Hi Nick, My mistake. Sometimes I'm just itching to get up on that stump :-)
I'll just call it a "third party compliance certificate." I still don't see the true value of judging a third party compliance certificate strictly by age. Either the certificate references the correct applicable standards...or it doesn't. On the same token...either the certificate applies to the product as currently being built...or it doesn't. Lastly, either the agency or lab issuing the certificate stands behind it...or they don't. In the strictest sense, all of these properties of the third compliance certificate are independent of its age. If the certificate is judged solely by its age; then the "judge" is simply taking a calculated risk that a certificate of a certain age is good.

The OP asked about "compliance certificates". I took that to mean a third party test certificate, not the manufacturers EC declaration of Conformity. None of what I was talking about in my post was with reference to the DofC. Nick.
