scope:

Specifies test methods for flexible and reduced-articulation socket-and-spigot joints with elastomeric sealing elements for above ground and buried glass-reinforced thermosetting plastics (GRP) pipeline applications. It covers methods of test for the leaktightness and resistance to damage of the joint only, when subject to specified combinations of longitudinal extensions (draw), angular movement (angular deflection), vertical compression (misallignment) and internal pressure. This standard is applicable to joints for either pressure or non-pressure applications.
