塑料管道系统.玻璃纤维增强塑料(GRP)元件.成分测定

[中文适用范围]： 本文件规定了从用于管道系统的玻璃增强塑料 (GRP) 部件切下的测试样品的构成材料的测定方法。 它包括树脂、玻璃、骨料和填料含量的测定。 它也适用于钢筋类型和布置的确定。 如果用于确定层状结构中的组成材料的量，则可能需要通过切割或劈开并单独测试每个层来分离层压层。 [外文原描述]： ISO 7510:2017 specifies a method for the determination of constituent materials of a test sample cut from a glass-reinforced plastics (GRP) component intended for use in a piping system. It includes determination of resin, glass, aggregate and filler contents. It is also applicable to the determination of the type and arrangement of the reinforcements. If used to determine the amounts of constituent materials in layered constructions it may be necessary to separate the laminate layers by cutting or splitting and testing each separately.
