Describes the characteristics for the fitness for purpose of unplasticized poly(vinyl chloride) (PVC-U) piping systems intended for water supply and for buried and above-ground drainage and sewerage under pressure.

This part of ISO1452 specifies the characteristics for the fitness for purpose of unplasticized poly(vinyl chloride) (PVC-U) 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 ISO1452. In conjunction with ISO1452-1, ISO1452-2, ISO1452-3 and ISO1452-4, it is applicable to joints and assemblies with components of PVC-U, other plastics and non-plastics materials intended to be used for the following: water mains and services buried in ground; conveyance of water above ground for both outside and inside buildings; buried and above-ground drainage and sewerage 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 ISO1452 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, FigureA.1 of ISO1452-2:2009 applies. NOTE The producer and the end-user can come to agreement on the possibilities of use for temperatures above 45°C on a case-by-case basis.
