Re: AW: Declaration of Conformity

Lothar, Of all the DofC's I've witnessed in my travels that have been generated from test labs, very few have required the manufacturer's signature. In fact, they were signed by an officer of the test lab. However, to be fair, these DofC's issued from test labs may be only intended for

Re: UL vs. EN..

Hi George, A main difference is Annex ZB (normative) found in EN60950. There are some clause 6 deviations in there. Also, although Annexes NA and ZC are informative, you might want to be aware of them, too. None of these annexes are found in UL1950. I hope this helps. Best

EMC Books
