We just had a light niche inspection fail because the inspector read on 3ms data sheet that the compound is for fresh pools and fountains only. I have spoken to the head inspector and he stands by his field inspectors opinion that the 3m product is not suitable. SCP distributors cannot find an approved salt water potting compound and have gone up the ladder in 3m with no one that can answer the question.
I noticed in another thread that Jason Lion said the level of salt 3000 ppm in swimming pools is still considered fresh water but according to Wikipedia fresh water is considered to be less than 500 ppm. Some other sources say its 1000 ppm.
So my question is, where do i find a definition of fresh water from an authority that i could quote to the inspection department?
