标准摘要
[中文适用范围]： 本国际标准规定了用于确定船舶工程系统中使用的包含弹性或弹性体密封件的金属阀门、管道接头和类似管道部件的耐火性的测试程序。 本国际标准的目的是确定在满足 ISO 19922 要求的测试台上进行防火测试一段时间后，管道部件是否保持紧密，并且没有任何可能影响其功能的故障，即使在承受耐压时也是如此。 [外文原描述]： 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.
