标准摘要
[中文适用范围]： 本文件规定了测定公称尺寸 DN 100 及以上玻璃增强热固性塑料 (GRP) 管道和配件在偏转条件下耐化学性能的方法。 结合 ISO 10928，本文件提供了一种评估化学环境在指定时间段后对管道或配件内部影响的方法。 测试条件和要求在参考国际标准中规定。 ISO 23856 引用了本文档。 注：已经发现，由偏转引起的应变会加速化学环境的影响；因此，这种类型的效应通常被称为应变腐蚀。 [外文原描述]： This document specifies a method for determining the chemical resistance properties of glass-reinforced thermosetting plastics (GRP) pipes and fittings in a deflected condition for nominal sizes DN 100 and larger. In conjunction with ISO 10928, this document provides a method for evaluating the effect of a chemical environment on the interior of a pipe or fitting after a specified period of time. Test conditions and requirements are specified in the referring International Standard. ISO 23856 references this document. NOTE It has been found that the effect of chemical environments can be accelerated by strain induced from deflection; hence, this type of effect is frequently referred to as strain corrosion.
