Glass-reinforced thermosetting plastics (GRP) pipes — Determination of initial ring stiffness

General information

Current stage: 20.00 Effective date: 15 maj 2024

Originator: ISO

Owner: ISO/TC 138/SC 6

Type: International Standard

Scope

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.
