For me ATEX is always very stringent. Maybe I am wrong. I have only dealt with EEx i, EEx d, and EEx n. > The EMC directive can be self certified to standards without the use of a > notified/competent/approved body for equipment that doesn't include a rad= io > transmitter.

He actually doesn't even have to test the equipment. I do not know. I was always asked to keep the test documents. I was even told to take nice photos so that the reports are presentable. Anyway, the customers can always request for the test documents. And I will be very cautious to deal with a small vendor who does self-certification without a proper test document. > Some directives exclude other directives.

I know that the marine industry have their own EMC limits and I think you can not do self-certification.
