标准摘要
[中文适用范围]： 本国际标准规定了一种全尺寸试验（FST）方法，用于确定在指定温度和内部压力下热塑性塑料管道中产生的裂纹的停止或扩展。 该方法还适用于确定临界压力、临界应力和临界温度参数。 它适用于评估用于供应气体或液体的热塑性塑料管道的性能。 在后一种情况下，管道中也可能存在空气。 [外文原描述]： ISO 13478:2007 specifies a full-scale test (FST) method for determining the arrest or propagation of a crack initiated in a thermoplastics pipe at a specified temperature and internal pressure. The method is also suitable for the determination of defined critical pressure, critical stress and critical temperature parameters. It is applicable to the assessment of the performance of thermoplastics pipes intended for the supply of gases or liquids. In the latter case, air could also be present in the pipe.
