Plastics piping systems for non-pressure drainage and sewerage. Polyester resin concrete (PRC) - Manholes and inspection chambers Ingestion-build-207047 20 Category L2 automatic fire1 Scope This European Standard specifies units made from polyester resin concrete (PRC, see 3. 1. 18), and their joints, for the construction of inspection chambers with inverts not exceeding 2 m deep and for manholes, intended to be used within a drain or sewer system operating without pressure. It applies to products for use outside buildings in buried installations to be installed by open trench techniques. This document applies to nominal sizes
