This document specifies the general aspects of impact resistant unplasticized poly(vinyl chloride) (PVC-HI) solid wall piping systems intended for water supply and for buried and above-ground drainage and sewerage under pressure. In conjunction with ISO 1452-1, 1452-2 and 1452-3, it is applicable to PVC-HI pipes, fittings, valves and ancillary equipment, their joints and to joints with components of other plastics and non-plastics materials intended to be used for the following: a) water mains and services lines buried in the ground, b) conveyance of water above ground for both outside and inside buildings; c) buried and above-ground drainage, sewerage and treated waste water under pressure. It is applicable to piping systems intended for the supply of water up to and including 25 °C (cold water), intended for human consumption and for general purposes as well as for waste water under pressure. This documents are also applicable to components for the conveyance of water and waste water up to and including 45 °C. The piping system according to this International Standard is intended for the conveyance of cold water up to pressures of 2.5 MPa and especially in those applications where special performance requirements are needed, such as impact loads and pressure fluctuations, up to pressure of 2.5 MPa.
