NFPA 1963 STANDARD FOR FIRE HOSE CONNECTIONS NFPA 1963 消防水带接扣性能要求
1.1* Scope. This standard gives the performance 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 mating surfaces. A.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. Work with the latest industry guidelines for standardized couplings and adapters for fire hose connections in the 2009 NFPA 1963. NFPA 1963 Standard for Fire Hose Connections provides performance 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 mating surfaces. Requirements apply to · Coupling assemblies and adapters · Screw thread connections · Non-threaded connections · Gaskets and gasket seats Keep pace with these changes in the 2009 edition of NFPA 1963 · New requirement for marking the country of origin on the surface of the product · Non-threaded caps are allowed to have pressure gaskets installed for pressure-only applications. Together with NFPA? documents that address the fire hose, couplings and connections, and nozzles, NFPA 1963 contributes to a set of standards that are designed to provide consistent requirements for the whole fire hose system.
