标准摘要
[中文适用范围]： 本国际标准规定了两种测试方法，指定为方法A和方法B，用于检查玻璃增强热固性塑料（GRP）管道和配件在短期内压下的密封性。 方法A是适用于单轴应力下管道的水压试验。 方法B是适用于管件的气动测试。 注：接头密封性或管道耐长期静水压力的测试方法由其他标准涵盖。 [外文原描述]： This International Standard specifies two test methods, designated method A and method B, for checking the leaktightness of glass-reinforced thermosetting plastics (GRP) pipes and fittings under short-term internal pressure. Method A is a hydraulic test applicable to a pipe under uniaxial stress. Method B is a pneumatic test applicable to fittings. NOTE Test methods for the leaktightness of joints or for the resistance of the pipe to long-term hydrostatic pressure are covered by other standards.
