Plastics piping systems. Glass-reinforced plastics (GRP) components. Determination of the amounts of constituents Ingestion-build-47553 Limitation of voltage and/or energy1 Scope This document specifies a method for the determination of constituent materials of a test sample cut from a glass reinforced plastics (GRP) component intended for use in a piping system. It includes determination of resin, glass, aggregate and filler contents. It is also applicable to the determination of the type and arrangement of the reinforcements. If used to determine the amounts of constituent materials in layered constructions it may be
