标准摘要
[中文适用范围]： 本文件规定了一种确定玻璃纤维增强热固性塑料（GRP）管长期耐压性能的方法，该方法基于试样在指定内部压力和温度下经过规定时间老化后的残余失效强度。内部环境在相关标准中予以规定，外部环境可以是空气或水。 [外文原描述]： This document specifies a method for determining the long-term pressure endurance of glass-reinforced thermosetting plastics (GRP) pipes, based on the residual failure strength of test pieces after ageing for a specified time at specified internal pressure and temperature. The internal environment is specified in the referring standard. The external environment can be air or water.
