1 Scope

This document specifies the test methods 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 conditions, this document is also applicable to the determination of the fire resistance of non-metallic hose assemblies and non-metallic compensators with larger nominal diameters. performance. This test is used to prove that after a flame is applied for a period of time on the test bench specified in GB/T 21476-2024, the When the non-metallic hose assembly and non-metallic compensator can continue to remain leak-free. The test medium is only water. To ensure that the operator can For the safety of the test bench, flammable test media are not allowed to be used.
