The GB/T 21477-2008 standard provides a test method for the fire resistance performance of hose assemblies in ships and marine technology. It specifies in detail the process of simulating ship fire scenarios and conducting fire resistance tests on hose assemblies, including fire source conditions, test time and evaluation points for component integrity, sealing and other performance. Reliability of hose assemblies in ship fires can be judged through this standard, providing a basis for manufacturers to control product mass, ship design and construction and select qualified components, and helping to improve the overall fire safety level of ships.
