Organization: CEN
Publication Date: 1 April 2019
Status: active
Page Count: 26
ICS Code (Plastics fittings): 23.040.45
scope:

This document specifies the characteristics of solid-wall oriented unplasticized poly(vinyl chloride) (PVC-O) fittings for piping systems intended for water supply and for buried drainage, sewerage, treated waste water and irrigation under pressure or above-ground where protected from direct sunlight. The scope of this document is limited to double sockets, repair couplings, reducers and to non-end load bearing elbows.

NOTE 1 The scope of this document is restricted to fittings on the market during the preparation of this document. Therefore tees, flange adaptors, etc., are excluded from this version of the standard.

NOTE 2 For double sockets, repair couplings, and reducers there are no special fittings designs for end-load bearing applications. However, restrained gaskets can be used for end-load bearing applications. In that case, the requirements of EN 17176-5 are applicable.

It also specifies the test parameters for the test methods referred to in this document.

In conjunction with EN 17176-1 and EN 17176-5, this document is applicable to oriented PVC-O fittings 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.

This document is applicable to piping systems intended for the supply of water with a maximum allowable operating pressure (PFA) up to and including 25 bar1). The piping system according to this European Standard is intended for the conveyance of cold water up to and including 45 °C and especially in those applications where special performance requirements are needed, such as impact loads and pressure fluctuations. For temperatures between 25 °C and 45 °C, EN 17176-2:2019, Figure C.1 applies.

This document specifies a range of fittings sizes and pressure classes and gives a requirement and recommendations concerning colours.

NOTE 3 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

1) 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.
