Rich, You are correct they will accept a recognize marking system without test - but it doesn't matter, if they are preparing a CB report for Europe they are required to test the label.

I don't have a copy of UL 969, so I don't know if it addresses both issues. If you are dealing with UL, I'm sure you can get them to accept UL 969 without the 60950-1 durability test. However, if you are dealing strictly with 60950-1 (as in a CB report), then the label must pass the durability test. In my experience, there is not much difference between the required hexane and turpentine/paint thinner. If I recall correctly, turpentine/paint thinner is more severe than hexane. The test itself is not very repeatable, especially if the result is marginal. Best regards, Rich On 3/26/2013 12:31 PM, Gelfand, David wrote: > Brian, > > I am not an organic chemist either.
