Thanks for the responses. However, this also brings me to a follow-up question. EN55022 in clause 4.2 states that for Class A ITE a warning shall be included in the instructions for use: "Warning. This is a class A product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures". How binding is that requirement?

But since they were commercial products, and were not marketed to the "public", marketing stayed with the Class A compliance claims to avoid any confusion for the customs, which meant a sizable margin to the A limit!. Was it more expensive to make those margins to the limits? Just a bit, a lot more care in the layout took care of it. Generally two more layers did it, along with a few layout tricks. And being expensive commercial products with lots of $$ margin to start with, no real concern. And with those margins to the limit, go ahead and make some changes, they probably won't affect the DOC. ________________________________ From: Brian Oconnell <oconne...@tamuracorp.com<mailto:oconne...@tamuracorp.com>> To: EMC-PSTC@LISTSERV.IEEE.ORG<mailto:EMC-PSTC@LISTSERV.IEEE.ORG> Sent: Wednesday, February 13, 2013 5:35 PM Subject: RE: Class A or Class B on Declaration of Conformity The problem with emissions limits is their use to determine scope and applicability of other non-related directives and standards. Which is basis for some EMC reports that only indicate the equipment meets Class A limit, but the data demonstrates Class B performance. "Dinosaur-like DNA found in chicken and turkey meals" ? Probably why all unknown/exotic meats taste like chicken.

It could hardly be a requirement on the DoC because that would have to be specified in the Directive. Not all standards have 'Class A' and 'Class B', and those that do don't all define them in the same way. -- SHOCK HORROR!
