適用范圍：This International Standard specifies methods of test for flexible socket-and-spigot joints with elastomeric sealing elements for glass-reinforced thermosetting plastics (GRP) piping systems intended for buried and above-ground pipelines. It covers methods of test for the leaktightness of the joint only, when subjected to specified combinations of longitudinal extension (draw), angular movement (angular deflection), vertical compression (misalignment) and internal pressure. This International Standard is applicable to joints for either pressure or non-pressure applications. NOTE The joints tested in accordance with this International Standard are subjected to conditions which measure their ability to function and thereby prove the design of the joint, especially for type-testing 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 liquids are conveyed at temperatures specified in the referring specifications (see clause 2).
