Hi, I'm new to the CE marking process, so hopefully someone can point me to the right direction. The current issue is, we got a new CE marked product (A) from another company and now trying to merge such product to our which is also CE marked (B). What is it that you need to verify prior to signing such Article 12 document? Correct me if I'm wrong, the purpose of Article 12 is to state that device A is compatible with device B. So testing was done and product A does work with product B. In addition to such tests, do we have to verify that product A has all their Design and V/V docs and procedures in place? Hope that wasn't too confusing.
