GB/T 21476-2008

This standard specifies the design, construction, and performance requirements for test benches used to evaluate the fire resistance of hose assemblies intended for shipboard and offshore applications. It is applied in marine engineering and shipbuilding contexts to ensure that hydraulic, pneumatic, and fluid transfer hoses can maintain integrity and functionality when exposed to fire conditions. The standard provides a uniform testing framework for manufacturers, classification societies, and regulatory bodies to certify hose assemblies for use in critical ship systems, such as fuel, lubrication, and hydraulic lines.
