Glass-reinforced thermosetting plastics (GRP) pipes - Determination of initial ring stiffness
|Publication Date:||22 November 2018|
|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, and within the specified deflection limits, each is equally valid and may be used for any diameter.
