I don't understand how looking at the age of a Declaration of Conformity will tell you anything.
The only reason that a DOC should change is because of a change in the applicable standards. A DOC that's two weeks old could be garbage if the applicable standards hsve changed within those two weeks. On the other hand, a 10 year old DOC may be perfectly fine if there haven't been standard changes during that time. This is just another one of those rules that panders to "ease of inspection" while being meaningless. Anybody who looks for the age of a DOC is pretty much admitting that they have no idea of what the applicable standards are.

Chris You've dropped into a big debate which is going on in the higher echelons of the EU's enterprise directorate. At present, I don't think any of the new approach directives place an upper limit on the life of a conformity certificate, but there is pressure to include this in some of the Directives (e.g. Machinery) when they are revised, and also to make the certificate issuing bodies responsible for telling their customers when the standards and regulations which affect their products change. The Notified Body groups are (by and large) resisting this change. In my experience, for consumer durables most UK high street retailers want to see a certificate which is no more than 2 years old. Some of the bigger test houses put a 5 year life on their certificates, but this is not done with any authority from the Directives, although I think this is likely to be the upper limit if/when this is introduced in the directives in due course. Of course, this assumes that the product which was originally certified is the one you are still selling. If you make changes to the product, you and your certification body have to agree between you whether or not the original certificate is still valid. That's a whole new can of worms!
