标准摘要
[中文适用范围]： 本文件规定了一种通过外推法测定玻璃纤维增强热固性塑料（GRP）管道在湿条件下的长期极限环向弯曲应变，并计算长期极限相对环向挠度的方法。给出了两种加载方法：一种使用平板，另一种使用梁杆。 [外文原描述]： This document specifies a method for determining by extrapolation the long-term ultimate ring bending strain and for the calculation of the long-term ultimate relative ring deflection of glass-reinforced thermosetting plastics (GRP) pipes, under wet conditions. Two methods of loading are given, one using plates the other using beam bars.
