 2. Caution - Laser Radiation (or laser light) When Open, Do Not Stare Into Beam label on cover. Light may be substituted for Radiation and LED for Laser (5.11 and 5.12). TUV GS marking requires the warning to be in German (EN60950, Annex ZC, 1.7.14). User Information The following information is to be supplied in user information, if any (6.1). The information must be in one of the accepted languages of the country (EN60950, 1.7.14). 1. Instructions for proper assembly, maintenance, and safe use including clear warnings concerning precautions to avoid possible exposure to Class 2 emissions. 2. A description of the Class 2 emissions (e.g., wavelength) 3. Reproductions of all required labels and hazard warnings with the location on the product noted. Purchasing and Servicing Information 1. In all catalogs, specification sheets and descriptive brochures, the safety classification (Class 1) shall be stated (6.2a) 2. Adequate instructions for service procedures including warnings shall be provided to servicing dealers, distributors and to others upon request (6.2b). 3. Service instructions intended only for service personnel may be in English (EN60950 1.7.14), except that TUV GS marking requires the instructions to be in German (EN60950, Annex ZC, 1.7.14). Did I get anything wrong or is there anything missing?

RE: General Product Safety Directive
Well, this series sure took a left turn and accelerated hurriedly out of site of the original intent which was to determine what the term consumer means as used in the GPSD. The imaginary product example I put forth was intended solely to support the question, and I in no way advocated that such a product be placed upon the market without the proper safety analysis. Now, back to the original question. I found the following definition of professional apparatus in EN 55103-2 (immunity for professional A/V equipment): Apparatus intended for use in trades, professions or industries and which is not intended for sale to the general public. The scope of the standard says that the standard does not apply to consumer apparatus. So, it seems that the CENELEC authors of this standard are of the opinion that there is a difference between professional and consumer apparatus. If the authors are correct, the professional equipment I described is not included within the scope of the GPSD. If that is true, what safety related Directive, if any, applies? The only one I could find is the Liability Directive, 85/374/EEC. The closest that document comes to having an essential requirement is that Lack of safety which the general public is entitled to expect determines the defectiveness of a product. Could it be that the regulation of safety of these types of products are the responsibility of the member states and governed by national worker safety regulations? Seems weird that there is a gap in the harmonization process for these types of products.

RE: CE MARKING A SYSTEM
Gordon, cosider constructing a Technical Construction File (TCF) and submitting it to a Competent Body. Your product may comply with the essential requirements when operating in its intended environment without the need to apply the full industrial strength tests. At least, you could make that argument to the CB. Richard Woods Sensormatic Electronics Tyco International -Original Message- From: Gordon,Ian [mailto:ian.gor...@edwards.boc.com] Sent: Tuesday, April 30, 2002 4:57 AM To: 'IEEE EMC SAFETY PSTC' Subject: CE MARKING A SYSTEM Can anyone advise the course of action in applying a CE mark as regards EMC to a system some of whose component parts are not built by us and whose D of C's claim light industrial immunity. However, the system has been running in very harsh environments e.g. plasma etch applications at customer sites and we wish to claim industrial level immunity for the system. The system is obviously fit for purpose in the intended environment. We have performed radiated testing to this level on the whole system. Unfortunately if we surge test these light industrial components which form part of the system we are certain they will fail at the appropriate levels. One component is an industrial PC. Does anybody have any suggestions as to what action to take to allow us to apply the CE mark and claim industrial immunity?

ISN for EN55022 Network Testing
I would like to know what members of the group are using for an ISN for network emissions testing per alternative 1 of EN55022:1998 (clause 9.5.1.1). Can a CDN-T2 per EN61000-4-6 be used? Can the EM clamp per EN61000-4-6 be used as the ferrites for testing with shielded cables per C.1.2?
