Corrosion resistant coatings, where applicable, are utilized to extend the life of copper alloy sprinklers beyond that which would otherwise be obtained when exposed to corrosive atmo- spheres. Although corrosion resistant coated sprinklers have passed the standard corrosion tests of the appli- cable approval agencies, the testing is not representative of all possible corrosive atmospheres. Consequently, it is recommended that the end user be consulted with respect to the suit- ability of these coatings for any given corrosive environment.
