Plastics piping systems for pressure and non-pressure drainage and sewerage. Glass-reinforced thermosetting plastics (GRP) systems based on unsaturated polyester (UP) resin Ingestion-build-95349 The standard has been revised1 Scope This document specifies the properties of piping system components made from glass reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP). It is suited for all types of drainage and sewerage with or without pressure. This document is applicable to GRP UP piping systems, with flexible or rigid joints with or without end thrust load bearing capability, primarily intended for use in direct buried installations.
