标准摘要
[中文适用范围]: 本文件规定了测定玻璃纤维增强热固性塑料(GRP)管初始环刚度的方法。提供了两种方法(恒载法和恒挠度法),在规定的挠度范围内,两种方法均有效,且适用于任何直径。 [外文原描述]: This document specifies methods for determining the initial ring stiffness of glass-reinforced thermosetting plastics (GRP) pipes. Two methods are given (constant load and constant deflection), and within the specified deflection limits, each is equally valid and can be used for any diameter.
