ISO 15540:2016规定了测定标称直径不超过150 mm的非金属软管组件和非金属补偿器耐火性的试验程序。如果获得适当的试验台条件，则可用于较大尺寸。 它用于证明在ISO 15541规定的试验台上发生火灾后，软管组件和非金属补偿器是否仍然紧密，即使在承受验证压力的情况下也是如此。 仅允许水作为试验介质。以确保软管或非软管损坏时操作人员和试验台的最大安全- 金属补偿器在试验过程中，不允许使用可燃试验介质。

ISO 15540:2016 specifies a test procedure for determining the fire resistance of non-metallic hose assemblies and non-metallic compensators with nominal diameter of up to 150 mm. It may be used for larger sizes provided proper test bench conditions are obtained. It serves for proving whether, after the period of fire effect on the test bench specified in ISO 15541, hose assemblies and non-metallic compensators continue to be tight, even when subjected to proof pressure. Only water is permitted as a test medium. With a view to ensuring maximum safety for both the operating personnel and the test bench in the event of damage to the hose or non-metallic compensator during the test, the use of combustible test media is excluded.
