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 ISO 7511:1999

Publication date:   Mar 18, 1999

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.
