And this one IS not to get away with, due to the reasons I gave: 1. Lack of specification of AC adapters transfer attenuation 2. The high risk that adapters are to be replaced once in lifetime
Even the same type of adapter a few years later might be completely different as the transfer attenuation is an unspecified parameter. Regards, Ing.

I'm sure you apply your extended test program ethically, but there are many instances where such ethical statements are taken as a justification for abuse of the testing process or divergence between the interpretations adopted by regulatory bodies, as I indicated. >Hey what the heck, there is more in >EMC testing then just following >standards and legal requirements !! Test houses that seek to maximize their profits would, of course, agree with you. There is, however, a large body of opinion that considers that there is no more to EMC testing than 'as little as you can get away with'. As always, a balance is necessary. -- OOO - Own Opinions Only. Try www.jmwa.demon.co.uk and www.isce.org.uk Things can always get better. But that's not the only option.
