RE: Unit and prefix capitalization
While this is belaboring the issue and, other than if I happen to run across any relevant standards references, it should be noted that most new and many updated standards we have to deal with are written using SI as the primary and sometimes only units. Also, in most scientific and engineering circles, SI units have been in use for decades, including NASA, medicine, general research, and the like. The few hold outs are business interests and general populations (particularly in the US). An anecdote: my dad worked in heavy construction and was an ardent objector to adoption of SI units in the US. As a creature set in his ways, it was just so much rigmarole and he didn't want to take the time to understand a linear measurement system that wasn't divided as he was inured. Yet for many years, he'd been setting grade using tenths of feet. Regards, Peter L.

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: NSA measurement and its uncertainty
KC, You don't mention what organization/standard that you are undergoing an audit with, I'll assume ISO 17025. I think you are correct that it would be very difficult if not impossible to meet the requirements when you add in uncertainty that takes into account the receiver, antennas, pre-amp and such. I think you can go about this two ways. The first would be ANSI C63.4-1992 section 5.4.6.2 it states. "The +/- 4 dB tolerance in 5.4.6.1 includes instrumentation calibration errors, measurement technique errors and errors due to site anomalies." The other way is if you are being audited to ISO 17025 section 5.4.6.2 Note 2. This may be a long shot. I am not an expert in ISO 17025 , but would mention it. I think that NSA would qualify as a "well-recognized test method". The last thing I would say is that there is currently no requirement by any governing body for uncertainty to be included in the NSA results. Technically the governing body is your customer, they define the method used and how the results are reported.

Re: NSA measurement and its uncertainty
Look at CISPR 16-1, Annex M for insight. This provides the basis for the +/- 4 dB. 3 of the 4 dB is already measurement uncertainty with the remaining 1 dB as site imperfections. However this MU does not include the signal source or the repeatibility of the test procedure.

I don't know the particulars, but that line is old. It is the Stoddart/Singer/Ailtech/Eaton/Tegam/ETS line.

Thanks a lot for all for immediate reply and valuable information. These information are well enough for me to take a decision. Best Regards Kuganesan - Original Message - From: Don Rhodes To: 'Kuganesan' Sent: Wednesday, July 17, 2002 1:27 AM Subject: RE: FCC report for our OEM customer Dear Kuganesan, I would suggest that you do not retest or change your EMC test reports for your OEM customer. Instead give your customer a letter on your company letter head which states that the two brands and model numbers in question are equivalent with respect to EMC. Give them this letter along with the test reports you have and that will protect them. This is in keeping with 47CFR 2.1073. We have used this policy for years at our company with our own OEM customers with no problem. See 47CFR 2.909 for responsibility on the DoC and who in this case should issue it.

Now, we have an OEM customer who want our product to be sold under their brand name. So, except the logo changes and label changes, the electronics and functionality remained unchanged. Please advise me, if the manufacturer's name in the FCC DoC remain unchanged, whether; 1) we can use the same FCC report to support our OEM product. OR 2) we need to get a new test report which include the photos of new Logo & Label. OR 3) we have to re-do all the tests and get the new test report. Thank you Best Regards Kuganesan
EMC Directive/Repaired Apparatus
To all, The following scenario is in regards to the EMC Directive. We are a manufacturer located in the US. We have various products that were placed on the EU market prior to the enforcement of the EMC Directive. We need to repair some of these products. The repairs will not modify the product to an "as new" piece of apparatus. We want to have the products repaired in the US. Questions: 1. Following the repairs, do we need to meet the requirements of the Directive? If so, why? 2. If not, how do we get the products back into the EU without the CE Marking? Hopefully someone has had some experience with this issue. All responses are appreciated.

RE: IEEE Conference Proceedings (2000 - 2001)
Dear All, The CD is a good idea for distributing the proceedings vis-à-vis a physical tome. There must be a great many number of discarded copies of the proceedings in previous years. My bit of disappointment is with the lack of page numbers on the documents found the 2001 EMCS CD and hope that this would not set a deviation from the practice of the 1999 and 2000 EMCS. It is a game of jigsaw puzzle assembling the pages from the 20 or so sets of papers that interest me along with another 40 or so sets which bears titles that may be of some interest. Darn good way of forcing any researcher to read everything. Every time a page was found to be missing or misplaced, the missing page had to be traced to the relevant files to be reprinted... This I should say is an enlightening game. On a lighter note it maybe that there should be some standards applied to this area. I suppose EN documentation standards are not acceptable in North America. :-) regards Tim Foo "Benoit Nadeau" To: "Wan Juang Foo" , Sent by: cc: owner-emc-pstc@majordo Subject: RE: IEEE Conference Proceedings (2000 - 2001) mo.ieee.org 07/16/02 09:29 PM Please respond to "Benoit Nadeau" Bonjour de Montreal, Let me point out a couple of things here. I was the Chairman for the 2001 Symposium. The reasons why CDs are used today are numerous for instance: 1- Most of the users (including myself) prefer CDs for its concentration of information and the search tools. 2- Since the IEEE EMC Society has the rare policy of sending the Symposium proceedings to every member worldwide (even if they do not go to the Symposium) and since a limited percentage of members actually go to the Symposium, each year, the Society saves thousand of dollars of shipping (especially to places like Singapore) so that every one gets a copy. By the way things are going, if every Symposium committee would have to send the printed version to everyone, this policy would have been dropped. 3- Many members who come to the Symposium find the books too heavy to carry and leave them in Hotel rooms and go away only with the CD. 4- If, like Mr. Foo, someone wants to get a completed printed version, collated and with page numbers, (and save on toner, paper and more important, time), he has many choices, participate to the Symposium (best way), ask someone he knows to purchase another copy on-site and convince him to carry this heavy weight (was 8 cm thick and 3.33 Kg, 40$ US in Montreal), ask someone who went to the Symposium and do not want the printed version anymore or wait after the Symposium and purchase this from the IEEE (a lot more money involved). 5- It is true that the 2001 Symposium papers on the CD ROM do not have any page number, but the purpose working with the CD is not to print every page and recreate the printed version but to find valuable information on a specific subject and only print the papers relating to this search. We never anticipated that someone would do that; this is the reason why we did not include page numbers in our CD ROM. I am sorry that some IEEE EMC Society members experienced problems with the CD ROM and the lack of page numbering of the 2001 Symposium CD but I hope this message will clarify the situation.
