RE: DC Power Short-circuit test GR-1089 Section 9.8.1

Eric, I assume you are aware of the published clarification on this subject published by Telcordia in December 1999. I suspect this might have led to your questions, which are very good. Rather than discuss your points specifically, I feel that simply covering the intent of this generic requirem

Sorry, I should have been more specific, regarding the # of discharges, we are working to EN 50082-1, IEC 801-2:1991/IEC 1000-4-2:1995. Best Regards, Bill Jacowleff VDO Control Systems Airpax Instruments 150 Knotter Drive Cheshire, CT 06410 Phone: 203 271-6394 FAX:203 271-6200 bjacowl...@vd

RE: EN 61000-4-2

Mr Jenson - I agree with Bill's input. When I do in house validation I will usually go to 10kV (or K) - 12kV for a test level. The standard we use is EN 60601-1-2 (medical electrical equipment) which states 3kV contact discharge and 8kV air discharge. These values are way too conservative for our

RE: China Packaging/Crating Requirements

Joe, There are different requirements depending on whether you export to or import from China. There is a January 1, 2000, requirement for all solid wood packaging materials made from softwoods (conifer) that are shipped from the US and Japan into China to be heat treated. Hard woods, plastic,

Re: China Packaging/Crating Requirements

I believe the problem is with wood crating and shipping materials coming out of China. The wood must be treated and certified to be free of insects, etc., so it is cheaper to fab metal pallets than use wood. - Original Message - From: Scott Douglas To: ; Sent: Monday, January 17, 2000

Chris, I am by no means an expert here as I have only been doing compliance about 2 years. Most of my experience is in I.T.E. i.e. UL 1950, IEC 950, etc. We have just recently started doing products that are tested under UL 3111-1, EN6101-1, IEC 1010-1, etc. I am basically going by what the stand

Dear Mr. Kim Boll Jensen: Well the answer to your question is 10 discharges to each point per polarity. A few other things to consider. It is also important to step through the voltages and not skip any. Is your internal test procedure going to be used as a supporting test for a DOC or is it

I recall having a problem with wood pallets once. The problem is that some place in the Pacific did not want wood from here unless is was certified to not have bugs (termites?) Can't recall any specifics, but do remember that we left it up to the freight forwarder to resolve. That is part of wha
