标准范围

本文件规定了埋地和地上玻璃纤维增强热固性塑料（GRP）管道系统中带有锁定承插接头（包括双承插接头）和弹性密封件的接头的试验方法。本标准涵盖了仅在承受角运动、垂直于管道轴线的压缩（变形）和内部压力的特定组合时，接头密封性和抗损坏性的试验方法。它假设接头将受到静水压端推力的影响。本文件适用于压力或非压力应用的接头。这些试验适用于在参考标准中规定的温度下输送液体的应用中的接头评估。根据本文件进行试验的接头所处的条件可测量其功能能力，从而证明接头的设计，尤其是用于型式试验目的。接头仅根据本文件中详述的测试顺序和配置进行鉴定。除弯曲试验（见9.5）外，试验程序适用于所有标称尺寸的管道和管件接头。如果制造商和客户之间未另行约定，9.5中详述的弯曲试验适用于DN 600及以下管道和配件的接头。本文件中的试验程序会损坏试件，这些试件不适合在这些试验后重复使用。试验程序旨在用于型式试验目的。本文件仅适用于接头，并规定了证明其设计的试验方法。

This document specifies methods of test for joints with a locked socket and spigot, including double-socket joints, and with elastomeric seals, for buried and above ground glass-reinforced thermosetting plastics (GRP) piping systems. It covers methods of test for leaktightness and resistance to damage of the joint only, when subjected to specified combinations of angular movement, compression (deformation) perpendicular to the pipe axis and internal pressure. It assumes that the joint will be exposed to the effects of hydrostatic end thrust.This document is applicable to joints for either pressure or non-pressure applications. 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 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. The joint is only qualified according to the test sequences and configurations detailed in this document.With the exception of the bending test (see 9.5), the test procedures are applicable to joints for pipes and fittings of all nominal sizes. If not otherwise agreed between the manufacturer and the customer, the bending test detailed in 9.5 is applicable to joints with pipes and fittings up to and including DN 600.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 to be applied for type testing purposes.This document is applicable only to the joint and specifies methods of test to prove its design.
