Abstract

This Part of EN 1452 specifies the characteristics of fittings made from unplasticized poly(vinyl chloride) (PVC-U) for piping systems in the field of water supply. It also specifies the test parameters for the test methods referred to in this standard. In conjunction with Parts 1, 2, and 5 of EN 1452 and ENV 1452-7 it is applicable to PVC-U fittings and to joints with components of PVC-U, other plastics and non-plastics materials intended to be used for the following: a) water mains and services buried in ground; b) conveyance of water above ground for both outside and inside buildings; for the supply of water under pressure at approximately 20 °C (cold water) intended for human consumption and for general purposes. This standard is also applicable to fittings for the conveyance of water up to and including 45 °C. For temperatures between 25 °C and 45 °C figure A.1 in annex A of EN 1452-2:1999 applies. Depending on the jointing method, this standard is applicable to the following types of fittings: - fittings for solvent cementing; - elastomeric ring seal fittings. This standard is applicable to PVC-U flange adapters and to the corresponding flanges made from various materials. PVC-U fittings can be manufactured by injection-moulding and/or be fabricated from pipe. NOTE Fittings for mechanical joints, made from various materials are described in ENV 1452-6.
