Description / Abstract: This document specifies a method for determining by extrapolation the long-term ultimate ring bending strain and for the calculation of the long-term ultimate relative ring deflection of glass-reinforced thermosetting plastics (GRP) pipes, under wet conditions. Two methods of loading are given, one using plates the other using beam bars.
