The sprinkler temperature rating is stamped on the deflector.

Based on NFPA-13. Other limits may apply, depending on fire loading, sprinkler location, and other requirements of the Authority Having Jurisdiction.
Refer to specific installation standards.

For automatic sprinklers, the coatings indicated are applied to the exposed exterior surfaces only. Note that the spring is exposed on sprinklers with
Polyester.
4
The corrosion-resistant coatings have passed the standard corrosion test required by the approving agencies indicated in the Approval Chart. These
tests cannot and do not represent all possible corrosive environments. Prior to installation, verify through the end-user that the coatings are compat-
ible with or suitable for the proposed environment. For ENT sprinklers, all exposed surfaces and the waterway are coated, but note that the spring
is exposed.
