本国际标准规定了两种试验方法，即方法A和方法B，用于在短期内压下检查玻璃纤维增强热固性塑料（GRP）管道和配件的密封性。 方法A是适用于承受单轴应力的管道的水压试验。 方法B是适用于配件的气动试验。 注:其他标准涵盖了接头密封性或管道耐长期静水压力的试验方法。

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.
