This part of prEN 17176 specifies the characteristics for the fitness for purpose of oriented unplasticized poly(vinyl chloride) (PVC-O) 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 1452-3, EN ISO 1452-4 and EN 12842 this part is applicable to PVC-O pipes, PVC-O and PVC-U fittings, cast iron 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 and sewerage 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 and water for irrigation under pressure. This part of prEN 17176 is also applicable for the conveyance of water, waste water and water for irrigation up to and including 45 °C. For temperatures between 25 °C and 45 °C, prEN 17176-2:2017, Figure C.1 applies.
