本文件规定了埋地和地上玻璃纤维增强热固性塑料（GRP）管道系统的水泥或包裹接头的试验方法。本文件仅适用于接头，包括证明其设计的试验方法。它假设接头可能会或不会受到静水压端推力的影响。 9.2、9.4至9.6（含9.4至9.6）中详述的试验适用于拟用于埋地或地上应用的胶结或包裹接头。9.3中详述的弯曲试验可用于证明接头拟用于埋地应用或拟用于上述特定用途的设计- 可能认为测试合适的地面情况。 除9.3中详述的程序外，这些试验程序适用于所有标称尺寸的管道和管件的接头。9.3中详述的试验适用于DN 600及以下管道和配件的接头。本试验适用于评估在参考标准中规定的温度下输送液体应用的接头。 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。本试验程序仅适用于型式试验目的。 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 cemented or wrapped 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 cemented or wrapped 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 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 applied for type testing purposes only. This document is applicable only to the joint and specifies methods of test to prove its design.
