Plastics piping systems. Glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP). Report on the determination of mean abrasion after a defined number of test cycles Ingestion-build-48348 Note: BS AU 209-la does1 Scope This Technical Report describes a method for determining the mean abrasion of the inner surface of glass reinforced thermosetting polyester resin (GRP) pipes conforming to EN 14364, measured after a defined number of test cycles of a specified water abrasive mixture. NOTE The test is performed on a semi circular channel pipe test piece.
