I think the answer is that the FCC allows declared compliant devices to be sold in another unit WITHOUT testing. This has allowed PCs on the market with as much as 30dB over Class B limits.
Why did the FCC put in place a compliance methodology that guarantees non-compliant products are released? The answer IMHO is simple. Volume. Sheer volume of PC manufacturers and PC related products. Manufacturers of assembled PCs didn't bother with the test anyway so the FCC tried to make some sense out of it. The time had come for the regulatory bodies to face facts. Even with the high number of non-compliant products, "stuff" seems to be working OK. I would suggest that the regulatory bodies either relieve the emissions spec limit by 20db ( thereby allowing diligent manufacturers to save money) and/or rewite the standards to reflect the process our safety brethern use. That is: component level compliance. Charles Grasso ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
