Plastics piping systems — Glass-reinforced thermosetting plastics (GRP) pipes and fittings — Test methods to prove the leaktightness of the wall under short-term internal pressure

Systèmes de canalisations en plastiques — Tubes et raccords en plastiques thermodurcissables renforcés de verre (PRV) — Méthode d'essai pour établir l'étanchéité de la paroi sous une pression interne à court terme

Abstract / scope

This International Standard specifies two test methods, designated method A and method B, for checking the leaktightness of glass-reinforced thermosetting plastics (GRP) pipes and fittings under short-term internal pressure.

Method A is a hydraulic test applicable to a pipe under uniaxial stress.

Method B is a pneumatic test applicable to fittings.

NOTE Test methods for the leaktightness of joints or for the resistance of the pipe to long-term hydrostatic pressure are covered by other standards.
