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
This Technical Report describes a method for determining the mean abrasion of the inner surface of glassreinforced
thermosetting polyester resin (GRP) pipes conforming to EN 14364, measured after a defined
number of test cycles of a specified water/abrasive mixture.
