Painting and ATEX certification

Painting and ATEX certification

Painting and ATEX certification

The supplier of an electrical items has the item ATEX certified, we need the product to be painted to our project specific painting scheme, the european supplier claims that if the painting is done (Which is not their standard) the ATEX certification is no longer valid, is this contention correct?

RE: Painting and ATEX certification

Since it is the equipment supplier who has to do the risk analysis and issue the ATEX certification, then all matters relating the equipment specification is down to him.
I must admit, I would be surprised if painting was a critical part of the specification, but I suppose it could be.  It could just be he doesn't want to bastardise his standard equipment to suit a one off sale, which I can sympathise with.

Remember ATEX certification is still developing and interpretations vary in different European countries.  Additionally the directives are not proscriptive in that they do not contain specific lists of detailed instructions (e.g. minimum size of bolts, use this size of O-ring etc).

RE: Painting and ATEX certification

Painting is critical as the surface cannot allow a build up of static electricity and any labels or markings attached must be remain in place during service.
