Scope

This Standard specifies the performance and testing of metallic element and frangible glass bulb sprinklers and sprayers, as listed in Table 1.1.
NOTE: Sprinklers and sprayers will be referred to throughout this text as sprinklers.
Whilst this Standard recognizes that there are sprinklers other than those listed in Table 1.1, the acceptance of these sprinklers is dependent on their documented approval and listing by a recognized authority. Full testing procedures for sprinklers not listed in Table 1.1 are not necessarily included in this Standard.
