Plastics piping systems for drainage and sewerage. Glass-reinforced thermosetting plastics (GRP) based on polyester resin (UP). Manholes and inspection chambers Ingestion-build-50790 secondary and suburban lines1 Scope This European Standard applies to a) manholes, when made from glass reinforced thermosetting plastics (GRP) based on polyester resin (UP); b) inspection chambers, when made from glass reinforced thermosetting plastics (GRP) based on polyester resin (UP) which are intended to be used with inverts which are at a depth not exceeding 2 m. These products are intended to be used within a drain or sewer system operating without pressure or
