标准范围

ISO 19921:2005规定了测定船舶工程系统中使用的金属阀门、管接头和含有弹性或弹性密封件的类似管道部件耐火性的试验程序。ISO 19921:2005的目的是确定在满足ISO 19922要求的试验台上进行火灾试验后，管道部件是否保持紧密，且无任何可能影响其功能的故障，即使在承受验证压力的情况下。

ISO 19921:2005 specifies test procedures for determining the fire resistance of metallic valves, pipe couplings, and similar pipe components which contain a resilient or elastomeric seal and which are used in ship engineering systems.The purpose of ISO 19921:2005 is to determine whether, after the period of fire testing on a test bench which fulfils the requirements of ISO 19922, pipeline components remain tight, and without any failure which could affect their function, even when subjected to proof pressure.
