Rene, You are probably doing the "let's get this plastic enclosure to pass EMC". But, first let's look at any potential safety hazards. The potential for hazard is mainly electrical - the coating begins to flake and thereby defeating the insulation barrier.
Now, in terms of regulatory requirements, this is definitely a ULism. UL has an approval process to test that both the materials and the process employed are suitable to prevent flaking under a range of environmental conditions. The materials and the process are then recognized by UL. In my experience, we had the coated covers shipped to us with the Condition of Compliance in each box or lot. This worked out fine. The only glitch I remember was once when UL did not recognize a baby company of the actual recognized company.
