Plastics piping systems for non-pressure drainage and sewerage. Polyester resin concrete (PRC) - Pipes and fittings with flexible joints Ingestion-build-132972 operating requirements1 Scope This European Standard applies to pipes and fittings made from polyester resin concrete (PRC, see 3. 1. 23), intended to be used within a drain or sewer system operating without pressure. It applies to products for use in buried installations to be installed by open trench techniques or pipe jacking. It applies to pipes, fittings and their joints of nominal sizes from DN 150 to DN 3000 for circular cross sections, from WN HN 300 450 to WN HN
