This part of prEN 17176 specifies the general aspects of oriented unplasticized poly(vinyl chloride) (PVC-O), for solid wall piping systems intended for water supply, pressurized sewer systems and irrigation systems to be used underground or above-ground where protected to direct sunlight. In conjunction with prEN 17176-2, prEN 17176-3, EN ISO 1452-4, it is applicable to PVC-O pipes, PVC-O fittings, and valves, 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; b) conveyance of water for both outside and inside buildings; c) drainage, sewerage and treated waste water under pressure; d) Irrigation under pressure. It is applicable to piping systems intended for the supply of water under pressure 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 part of prEN 17176 is also applicable to components for the conveyance of water and waste water up to and including 45 °C. For temperatures between 25 °C and 45 °C, prEN 17176-2:2017, Figure C.1 applies. The piping system according to this European Standard is intended for the conveyance of cold water up to pressures of 25 bars2) and especially in those applications where special performance requirements are needed, such as impact loads and pressure fluctuations, up to pressure of 25 bars.
