scope:

This part of prEN 17176 specifies the characteristics of solid-wall pipes made from oriented unplasticized poly(vinyl chloride) (PVC-O) for piping systems intended for water supply and for buried and above-ground drainage, sewerage, treated waste water and irrigation under pressure.

It also specifies the test parameters for the test methods referred to this part of prEN 17176.

In conjunction with prEN 17176-1 and prEN 17176-5, it is applicable to oriented PVC-O pipes with or without integral socket 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 and water for irrigation under pressure.

This part of prEN 17176 specifies pipes 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, EN ISO 1452-2:2009, Figure C.1 applies.

This part of prEN 17176 specifies a range of pipe sizes and pressure classes and gives requirements concerning colours.

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.

NOTE 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.

2) 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm².
