RE: EMC/RFI Gaskets

Hi Peter, Gaket material are covered as Recognized Plastics material. They are in the yellow books, just like regular plastics material (QMFZ2). Some gasket material were Recognized under that QMFZ2 category, but there is also a special category (Q) that covers gaskets in particular. I

RE: Surge Test Performance Criterion

those criterion from similar product standards to your product can indirectly cover expectations of your customer. As for criterion B, I would say no, shut down for ten minutes and then recoverable is criterion C. Hope this helps. Regards, Robert Tims Compliance Engineer Ericsson Messaging Systems Inc

RE: WEEE Directive

, this is a good option for non-halogen applications, just more expensive with less applications than PVC. Good Luck. If you need any more info, you can contact me directly. Regards, Robert Tims Compliance Engineer Ericsson Messaging Systems Inc. -Original Message- From: Rich Nute [SMTP:ri

Re: Is there any correlation between VW-1 wire and UL 94 V-1 ?

. The other numbers you mentioned are probably UL Style numbers, referencing various wire and cable construction Recognized by UL with restrictive conditions of acceptability. I recognize those numbers as some popular internal wiring Style numbers. I hope this helps. Regards, Robert Tims

Re: Network Equipment and UL 1459/1950

Hello All, I have to agree that there shouldn't be another US (UL) standard for network equipment when the equipment can be incorporated into UL1950. UL1950 can be revised to clarify the network equipment requirements, perhaps as a deviation or an appendix (annex), or just rewording the existing

Re: UL 1581

Hello Moshe, UL1581 is the UL standard that covers test methods for many of the most common wire and cable tests performed on a variety of Listed and Recognized wire and cable types. The standard includes test methods for many tests, including: Physical Properties tests on various insulation and

Re: Signatory for US based Manufacturer

Hi all, I have a question to clarify.. Is it to be understood that the EC DofC can be signed by the US manufacturer, and authorized copy of said document just has to reside with the rep in the EC? This could save me a lot of time and bs. Regards, Bob Tims Mike Hopkins wrote: I'll

Re: EN 61000-4-4

Ray, I agree with your interpretation. Besides your good reasons, testing each port individually assures as much repeatability and uniformity of application of the transient field as possible... Regards, Bob Tims Compliance Engineer Ericsson Messaging Systems Inc. robert.t...@ericsson.com

Re: UL system for Microwave oven transformers

Robin, You do not scale the thickness as such when increasing the voltage rating. Insulation Thickness is directly related to the degree of Mechanical protection that needs to be achieved. Insulation thickness is only partially (brain stoppage for lack of a better word!) related to voltage

Re: Ground Wire Markings

Hi Doug, Sounds, most likely like the old telephone game, ie, he heard that she said that he said that this is what we had to do. I've never heard of such a thing as you stated it. Most likely, the Dell group had to replace wire that was somehow unsuitable for whatever application they were

Re: any insight appreciated

Lisa, The 10 ohms per square seems high to be critically connected with EMC directly..(maybe ESD ONLY???). I would have to say that the move to 20 ohms won't have much of an effect Now, the retest debate is interesting... If you have a TCF, I would recommend submitting your changes to

Re: CTI (Comparative Tracking Index)

Doug, You may already know the standards that cover the CTI test, but I thought I'd list them anyways: ASTM D3638, IEC 112, and UL746A Those sources will give you the test methods to help interpret any results, and also to compare IEC ratings with UL ratings. I believe that is what you

Re: Comparative Tracking Index

Rick, The Comparitive Tracking Index (CTI), ASTM D3638 and UL746A, is a test intended to show the susceptibility to surface tracking of solid electrical insulating materials when exposed under electrical stress, to a contaminant solution.This test applies to relatively low voltages under 600

RE: Notified or Competent Body?

Bob, Thanks for the clarification. I got those notified and competent bodies confused, apparently. Regards, Bob

RE: Notified or Competent Body?

Mel, What you state I agree with you in Ed's case, but there are circumstances where he may want to set up a TCF with a notified bodyOne of the cases being if his unit is too large to test normally, and would need a field evaluation... In that case he would want a notified body report to

Noise in Power Leads - Follow -Up

Hi Everyone, I have an update on that 500-900 mv spike at 50MHz that we encountered on our power lead. Attempts to alleviate the problem outside the power supply, by the use of torroids and adding ground connections did not help as much as needed, so we immediately turned our attention to the
