玻璃纤维增强热固性塑料管道和管配件. 检验设计带弹性体密封件的锁紧套筒连接件, 包括双插孔连接件的试验方法

[中文适用范围]： 本文件规定了埋地和地上玻璃增强热固性塑料 (GRP) 管道系统的带有锁定承插口和插口的接头（包括双承口接头）和弹性密封件的测试方法。 它仅涵盖当受到指定的角运动、垂直于管轴的压缩（变形）和内部压力的组合时，接头的密封性和抗损坏性的测试方法。 它假设接头将受到静压端推力的影响。 9.2、9.3、9.4 和 9.6 中详述的测试适用于带有锁定插座和插口的接头，包括双插座接头，以及用于埋地或地上应用的弹性密封件。9.5 中详述的弯曲测试可用于证明接头设计用于埋地应用或用于特定的地上情况，在这些情况下，测试可以被认为是适当的。 除了 9.5 中详述的程序外，这些测试程序适用于所有公称尺寸的管道和配件的接头。9.5 中详述的测试适用于 DN 600 以下的管道和配件的接头。 这些测试适用于评估用于在参考标准中规定的温度下输送液体的应用的接头。 本文件中的测试程序会对测试件造成损坏，测试后测试件将不适合重复使用。 该测试程序旨在用于型式测试目的。 本文件仅适用于接头并规定了证明其设计的测试方法。 [外文原描述]： 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 testing 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. The tests detailed in 9.2, 9.3, 9.4 and 9.6 are applicable to joints with a locked socket and spigot, including double-socket joints, and with elastomeric seals intended to be used in buried or above-ground applications. The bending tests detailed in 9.5 can be used to prove the design where joints are either intended to be used in buried applications or are intended to be used in particular above-ground situations, where the tests can be considered appropriate. With the exception of the procedure detailed in 9.5, these test procedures are applicable to joints for pipes and fittings of all nominal sizes. The tests detailed in 9.5 are applicable to joints for pipes and fittings up to and including DN 600. The tests are applicable for evaluating joints intended for applications conveying liquids 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. This document is applicable only to the joint and specifies methods of testing to prove its design.
