Plastics piping systems for water supply and for buried and above-ground drainage and sewerage under pressure. Unplasticized poly(vinyl chloride) (PVC U) - Valves Ingestion-build-115288 ISO/TR 21946 describes some of1 Scope This part of ISO 1452 specifies the characteristics of valves made from unplasticized poly(vinyl chloride) (PVC U) for piping systems intended for water supply and for buried and above ground drainage and sewerage under pressure. It also specifies the test parameters for the test methods referred to in this part of ISO 1452. In conjunction with ISO 1452 1, ISO 1452 2, ISO 1452 3 and ISO 1452 5 it is applicable to PVC U valves with components
