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.
