Jeff, Mr. Eszlari asked, Is it true that European safety agency approval for critical components may not be required for CE? Answer, No, it is NOT required (compulsory) for a manufacturer to use European safety agency approval for critical components. Having a certificate from an accredited

Yeah, I second that. I try to believe in as little confirmation as possible. Extended stacks of paper don't verify anything. For the EMC stuff I think that you really want to deal with labs that have NIST approval through NVLAP or A2LA. Among other things if you don't need an FCC ID you can ship

CENELEC Decisions on EN 60950

For a screened room to function as a screened room, no earth is required. It's the metal conduit of the shielding material that will be reference potential (if you insist : ground) for all measurements. All external cables (mains) should be filtered to this reference potential, preferably to the

I absolutely disagree about having a separate ground for the shielded room. Any ac fault inside the room can potentially cause a personnel hazard, as will any lightning strike to the vicinity. A separate ground for the shielded room is acceptable ONLY if it is bonded to building ground. The risk

Kate, My apologies for the apparent slight. In the US, where I'm located, NVLAP and A2LA were simply familiar to me. I happen to us NVLAP when I qualified a former employers site. Quite possibly their are more certifying bodies in the US than just those two and if they carry NIST credentials I

Hi Ed, Yes, I agree. The way you suggested is an ideal method to get Ambient noise in the Conducted emission test. Please allow me to make two more points about impedance vs. frequency: (1) It is inconvenient in practice to find a resistive load sized to draw the same amount of power. We

Mike, sorry you disagree. Inside the room, all equipment is referenced to the room itself, there is no new safety risk introduced by the room being grounded differently. Outside the room, again, all equipment is referenced tightly to the room, so the operator does not see any differential.
