RE: Blocked ventillation testing
Bob, UL 60950 1.4.14 states that faults shall be applied in turn, and one at a time. On the other hand I take a look at the practical operation of the unit being tested. For example one of our units is a floor standing unit that sits off the ground by about 2 inches. Since there will always be paper around my unit it would be safe to assume that some one may stick a small stack of paper under the unit (I have done it) and therefore block my intake vents. If the paper is big enough in size they could also inadvertently block the exhaust vents as well by doing the same thing. So I typically block all the vents of my printers when I do testing. This will assure that the printer will operate and fail safely in the event that the operator wants to store important documents under our printers.

My previous experience has been that one side is blocked at a time. Blocking more than one side at a time was considered multiple faults. If it passes blocking all vents at once shortens test time, but is this method necessary? What is the experience of others?

RE: RFID tags
The ones we are using have a silicon die. When the tag receives a signal it activates the die and causes a change in impedance. The Transponder detects this change and reads the difference in the reflected signal. From what I have gathered this is still considered to be passive.

RE: EN 61000-3-2:2000
This standard has been adopted by China and Japan. Japan has added a source impedance for the test setup, but it implies to me that this is a world-wide issue. Josh From: Rich Nute [mailto:ri...@sdd.hp.com] Sent: Monday, November 10, 2003 3:09 PM To: j...@jmwa.demon.co.uk Cc: emc-p...@majordomo.ieee.org Subject: Re: EN 61000-3-2:2000 Hi John: Some have questioned whether 61000-3-2 is even an EMC standard! If not, what do you think it is? I fall into the group that question whether 61000-3-2 is an EMC -- Electo-Magnetic Compatibility -- standard. The objective is to prevent reduction of peak voltage on the public supply mains (in Europe) due to rectifier and similar non-linear loads. The method chosen is to require all loads to be near- linear. I suppose this is a compatibility issue -- a compatibility between the source and the load. And, it is electrical. And, one can consider the harmonic content of the current waveform as being an emission from the product. But, this is purely a current emission. It is not measured with a receiver as are the other 61000-series emissions. Unlike radio-frequency emissions, incompatiblity affects no one but the electricity supplier. (Don't argue that other users on the public supply are affected; this is only true if the electricity supplier does nothing at his end.) Non-linear current is not at all similar to the electo- magnetic emissions issue addressed by the other standards in the 61000-series. If harmonic currents are an EMC issue, then so, too, is x-radiation from cathode-ray tubes -- which is a MUCH closer fit. Why isn't x-radiation emission included in the 61000-series? Or laser emissions? Both of these are much better fits to the 61000-series than is a non-linear current. Lastly, this is a Euro-centric issue, not a world-wide issue. It shouldn't be in the IEC scheme. Next thing that will happen is that the 61000-series will include requirements against voltage emission (voltage on accessible parts) to achieve compatiblity with people to prevent electric shock! EMC!!! :-) 61000-3-2 should be a stand-alone standard. But, if it was a stand-alone standard, there would be no Directive behind it to enforce it. So, in a self-indulging mode, and by stretching the definition of EMC, 61000-3-2 is enforced by the EMC Directive. That is why it is an EMC standard.

You should be aware that there are 9 certifying bodies for CCC. CQC is only one of them. The agent you use will usually pick the body they like to work with.

RE: Mobile Power Cart
All, I want to thank everyone for the responses. It sounds pretty straight forward now. I will be verifying the compliance of the cart with a printer in place. I will use EN 60950 for safety, EN 55022, EN 55024, EN 61000-3-2, and EN 61000-3-3 for EMC. It also appears I may be using EN 60335-2-29 to verify the charger, but I am told ( I haven't seen it yet) that it is a recognized component. Thanks again, Josh Josh Wiseman EMC/Product Safety

On the contrary, UL, DEMKO and SGS all have publicized signed agreements with Gosstandart which (they claim) allow them to run tests on behalf of Gosstandart. The scope of the agreements include IEC 950 and EMC testing. I am not aware of whether any actual (read: successful) testing/data acceptance has been done by any of these agencies under the agreement. Be warned that written agreements among certifiers do not automatically result in a smooth pathway to certification. In my experience, even with less bureaucratic organizations than Gosstandart, an agreement to mutually accept test data does not actually turn into a viable service until the operational details have been worked out on both sides. (Cross training, inspections of facilities, corrolation testing, cross-auditing, report formats, review signatures, etc.) Although the publicizing and promotion of the agreement usually happens immediately upon signing, sorting out the morbid details can take years, using manufacturers as guinea pigs. This is ok, as long as the manufacturer understands what they are getting into. If you choose this route, you might want to ask the test lab about the track record of the agreement, and whether you will be part of the fleshing out period.

(cleaning mating surfaces, chassis, ) One must take care to separate fact from opinions. Mixing metals as you mention is NOT necessarily a sure way to promote corrosion. Yes, steel against aluminum us not good practice since they are far enough apart on the electromotive series that they will act as a local battery (in the presence of an electrolyte such as salt water), and the aluminum will corrode. Another bad pair is aluminum against copper alloys. But in a dry environment, no problem can occur since no moisture is present. Galvanic corrosion without the presence of an electrolyte is impossible. Other metal combinations are also problematic such as aluminum against zinc plated or galvanized steel (or zinc plated anything). Cadmium plated steel against aluminum is generally considered an acceptable combination, as is 300-series stainless steel against most metals. 300-series stainless (especially type 316) is considered relatively passive. One must simply choose the metal pairs carefully, taking into account the environment, and if necessary making sure they are sufficiently close in voltage potential to each other on the electromotive scale.

(cleaning mating surfaces, chassis, ) David, You mention that you have a Steel and Aluminium to content with. My opinion about mixing metal parts in an assembly (chassis) is a sure way of promoting corrosion, especially if the installation is in a humid environment. If you want the chassis to be a reliable electrostatic shield do not have panels that are made with different metal bolted to the 'frame' or chassis. Under some codes this is a 'No Go' area. BTW, I assume that you must be working with a small box, otherwise you would need much more than a 'rubber eraser' to clean the mating surfaces. All equipment metalwork should be electrically bonded in a manner which does not rely on 'hopeful' electrical conduction through anti-corrosive treatment like anodised aluminium and paint. Careful attention to the assembly process will weed out things like ball-bearings races, nylon runners and coasters, or other insulating materials. Conduction through painted panels should not be dependent on the gripping action of star washers. The design should be such that no currents flows in any part of the metal work. The objective is to ensure that any part of the metalwork can be relied upon as an effective electrostatic screen and not the reverse, a radiator.

Indeed, it refers to compliance with all directives relevant to the product, so a teddy bear will be CE marked if it meets the requirements of the toy directive and all relevant safety directives. Pressure vessels will have to meet the requirements of the pressure directive and so on, and if any product crosses boundaries, it has to meet all the applicable directives. However, the CE mark is a declaration of conformity and you can self certify. This means I can disappear into my garage for a few weeks and emerge with a CE marked product - and it would be perfectly legal - as long as the declaration is true i.e. I have done what needs to be done to prove compliance, and one way to do this would be to test to applicable harmonised standards. Validity of self certification may change in due course but at the moment, that is how it is. I like Chris Maxwell's spin on the meaning of CE, and it would be true if every firm made a distinction between the compliance engineer and the designer. In all the companies I have worked for - we do it all i.e. the designer designs to spec, takes the product through type approval tests, then through precompliance and then through full compliance. So the electronics designers are responsible for meeting all the applicable directives (EMC, electrical safety) and functional type approval and they do so by product proving and EMC testing the product themselves - to the applicable standard. They are also responsible for the technical documentation for the electrical aspects of the product. The mechanical engineers and hydraulics engineers do likewise and when it's all done, the fall guy (engineering director) puts his signature on the declaration of conformity. What this means is that if the declaration should subsequently be proven false, he is the one who goes to the gallows. Wait a minute! I used to think everyone worked that way, but I get the feeling I may be doing too much! That does it!

EN 61000-3-3
Hi all, I have recently heard of a requirement in the Flicker standard for In Rush current measurements. My understanding of the test is that the EUT is manually turned on and off 24 times. During these times dmax is measured. You then take the highest and lowest readings and throw them out. You then average the remaining 22 readings. This has been posed to me from a customer and I can not find any supporting information other than the fact that some test equipment manufacturers are beginning to implement the testing capability in their systems. Any information on this would be greatly appreciated. Thanks in advance for all the help. Regards, Josh

[mailto:masse...@ems-t.com] Sent: Monday, June 11, 2001 1:55 PM To: 'IEEE Forum' Subject: New laser standards Hello Group - Can anyone direct me to an informative article, link, etc., that summarizes the impact of Amendment 2 to IEC 60825-1, released in January of this year ? I've reviewed the amendment and am aware of the basic differences it brings in classification, but it sure would be nice to have a synopsis of all the changes. Also, does anyone know how soon the changes will be incorporated into a new release of the standard ? The IEC website does not list a target date for release, although the status of edition 1.2 shows it being out for printing since early May. Also, CDRH Laser Notice # 50, published late May, harmonizes, to some degree, 21CFR to the IEC 60825-1 standard, with the notable exception of production line test requirments, record keeping, and some product marking requirements, which are being kept by the CDRH. Has anyone heard if the CDRH product report formats will be changed ? I'm thinking an IEC-60825-1 report, with US national deviations, if you will, may be acceptable to the CDRH at some point in the future, in lieu of their existing published report format. Of greater concern is the lack of a specified transition period and mandatory compliance dates in either standard (at least I can't find them). Will existing laser classifications be grandfathered? When will laser product manufacturers be required to label products according to the new classifications? I can see the new classifications causing much confusion among customers, who may have, say, Class2 laser products, then buying additional units of the same product, which might be labeled as Class 2M, for instance.

Since the people who designed the instrument are long gone, some of my collegues have asked me if this resistor could be a safety feature. I can't think of any way this resistor would help the safety of the instrument. I did read through the safety test report; and I found no reference to this resistor being required. All it does is provide a constant drain on the battery (reducing battery life). It has been suggested to me that some designers put resistors across batteries to reduce the electrical noise in a product. To me a capacitor would be better for this because it wouldn't drain the battery while it was filtering. Even so, isn't a battery the ultimate capacitor? I'm just drawing a blank why anyone would do this. I'd love to recommend that we pull this resistor out because it's a pain to solder and it affects battery life.

Here are some things I think I know regarding generic ITE. I am unaware of any safety/EMC certification requirements in Hong Kong. Note that Hong Kong is now officially part of the People's Republic of China, but operates a bit apart from mainland PRC. The IEC listed CB reviewing body for the PRC is the CCEE, which has the authority to issue the Great Wall mark based on compliance to GB4943-1995 (IEC 60950 in Chinese). However, the CCEE mark is primarily required for electrical equipment made in China for sale in China, i.e. an internal safety mark.. All imported ITE must obtain the CCIB certification and mark to GB4943-1995 and GB9254-1998 (EMC, CISPR 22). A CB Test Report is accepted and preferred, but China labs perform the EMC tests for CCIB. A key requirement is an initial factory inspection by SAIQ/CCIB personnel. Depending on the location of your factory, this can be a schedule problem as they cannot afford the time to fly to the U.S. for a single inspection. Our factory was one of seven being inspected in 1998. There are some other peripheral requirements for consumer ITE, e.g. user manual in simplified Chinese. The PRC does not wish to be westernized, and prefers that packaging, documentation, etc. be in Chinese. I hope this helps.

RE: Why routine hipot is required.
Mike, I have had instances on the manufacturing line were the unit would fail the Hipot or Ground Bond test. The same holds true. The power supply is an approved part and was tested by the power supply house. With this information alone I would recommend doing the tests on the end product. Josh -Original Message- From: Mike Morrow [mailto:mi...@ucentric.com] Sent: Thursday, August 31, 2000 10:40 AM To: EMC Society Subject: Why routine hipot is required. I've been asked why a routine hipot test is required on an end assembly computer when it uses a Listed power supply that has already been hipot tested. So far I don't like the way I've worded my response. Basically what I've said is that a power supply is approved as a component. The end safety of the device depends on the installation. Can anyone add some more beef to this statement. Thanks.

Harmonics
Hi Group, A question has been asked of me regarding equipment that does not comply with EN 61000-3-2. Our equipment does not comply today, there is however a plan to introduce a new power supply to the product that does comply. The new unit has been tested. Management does not want to spend the money to implement this until necessary. (Same old story.) They have asked me to find out if one of our European distributors buys some product and it is in country before 12/31/00. What is the implications of them selling it after the first of the year in that country or any other part of the EU. Joshua Wiseman Product Safety/EMC
Harmonics and Flicker
Hi group, I have a question regarding Harmonics and Flicker of equipment greater than 16A. I have a supplier who wants to know if he has to comply. I of coarse led him in the right direction. My question though is what is the DOW or DOC of the newer standards: 61000-3-4 1000-3-5 I have asked labs and anyone else I can think of short of buying the standard. I will be buying it in the near future, but I would appreciate some guidance before then. Thanks in advance for the response.

I haven't been able to establish what is meant by Steady Conditions. I was told once by a rep. of a large safety company that it meant no more than a 1 deg. C rise in 15 minute period.

If anybody has a good definition of Steady Conditions and can point it out to me in UL1950 or in the PAGs, I would appreciate it. Daniel W.

RE: Global Engineering Change Process
Joe, Here at my company we use a program by the name of Agile. All ECO's, CCR's, Deviation's, Stop Ships, and so on are done through this program. The nice part about the program is that it is pretty versatile in that every change goes through the same group or board. It doesn't matter if the change is originated in the here in Ca., Singapore, or Holland. You can import drawing files from Pro E or a scanned image from a basic photo editor. All spec sheets, drawings, BOM redlines are added to the change and submitted to the board for review. Once implemented the Quality department has the responsibility of ensuring proper installation of the most current parts and Revs. It has worked well for the last 5 years or so.

RE: EN55022:1995 vs EN55022:1998
Cyril, In reading the new standard one thing that caught my eyes is that Telecommunication ports are re-defined. In this case a Telecommunications is anything that hooks to a network i.e. LAN/WAN environments. For that reason alone I have to test to the new portion of the standard, but I am not required to do so in the immunity portion of testing. My two cents...
