GB/T 21477-2024 Ships and marine technology—Fire resistance of non-metallic hose assemblies and non-metallic compensators—Test methods
Abstract
This document specifies the test method for determining the fire resistance of non-metallic hose assemblies and non-metallic compensators with a nominal diameter not exceeding 150 mm. When the test bench meets the requirements, this document is also applicable to determining the fire resistance of non-metallic hose assemblies and non-metallic compensators with a larger nominal diameter.
This test is used to demonstrate that, after applying flames on the test bench specified in GB/T 21476-2024 for a certain period of time, the non-metallic hose assemblies and non-metallic compensators can continue to maintain no leakage when subjected to test pressure.
The test medium is only allowed to be water. To ensure the safety of operators and the test bench in the event of damage to the non-metallic hose assemblies or non-metallic compensators during the test, the use of flammable test media is not permitted.
