RE: OATs enclosure interference
Bonjour, I have seen some of these in the course of my visits to EMC laboratories and one of the very good reason to have the door facing the antenna is that when you will have to do the VNSA it will be much easier to align the antennas, regardless of the way you actually perform your measurements (with open or closed doors). On the other hand you will have to decide whether this is more important for you than seeing the setup while testing, one way to do both is by the use of cameras (to see the setup while testing) or having very good marking floor lines from the turntable to the mast. But as it has been point out by others having a dielectric in the path of the measurement can create problems as well, may be a test done on the shelter before it will be secured to the floor would be a good idea if you choose to orient the opening to your control room. May be an orientation of the control room in the path of the setup to antenna could also be considered. Also remember that contamination of the shelter must also be taken into account.

A link to the enclosure link can be seen below. My question is does the door opening to the dome need to be facing the antenna mast while tests are running so that there is no fiberglass between the DUT and the antenna. If we could we would like the door facing the control room so we can see the turntable. Any thoughts would be appreciated.

RE: ICES -003 approval for FCC DoC product
Bonjour à Tous, For test site registration, you only have to do that with Industry Canada if you test transmitters. For non-intentional radiators you don't need to register your site. Also ICES-003 is a regulatory document; it is not a testing procedure. CAN/CSA CISPR 22 is the testing standard but if you have a test report that is written around CISPR 22 it would be acceptable for Industry Canada. Since there is no requirement in Canada that the laboratory has to be accredited, the MRA requirements for non-intentional radiators testing do not apply as it would be the case for a Declaration of Conformity according to the FCC regulations.

EMC Chapter of Montreal, June meeting
== IEEE Montréal - IEEE Electromagnetic Compatibility Society présentation (in English) : Antenna Behavior and Use - (What Really goes on during a test?!) Colin E. Brench Hewlett-Packard IEEE EMC Society Distinguished Lecturer == List-Post: emc-pstc@listserv.ieee.org Date: Mercredi 5 Juin / Wednesday June 5, 2002 19h00 Place: CRIQ 8475, rue Christophe-Colomb Montréal $$: Gratuit / This event is free to all. For future events IEEE membership may be required. To join online takes about 10 minutes : http://www.ieee.org/membership/join/ ABSTRACT Measurements made to show compliance to the EMC regulatory limits for radiated emissions require the use of antennas. Unfortunately there is a disconnect between the ways the antennas are designed, used and calibrated. This is further confused by the international requirements that must be met when both qualifying an EMC test site and the theoretical models which still have their own inaccuracies. Most of the difficulties arise from the size of the antennas, which at lower frequencies are comparable to the test geometry dimensions. When making any measurement it is an essential goal that the measurement device does not alter the parameter being measured. This is very difficult to achieve during EMC testing and so there is an additional source of uncertainty hat needs to be evaluated and considered. This presentation explores the history of measurement techniques, looks at the magnitude of the errors introduced, and shows how through the use of computational techniques this problem is slowly being addressed. To help explain the issues, the behaviors of a number of different antennas are explored in the EMC test environment. SPEAKER Colin Brench has been working for Digital Equipment Corp., Compaq Computer Corporation, and now Hewlett-Packard Company for 16 years, where he is a Principal Member of the Technical Staff. He has responsibility for EMC product design, and the development of EMC modeling capabilities in the High Performance Server Division. Colin has been particularly active in the area of antenna and shielding behavior since the early 1970's. Colin has presented numerous EMC training classes that embrace a broad range of topics ranging from microprocessor packaging, through printed circuit module issues, to system design and shielding. In many of these classes explanations are clarified with a combination of simulations and data from measurements. Colin is a co-author of the book, EMI/EMC Computational Modeling Handbook (Kluwer Academic, 2nd Edition 2001), and has authored well over 20 technical papers and articles. In addition, he holds ten patents for various methods of EMI control. He is a NARTE certified EMC Engineer, a member of the Applied Computational Electromagnetics Society (ACES) and the IEEE EMC Society. He is active in the IEEE EMCS TC-9 and ANSI ASC63 SC-1 committees. In March of 2001, Colin was appointed a Distinguished Lecturer for the IEEE EMC Society.

== IEEE Montréal - IEEE Electromagnetic Compatibility Society présentation (in English) : Wireless Healthcare Issues Tomas Pavlasek, McGill University, Introduction Donald Davis, McGill University, Volumetric 1.9-GHz fields in a hospital: EMC implications Bernard Segal, McGill University, Risk of patient injury due to EMI: Estimation minimization == List-Post: emc-pstc@listserv.ieee.org Date: Mardi 21 mai / Tuesday May 21, 2002 19h00 Place: CRIQ 8475, rue Christophe-Colomb Montréal $$: Gratuit / This event is free to all. For future events IEEE membership may be required. To join online takes about 10 minutes : http://www.ieee.org/membership/join/ ABSTRACT Mr. Davis Talk: The current draft of the next medical-equipment EMC standard, IEC 60601-1-2, will recommend usage of free-space minimal separations (between RF sources of given power and medical devices of given immunity) to minimize EMI malfunction of medical equipment. We have previously reported that such separations were useful in most hospital corridors, but such reports were based on mid-corridor measurements. We now describe preliminary three-dimensional 1.9-GHz extensions of these reports. We found that mid-corridor path loss was less than that at corridor walls. Path loss near floors was much less then that at higher locations. Because medical devices are rarely placed on the floor, our previously reported minimum-separation recommendations are still likely to apply at most corridor locations. Dr. Segal Talk: Healthcare needs wireless informatics. To implement this need safely, hospitals require suitable wireless-EMC policies. However, most lack such policies, partly because some are unsure that patients really risk being injured by EMI malfunctions. Factors affecting this risk are critically overviewed, specifically the probabilities (1) that RF sources operate at given locations, (2) that fields from such sources propagate to a susceptible medical device, (3) that this device malfunctions, and (4) that the malfunction causes patient injury. Only qualitative estimates of the resultant overall EMI-injury risk are possible. This risk is probably very small but must be minimized. Ways to do so are critically overviewed. Both papers have been presented during the 2001 IEEE International Symposium on EMC, Montréal, August 13 to 17, 2001 SPEAKERS Dr. Pavlasek: Tom Pavlasek is an Emeritus Professor in Electrical and Computer Engineering at McGill University. His research interests include scattering-diffraction of electromagnetic and acoustic waves; near-field behaviour of antennas; and numerical modeling of complex antenna systems. He is a pioneer in electromagnetic compatibility and electromagnetic environment research. Mr. Davis: Don Davis is a PhD candidate at McGill University in the department of Electrical and Computer Engineering. His research interests include indoor and outdoor propagation of electromagnetic fields from 100 to 3000 MHz. Dr. Segal: Bernard Segal is a highly-inter-disciplinary Research Engineer. He is an Associate Professor in the Ear-Nose-Throat Department of McGill University, with several cross appointments (Biomedical Engineering; Electrical Computer Engineering; Physiology). He is the Director of Research in the Ear-Nose-Throat Department of the Jewish General Hospital. He created and heads a multi-disciplinary cross-Canada team, The McGill Biomedical Engineering Group on Electromagnetic Compatibility. He heads a Canada-US Task Force on Electromagnetic Compatibility in Health Care. He has organized over 25 national and international conferences, workshops and teaching sessions on Healthcare Electromagnetic Compatibility. Dr Segal's goal is to bring people from various fields together so that they can resolve electromagnetic compatibility issues in health care.

RE: CNS Standards
Bonjour de Montreal, Just a few comment about BSMI, MRAs and testing. The APEC TEL MRA was sign by the DGT in Taiwan, thus allowing foreign testing lab to the EMC on telecom equipment only. The extension, in USA, of this MRA to Information Technology Equipment was negotiated separately by the FCC (actually by the means of an exchange of letters between trade office in Washington and Taipei for political reasons). The terms used in those letters states that Designated US based lab data would be recognized by BSMI for tests performed on US products. In fact, Us tests labs can only test US products. This situation made me test in Taiwan for the last two years, waiting for the Taiwan Foreign affairs to sign the same type of agreement with Canada. On the other hand, South-Korea was just (see attachment) update their Annex 1 of the APEC Tel MRA, including all EMI and EMS test. So, accredited tests labs, even American ones, if they have their scope modified to include the South-Korean requirements, could be designated. I just received mine a few days ago.

I'm sure it has the usual disclaimers on it warning that in the event of a conflict between the original and the translation, the original Chinese prevails, though. Thanks for your post detailing the MRAs. I think it helps make some sense out of it for those who aren't following it regularly. About the in-country testing required note on our web site, that's actually intended to refer to telecom testing. BSMI has recognized EMC test reports from designated labs even before the APEC TEL MRA, and DGT adopted this practice when they began evaluating EMC compliance on telecom equipment two years ago. On the telecom front, Taiwan has been ready for some time to move forward with the US on Phase I and more recently Phase II of the MRA. It's just a matter of designating labs outside of Taiwan. As far as I know, the only lab designated for any standard besides EMC is CCS. For wire line telecom, until there are labs designated outside of Taiwan to test to the standard that applies to a product, the practical advice is that it's got to be tested (for telecom) in-country.

Hi John, A possible solution would be to use an infrared non-contact thermometer. They measure temperature essentially by pointing them at the object of interest. They have a few drawbacks that I know of: 1. You need to have visual access to the part or surface of interest. 2. You need to account for spot size since its detector essentially integrates all of the infrared in its field of view. The spot size changes with distance from the thermometer to the surface of interest. 3. If you are trying to graph temperature over time: you can't just glue it in place and hook it to a data logger.

John, In my company, I often run into this problem and a non-contact or infrared thermometer is not always pratical. Like you, I also had to resort to momentary turn off to get accurate readings. In one instance, I had magentic fields strong enough to cause damage to the instrument. There are several things you can do and not all of these are always necessary. 1) I exclusively use T type thermocouple wire because it has no ferrous content and the effective temperature range more closely brackets the temperatures I am interested in. The reason for non-ferrous wire is strong magnetic fields not only induce erroneous readings, but they also cause heating of the thermocouple itself. In the past I typically saw this problem with the K J types. Simply doing a momentary turn-off does not correct this problem as the wire takes some descrete time to cool off and after a point you don't know if you device under test is cooling as well. The problem is that I've never found a handheld meter that accepts T type wire. 2) The next thing I do is insure the thermocouple conductors are not separated, keeping loop area small. Twisting is ideal if you can do this without damaging to the welded tip. Ideally you should be able to weld your own. 3) If possible, try to orient thermocouple wires to avoid 'cutting' flux lines. 4) Try using ferrite beads to knock down any common-mode RF induced on the wire and being conducted into the instrument. The readings you are interested in are essentially DC. 5) If you are still having troubles, construct a Faraday shield by wrapping with copper foil. Grounding the shield may be helpful. The shield needs to fully enclose the thermocouple bead and surround the wires for some distance, far enough to exit the area where the fields are. Be sure the copper foil is insulated inside and out. Note, readings may take a little longer. 6) Finally, if all else fails, you can resort to the resistance method described in IEC 61558-1 (fomerly IEC 60742) clause 14.2. This takes a milli-Ohm meter. -doug --- Douglas E. Powell, Compliance Engineer Advanced Energy Industries, Inc.

RE: Too small to print Fcc Verification label!!!
Bonjour de Montreal, It all depends of the procedure you used for your product : If it is a Class B digital device using the, now obsolete, certification process, you have to put at a minimum the FCC ID of your granted certificate. The only way it could be used now is by the mean of a permissive change procedure. If it is a Class B digital device using the Declaration of Conformity (DOC) procedure, then at a minimum the FCC logo (see attachment) has to be on the device, all other information in the user’s manual. If it is a Class A digital device, using a verification procedure, this is where you have a problem because you don’t have an FCC ID and the FCC logo is reserved to the DOCs, my suggestion in that case would be to state in writing, FCC Class A and put all the rest of the information in the user’s manual.

RE: FCC + FCC = FCC?
Bonjour de Montréal, The FCC regulation allows the construction and marking (see FCC2.jpg) of PC when they are assembled using separately authorized components. Here are a copies of sections of the FCC regulation 15.19 Labelling requirements. (a) In addition to the requirements in Part 2 of this chapter, a device subject to certification or verification shall be labelled as follows: (1) Receivers associated with the operation of a licensed radio service, e.g., FM broadcast under Part 73 of this chapter, land mobile operation under Part 90, etc., shall bear the following statement in a conspicuous location on the device: This device complies with Part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference. (2) A stand-alone cable input selector switch, shall bear the following statement in a conspicuous location on the device: This device is verified to comply with Part 15 of the FCC Rules for use with cable television service. (3) All other devices shall bear the following statement in a conspicuous location on the device: This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. (4) Where a device is constructed in two or more sections connected by wires and marketed together, the statement specified under paragraph (a) of this section is required to be affixed only to the main control unit. (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. (b) Products subject to authorization under a Declaration of Conformity shall be labelled as follows: (1) The label shall be located in a conspicuous location on the device and shall contain the unique identification described in §2.1074 of this chapter and the following logo: (i) If the product is authorized based on testing of the product or system; or See FCC1.jpg (ii) If a personal computer is authorized based on assembly using separately authorized components, in accordance with §15.101(c)(2) or (c)(3), and the resulting product is not separately tested: SEE FCC2.jpg2 Copy of 15.101 (c) Personal computers shall be authorized in accordance with one of the following methods: (2) The personal computer is authorized under a Declaration of Conformity or a grant of certification, and the CPU board or power supply in that computer is replaced with a CPU board or power supply that has been separately authorized under a Declaration of Conformity or a grant of certification; or (3) The CPU board and power supply used in the assembly of a personal computer have been separately authorized under a Declaration of Conformity or a grant of certification; and Hope this help Regards, == Benoît Nadeau, ing., M.ing.

I think this raises a parallel issue of testing methodology versus practical application. Many devices/ boards/ add ons are tested with minimal connecting attachments i.e. conductors, other than those to power the devie and those required to make the measurement. When separate devices such as those mentioned are placed into actual service , the systems themselves become attached to conductors with sizeable electrical lengths.

Re: BCIQ Taiwan
Bonjour de Montréal, I can share with you the latest experience I have with BSMI. First, KTL is the only one in North America to be accredited for Korean regulations, not Taiwan. In fact, they are not accredited for BSMI as any other Canadian Laboratory until Canada sign a Mutual Recognition Agreement (MRA) with Taiwan. 2) The USA listed laboratories in the BSMI site could only test American products. So Canadian or Israeli manufacturer could not use this avenue to get the BSMI approval. This have been confirm by the BSMI Official and the FCC. The wording of their letter of agreement clearly states that. 3) For other countries laboratories listed on the BSMI Web site (from Germany, UK the Netherlands and Singapore), I don't know if they have the same constraints, but according to the conversations we had with BSMI officials, they possibly will lose their accreditation since the BSMI wants to follow the MRA route for any laboratory outside Taiwan. Since they are still listed in the BSMI Web site, I presumed that this is still to come and that they are still active to deliver test reports but may be for their own market. Bad news for the European countries, Taiwan does not recognize the European union so every country has to get in line to negotiated a separate MRA. 4) The only route right now for any other countries is to test in Taiwan. 5) Even if you test anywhere, you still have to produce a test report that is going to be examined by BSMI. The experience we got is that their are very specific in the amount of detail that they want in the report. If you were familiar with the old FCC certification process, you have top follow that but with a lot more details. For instance they like to see an actual copy of the intended label or at least the exact dimensions. I hope that this information will be useful for you.

Bonjour de Montreal, I'm also very skeptical about this since the tendency is Europe is to de-regulate.

Last October we completed our own full compliance lab for EN 61326 as well, an investment at that time of about 250k USD (not counting equipment we already had, about 100k worth). The lab has already paid for itself (this week in fact). Though we'd be pretty irate to see it reduced to a mere precompliance lab: we're kinda proud of our solid aluminum 10 m OATS and the thousands of pre-drilled holes and self-tapping screws spaced every 5.1 cm (2 inches) we used to build it. I suspect the SLIM comment was taken out of context. I think we can all imagine the many and political, financial, trade effects and their very serious consequences, such as it might kill the US/EU MRA - if I had a vote on the matter It'd absolutely convince industry and corporate leaders that the regulatory world had gone insane, something they already suspect. Regards, Eric Lifsey Compliance Manager National Instruments Please respond to Gail Birdsall gbird...@hach.com To: emc-p...@majordomo.ieee.org cc:(bcc: Eric Lifsey/AUS/NIC) Subject: SLIM Greetings Colleagues, We heard form a reliable source who attended the June meeting of the EU Commission on the SLIM Initiative, of discussions to limit the certification of product family EMC standards to notified (competent?) bodies. If this is true, it would effectively close the self testing and certification route for manufacturers required to test to product specific EMC Standards. We understand that, possibly the Generic Standards route would still be left open to manufacturers who wish to self declare. As you all know, currently where product specific standards exist, they supercede the Generic Standards. My company has spent hundreds of thousand of dollars on EMC equipment and facilities to enable us to test and self declare our products. We originally tested and certified to the Generic Emissions Immunity Standards, but have recently switched to EN61326:97 AM1:98. If the above action is true, it would seem to be big victory and financial windfall for EU test laboratories and designates. At the same time, it would be a terrible blow to both EU and US manufacturers who invested heavily in test capability to self declare their products. Does anyone know of the validity of the SLIM action to require testing of product specific standards such as EN 61326 by Notified bodies? It has always been my understanding that the SLIM Initiative was to make things easier not more complicated and expensive by requiring 3rd party testing. Can anyone tell me if it is truly the plan of the EU Commission to take away self testing and declaration? We have heard that the new EMC Directive incorporating the SLIM Initiative recommendations may be out as early as the end of the year.

The only problem is that the BS EN55022:1998 that I order through Global Engineering Documents Service in Denver Colorado does not have this paragraph, only a blank space line a vertical line at the left end side. Regards, At 12:55 PM 5/9/2000 -0600, Wagner, John P (John) wrote: When EN55022 was adopted, there were several common technical modifications to CISPR 22. One of those changes was to delete subclauses 8.2.1, 8.2.2 and 8.2.3. In the EN, the following paragraph was added to 8.2 The operational conditions of the EUT shall be determined by the manufacturer according to the typical use of the EUT wilth respect to the expected highest level of emission. The determined operational moed and the rationale for the conditions shall be stated in the test report. In other words, the Europeans did not buy the rationale of C63.4, possibly for good reasons. There are many terminals which are exclusively graphic and their host units simply cannot produce the conditions called for in CISPR 22. I think the EN makes sense.

RE: List of upcoming dates for standards
Hello Tania and all, It is true that CENELEC is not the only player in this. The date that each standard is Published in the Official Journal (O.J.) and the date that CENELEC adopted it are consecutive but the dead line date where you will have no choice to use this stnadard (or version of standard) will not differ. So the date that I'm am more interested is the Date of Withdraw (DOW) which appear in the listings. By the way, the search engine of CENELEC allows you to filter out those standards that have been published in the O.J. Just select PUB (Published in the OJEC) in the OJEC Status line.

RE: PCI Cards EMC Testing
Bonjour de Montreal, I've been doing this for years, the special requirement by the FCC is that when your Class A device is installed in a Class B computer and functioning, the overall system is considered Class A. But when your Class A board is installed and not functioning, the system still has to meet Class B. Your right about the fact that the board has to be tested in a typical system configuration (PC+Monitor+Keyboard+mouse+serial port device+parallel device+speakers+USB device, etc.. any different I/O port must be connected), the trick is to find peripherals that do not emit to much noise. Also you have to consider the different modes of operation to find the worst case (this is particularly troublesome for Graphic cards as the different resolutions are expanding all the time).

Re: 3 meter lab
Bonjour de Montreal, In an earlier life I used a spectrum analyser and a very special type of antenna to perform preliminary tests before getting to an OATS. The antenna is called a Bowtop antenna. It has 2 advantages 1) it is very small compare to usual (it has a cylinder shape of 17 cm diameter by 20 of height) and 2) it has a very flat Antenna Factors curve (+ 3, +/- 2.5dB from 30 to 650 MHz). The only small problem is that it is an active antenna, so you must recharge it or use it while connected to a power supply.

Re: EN50082-1:1997 EN55024
Bonjour de Montreal, In another life, I was working for a EMC Test lab and we always used the step by step procedure which was in the ESD Standard. We tested using this procedure for years and we did encounter some products who failed at low level ESD but had no problem at higher levels. We wondered what to conclude and had some hypothesis. 1) may be the current path was different at higher level or 2) Lower levels might have a slightly longer rise time which tends to produce more energy in the lower part of the frequency spectrum where the EUT was more sensible. Since the products were not staying in our hands for long we never had a chance to investigate further. Comments ? At 10:07 19-08-99 -0400, Jim Hulbert wrote: Immunity test standards EN50082-1:1997 and EN 55024 call out the basic standards EN61000-4-2 and EN61000-4-5 for ESD and Surge. EN61000-4-2, Section 5 starts out The preferential range of test levels for the ESD test is given in table 1. Testing shall also be satisfied at the lower levels given in table 1. EN61000-4-5, Section 5 contains similar wording. This is how we perform our compliance tests. We start at the lowest test voltage levels from the respective tables and step up to the test levels called out in EN50082-1/ EN55024 (or higher, depending on our own in-house product spec.) However, I have noticed that some test labs go straight to the levels called out in EN 50082-1/EN55024 and skip testing at the lower levels. I believe this approach is incorrect because it does not conform to the requirements of the basic standard and is simply not a complete test. As explained in EN61000-4-5, the non-linear current-voltage characteristics of the equipment under test should be considered and the test voltage should therefore be increased by steps up to the test level specified in the product standard or test plan. The same rationale applies to ESD testing where current-voltage characteristics are also non-linear. How do others approach these tests?

Computer classification in EN61000-3-3
Bonjour de Montreal, After a careful reading of EN61000-3-3, we tried to identify the testing conditions for computer devices and peripherals. Appendix A of the standard details the conditions for various household equipments. In section A.11 they specify that the test condition for consumer electronic devices is to measure only the dmax (maximum 4% of voltage variation). Are computer and peripheral considered as consumer electronic device ? If it is the case, then we don't need a flikermeter to meet the EN61000-3-3. Any comments ? -- Benoit Nadeau, ing. M.ing.

EN 55103-1 and EN 55103-2
Bonjour de Montreal, I just read in the ERA Safety and EMC Newsletter that Part 1 (emissions) and Part 2 (immunity) of EN 55103 Audio, video, audio-visual entertainment lighting control apparatus for professional use have been published in the Official Journal of the European Communities (OJ). According to the same source, the applicability of these new standards are well defined and rely on the primary function. It also seems that they are written to be consistent with other standards (such as EN 55022 for an PC add-on audio/video card such as Matrox is building) so multiple test and/or limits are not needed. Does anybody has some light to the basic standards, limits and acceptable criteria as defined in these standards ? Thank you in advance, -- Benoit Nadeau, ing. M.ing.

Declarations of Conformity and Markings
Bonjour de Montréal,
Matrox is building computer graphics and communications boards. In our efforts to meet every market place demands, we are presently looking at the issuing of Declarations of Conformities and markings of our products. This effort lead to questions for which I have to find answers. I already have some ideas of the response but I would like to discuss for matters with our group. Anyone have similar problems could gain or shared its way of doing things.
1) FCC (USA)
-Class B DOC Procedure
In that case it is quite clear that at least the new FCC logo, trade name and model should appear on the product. The question is the DOC must be supplied with every product either on a sheet or in the manual (preferably). This DOC must have the name of the responsible and a phone number but does it have to be actually signed (bear a signature) ? I look in Part 2 and Part 15 of the FCC Regulation and seen no specific demand for a signature.
2) Industry Canada (Canada)
Before 1995, the Canadian Government did accept the FCC statement for product entering Canada. But since then, they require a separate statement. There is a suggested text in the regulation but I've seen shorter version of this like : Complies with Canadian ICES-003 Class {*}. But most of the product I see around do not have this statement on the product. How do foreign company treat the Canadian market access ?
3) CE mark (European Countries)
The CE mark clearly has to be on the product. On the other hand the DOC is not required to be supplied with every product but has to be in every selling points within the European Market. In the CE Directive, there is no requirement for this declaration to be signed but it seems that National regulations requires this signature. Do you have any reference to this requirement ?
4) C-TICK Mark (Australia/New-Zealand)
The Down-Under market has also is own set of requirements where their special logo (C-TICK) must be on the product. However in that case, the importer or local representative must be identified by a special code next to the mark. Also, the original DOC and Compliance Reports must also be hold by this representative. No need to supply this declaration with every product.
5) VCCI (Japan)
For VCCI aligned its technical requirements to those of Europe last year (10 meters measurements, CISPR22 type, Class A and B). For Class B the equipment must bear the VCCI logo. For Class A, it is more complicated, a very long Japanese text has to be on the product (or a tag attached to the product). How do other Class A PC Card manufacturers deals with this ?
6) Korea
The Pacific countries are joining into the dance and Korea has, for what I know, the more stringent regulation. Not only they require the product to be tested by a Korean recognized test lab, but they require a test by year by product. They also have a special BIG logo that has be on the product.
7) Taïwan and Russia
These two last players are beginning to make wave. Luckily Taïwan signed an agreement with A2LA (our EMC lab Accreditor) which will possibly ease certification for this market. They do not seem to ask for a special logo and the control is done with the borders incoming papers. For Russia, I only have partial informations,
As one can see it is becoming quite complicated ( we even thought of wrapping our board with the numerous declarations and notes to we have to supply). I can not imagine when Singapore, Hong-Kong/China, Central and South-American countries and, why not, African countries will start to join the party.
Have a nice day anyway

Thank-you, Mark Urban Bonjour de Montreal, The Australian Spectrum Management Agency (SMA)is only asking for tests on the radiated side with a standard which is a replica of CISPR22. There is two main differences if you compare with the European requirements : (1) the laboratory used for the test must be accredited by their national laboratory assessor (NATA) or with some accredited body who have a Mutual Recognition Agreement with NATA (NIST/NVLAP or A2LA for USA, NAMAS for UK) and (2) the C-Tick mark is a trade mark protected by the SMA so you must ask for the permission to use it either by : - asking on a product by product base with an Australian registered Trademark/Tradename. Or - Have a local representative or distributor to hold it for you. He then have a Supplier code. Or - If you are an Australian Company, you can get a Australian Company Number (ACN). Or - By sending the registered name and address of the place of business of the Australian supplier.

First you will need a copy of the uudecode software utility easily download able from the Internet. After you go in the sub directory containing the funny characters. With your pointing device you highlight all the text from the words begin to end inclusively. You then use the copy function of the edit toolbox of your browser. You then have to open wordpad (or equivalent) and paste the characters in the wordpad area. You then have to save the file in the same directory where your uudecode utility is.
