标准范围

本文件规定了用于埋地和地上玻璃增强热固性塑料（GRP）管道应用的带弹性密封元件的柔性非抗推力承插接头的试验方法。它仅涵盖了当受到纵向延伸（拉伸）、角运动（角偏转）、垂直于管道轴线的压缩（变形）和内部压力的指定组合时，接头的密封性和抗损坏性的测试方法。本文件适用于压力或非压力应用的接头。笔记？根据本文件测试的接头要经受测量其功能能力的条件，从而证明接头的设计，特别是用于型式测试目的。这些测试程序适用于所有公称尺寸的管道和配件的接头。这些测试适用于评估在参考标准中规定的温度下输送液体的应用中的接头。本文件中的测试程序会损坏测试件，测试后不适合重复使用。本试验程序旨在用于型式试验。

This document specifies test methods for flexible non-thrust resistant socket-and-spigot joints with elastomeric sealing elements for buried and aboveground glass-reinforced thermosetting plastics (GRP) pipeline applications. It covers methods of test for the leaktightness and resistance to damage of the joint only, when subject to specified combinations of longitudinal extension (draw), angular movement (angular deflection), compression (deformation) perpendicular to the pipe axis and internal pressure. This document is applicable to joints for either pressure or non-pressure applications.

NOTE       The joints tested in accordance with this document are subjected to conditions which measure their ability to function and thereby prove the design of the joint, especially for type test purposes.

These test procedures are applicable to joints for pipes and fittings of all nominal sizes. The tests are suitable for the evaluation of joints intended for applications in which the liquids are conveyed at temperatures specified in the referring standards.

The test procedures in this document are damaging to the test piece which will not be suitable for reuse after these tests. The test procedure is intended for type testing purposes.
