用于压力和非压力排水和污水的塑料管道系统 - 基于不饱和聚酯（UP）树脂的玻璃增强热固性塑料（GRP）系统 - 证明螺栓法兰接头设计的测试方法

[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）管道系统的螺栓法兰接头的测试方法。 本文件仅适用于接头并涵盖证明其设计的测试方法。 它假设接头会或不会受到静压端推力的影响。 9.2、9.4 至 9.6 中详述的测试适用于用于埋地或地上应用的螺栓法兰接头。9.3 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，其中测试可能被认为是合适的。 除了 9.3 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。9.3 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 bolted flange joints for buried and above-ground glass-reinforced thermosetting plastics (GRP) piping systems. This document is only applicable to the joint and covers methods of test to prove its design. It assumes that the joint either is or is not intended to be subject to the effects of hydrostatic end thrust. The tests detailed in 9.2, 9.4 to 9.6 inclusive are applicable to bolted flange joints intended to be used in buried or above-ground applications. The bending tests detailed in 9.3 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 may be considered appropriate. With the exception of the procedure detailed in 9.3, these test procedures are applicable to joints for pipes and fittings of all nominal sizes. The tests detailed in 9.3 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 test to prove its design.
