Glass-reinforced thermosetting plastics (GRP) pipes — Determination of initial ring stiffness
|Publication Date:||1 July 2019|
|ICS Code (Plastics pipes):||23.040.20|
This document specifies methods for determining the initial ring stiffness of glass-reinforced thermosetting plastics (GRP) pipes. Two methods are given (constant load and constant deflection), and within the specified deflection limits, each is equally valid and can be used for any diameter.
