This Standard specifies methods for determining the initial specific ring stiffness of glass-reinforced thermosetting plastics (GRP) pipes and glass-reinforced thermosetting plastics mortar pipes. Three methods are given, and within the specified deflection limits each is equally valid and may be used for any diameter.
