Plastics piping systems for pressure and non-pressure water supply, drainage or sewerage — Glass reinforced thermosetting plastics (GRP) systems based on unsaturated polyester (UP) resin


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
water supply, drainage and sewerage with or without pressure. Types of water supply include, but are
not limited to, raw water, irrigation, cooling water, potable water, salt water, sea water, penstocks in
power plants, processing plants and other water-based applications. 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
