RE: Awards for Worst EMC/PS qualities

I once had a Safety Engineer tell me that a class 2 transformer had opened during the overload test. He was measuring resistance primary to secondary (Duh!!!). This guy is still in the Safety Field but they don't work here thank God!!! Monty Griffith Senior Product Safety Engineer EMC Quality

Entry-less Chassis

Group: I have a designer who is seeking any information, IEEE standards, EMA... about entry-less chassis. This device allows the user to swap hard drives and other components without intrusion. This would be similar to hot swap devices but not the same. Does anyone have a clue about any

NFPA 701

Group: I have a client who is trying to build a product that complies with NFPA 701, however all the materials seem to have a UL94 rating of some kind. Does anyone know of an official cross reference between UL94 ratings and NFPA 701? Thanks!!! Monty Griffith

RE: EU / USA regulatory law

Tony: Very good response !!! The only thing that I would like to add is that older standards like UL478 were in large based on NFPA70 (The National Electrical Code). Now days the trend seems to be that Agencies like UL are trying a marketing approach called one stop certification, where by

RE: Re[2]: Demos and Eval Units Now Require CE Mark???

It has always been my understanding that the CE mark could be put on the equipment by a distributor in the EU as long as the distributor has the TIF. If this is truly the case then a product does not have to be CE marked to enter the country or how else would it get to the distributor.

RE: EN60950 - Internal wiring colours

Hey guys I have an antique version of IEC 364 (Similar to NEC but for Europe) which indicates Identification of Conductors by colour as indicated in IEC446 which now has been replaced by IEC 60446 IDENTIFICATION OF CONDUCTORS BY COLOURS OR NUMERALS and there is also DIN 40705 IDENTIFICATION OF

RE: NRTL Value

You should always have the inspector call the engineer who did the initial evaluation before he leaves so that you understand the exact position of both. Generally there is justification for the acceptance of the product that is not stated in your FUS. The engineer can help you resolve most of

RE: CE mark self certification

To be proper the NCB should only issue test reports, the Declaration always has to come from the manufacturer but can be based on your own testing or an NCB. NCB's can still very good in that they can give you access to markets in other countries besides just the European Union. Just a thought!!!

RE:Ground Bond Test

As usual Egon, you are correct we have abandoned are old 25 Amp tester and created a new fixture to allow us to do the continuity tests at twice the rating of the branch protection, 30,40 or 60 Amps. We tried many different approaches and quoted many different standards but this issue is one that

RE: CSA -US mark acceptance

CSA is fully accredited by OSHA as an NRTL and their mark is just as acceptable as UL, ETL, WYLE or any of the U.S. based NRTL's. The fundamental requirements for Listing described in the National Electrical Code NFPA 70, do not specify UL only. Article 90-7 Examination of Equipment for Safety

RE: EN50082-1:1997 EN55024

I agree that you should test and progressively increase the levels, because the lower level tests pre-condition the samples and if you fail then you have already obtained the data to apply the highest passing level. This is even more important when you are doing more destructive tests like TOV.

RE: Rodents, part II

I don't know if it has been said, but we have copperheads around where we live and of course we don't want them in our yard and we generally be-head the ones we find. All snakes have a very strong sense of smell which is part from their nostrils but even more from their disgusting forked tongue

EN60945

Does anyone know what the vibration requirements for this standard are? (Sine,half Sine, triangle, frequency and amplitude, how many G's the equipment must withstand) I also saw where it was equal to MIL-STD-1399, is that true? Any help would be appreciated. Thanks!!! Monty Griffith Test

RE: OEM Issues (EU context)

The person who places the device on the market is ultimately responsible for compliance with all directives. So you would be responsible to assure your modifications do not affect the original compliance attributes. Thanks!!! Monty Griffith Test Engineer INTERGRAPH FEDERAL SYSTEMS Tel: (256)
