MANY VERY VALID POINTS
U R making here and couldn't agree more!!
However, when the law will change I think that is only logical (but who is logical you're going to ask
) that crafts that were manufactured before the change will keep their staus i.e. cat B or cat C on their CE mark.
However, this is ONLY a speculation and it would worth our while, I think, that we (as a group) try to ask the questions you are making and try to get an answer from someone or the relevant authority/ies?
