I agree with Ted that you are correct, Jim. The IP code is widely 
misunderstood as being the same as a pass/fail requirement in one of 
the product safety standards. In fact it is not, it is standardised 
method of making measurements of the performance of a product with 
regard to ingress protection, and whether or not a product is 
acceptable for any given application is not the purpose of the code. 
It is wrong to think of the results of testing to EN 60529 in terms 
of 'pass' or 'fail'. It is there to assign a code number to a given 
enclosure and whether this is adequate for the intended application 
is (in most cases) the subject of other standards.

Nick.
