RE: Safety regulations
Bonjour Benoit: The devil is in the details. If the Card Cage is LISTED and it has a particular model number and now you add data cards to it and you sell the Card Cage under a different model numbers ( that will vary depending upon your various configurations ) the Card Cage then becomes no longer LISTED. You have to advise UL and have them include all of the new model numbers in the LISTING and provide info as to what that changes are.*and that will cost you about 800 US DOLLARS.

Can he put that on the market without having to re-list the new product as long as the markings on the power supply are still visible from outside the box? If the card cage is LISTED, then probably okay. If a product is LISTED, then it meets safety requirements for its intended purpose, namely a card cage with cards provided by another entity. Be careful that the card cage is LISTED rather than RECOGNIZED. If RECOGNIZED, then it is intended as a part of some host equipment, and the host equipment will need to be independently certified (LISTED). If the card cage is LISTED, and you put another name on it to make it look like a different product, or make it look like another manufacturer, then you will need to get a COMPLEMENTARY LISTING. This is where t he certification house lists both you and the card cage as manufacturers, and that the card cage manufacturer is the actual manufacturer. I hope this answers your question.

RE: ETL vs. UL
All, I know that most of the general population is aware of the UL mark applied to almost all appliances, equipment, etc, and that UL is the accepted safety marked to have on a company's product, at least here in the USA . However, because of UL's reduction in staff ( which is causing huge delays in getting service ), and because of some of their harsh treatment of their clients , I am sure a number of UL's past clients have successfully found alternative safety labs to submit their products to. I am investigation alternative safety labs ,ETL is a lab that keeps popping up as an alternative to UL. Would anyone please offer me any pros or cons in dealing with ETL ( I already know the Pros and Cons of UL ) ? Also , if you would or could inform me of the level of acceptance throughout the country that ETL has, I would also appreciated that information. I am already very much aware of the broad based acceptance of UL as THE SAFETY INSTUTION to go to.

It is the standard for evaluation of a piece of ITE equipment for electric shock, energy hazards, fire hazards, radiation hazards, chemical hazards, and mechanical hazards. 60529 (IEC or EN) is the ingress protection standard. It is a test standard which enclosures are tested for the extent to which they protect against personnel access, dust access, and water access in various environmental conditions. They are not comparable, they are complementary. Say you've got an outdoor computer.

The OATS must comply with the requirements of ANSI C63.4 and the correlation measurements must be performed per C63.4.

We have going to an outside testing house for FCC verification and wish now to do our own verification. * WHAT I AM LOOKING FOR IS THE Step by Step procedure for calculating and performing Data Correlation between a GTEM Cell and OATS ! ** In researching what has to be done to accomplish this task, I have gathered the following information... 1)I Do NOT have to submit the correlated data to the FCC 2) The test does require that we do three ( 3 ) separate setups and break down when we start to collect data. 3) The correlation between a GTEM and an OATS must be performed with a device of the type for which you wish to qualify the GTEM. The OATS must comply with the requirements of ANSI C63.4 and the correlation measurements must be performed per C63.4. The same measuring instruments should ( but is not necessary )be used at both test locations.

RE: Apples and Oranges of FCC Data Correlation / Verification
Ken, I guess I stand corrected ! I spoke with Thomas Philips of the FCC, he gave me addition info. I had asked the same question to him that I had asking the group. Apparently I was mixing Apples with Oranges. With our products we are dealing (Information Equipment ) Class A part 15 sub part B ,etc. We are looking to self VERIFY but NOT to have our product Certified. My understanding in speaking to Thomas Phillips is that when you are Certifying your products and you are using a GTEM Cell to do so , that is only then that you take your test product to the OATS and perform this back and forth between OATS and GTEM ( three (3) times ) . You then submit this data to the FCC and show your method of data correlation. My understanding is that this is only to be once ! This is NOT what I am actually looking for. I am looking to FCC Verify .

But I made the following extra recommendation which I believe is absolutely essential. If the EUT has any cables attached to it, power or otherwise, then cable common mode currents must be separately controlled, because the algorithm which correlates GTEM potentials and OATS field intensities assumes the EUT is a point source of radiation. This is true whether you use a software algorithm or a completely empirical technique such as a standard site source (comb generator driving a stub antenna).The cables are a distributed source of radiation and cannot be properly laid out in the GTEM cell (even in my customer's cell, in which I could stand up and walk around). -- From: Reginald Henry rhe...@vicon-cctv.com To: emc-p...@majordomo.ieee.org Subject: GTEM Cell / FCC Data Correlation Date: Wed, Aug 14, 2002, 10:43 AM Group, I have a GTEM Cell that I use for CE Emission and Immunity testing.

RE: RJ45 filtered connector
Ron, Thank you for your assistance in getting me closer to completing my task at hand ! I really like the different alternative solutions that you have provided for me. I also tend to agree with you, in terms of the speeds ( Category 3 aka ... Cat 3 for 10 Base T, Category 5 aka Cat 5 for 100Base T)I will be working with, does not lend itself well to traverse thru mixed connectors ( terminations , DB connectors, etc ). My understanding in the little education that I have gotten since I first started investigating these connectors,is that the degree in which the wires are twisted ( number of twist per xxx distance )will make all the difference in the world if the information (data) gets thru or not. Once again thanks a million. PS. I loved your comment about the flames... very appropriate !

To that end, I will offer some suggestions: 1. Talk to chamber manufacturers. I am quite sure that they would know about such a connector if one exists. 2. A bulkhead mounted DB25 connector might work. These can come filtered, however, the filtering involved should not impact the communication speeds you will be working with. To connect to standard ethernet cables, use 2x(DB25-RJ45) adapters (1 inside 1 outside). The whole thing would be connected as Outside Cable - Adapter - Bulkhead DB Connector - Adapter - Inside Cable. These adapters are quite common and shouldn't need to be filtered as the DB connectors would do that and if extra filtering is needed, a simple clip-on ferrite might be all that's needed (the ferrite might even be put inside the adapter backshell). And, the DB25 connector might be used for other interfaces during testing, as well. 3. You shouldn't need any connector if your EMC chamber has a ventilation opening. Just fit a cable thru the opening and put enough ferrite around the cable (inside and outside) to suppress any common mode interference. These suggestions are intended to get all those neurons firing to think of some connector alternatives to the one you're seeking. I hope this helps. Comments anyone?
