The corrosion resistant coatings have passed the standard corrosion test required by the approving agencies indicated in the Approval Chart(s).
These tests cannot and do not represent all possible corrosive environments. Prior to installation, verify through the end-user that the coatings are
compatible with or suitable for the proposed environment. For automatic sprinklers, the coatings indicated are applied to the exposed exterior sur-
faces only. Note that the spring is exposed on sprinklers with Polyester, ENT coatings. For ENT coated automatic sprinklers, the waterway is coated.
