1.1 Scope. 1.1.1* This standard gives the performance and requirements for new fire hose couplings and adapters with nominal sizes from 3/4 in. (19 mm) through 8 in. (200 mm) and the specifications for the screw thread connections on those couplings and adapters. A.1.1.1 Some fire-fighting organizations use small hose less than 3/4 in. (19 mm) nominal diameter fitted with garden hose couplings. Such couplings should have 0.75-11.5 NH (garden hose thread) threads conforming to ANSI/ASME B1.20.7, Standard on Hose Coupling Screw Threads. 1.1.2 This standard also gives the performance and requirements for the mating surfaces of non-threaded fire hose couplings and adapters with nominal sizes of 4 in. (100 mm) and 5 in. (125 mm). Fee required
