Part 5: Fitness for purpose of the system.
This part of EN 17176 specifies the characteristics of the fitness for purpose of oriented unpiasticized poly(vinyl chloride) (PVC-O) solid wall 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 It also specifies the test parameters for the test methods referred to in this document.
NOTE 1 This document is not intended for on-site resting of pipe systems.
In conjunction with EN 17176-1. EN 17176-2, CEN/TS 17176-3 and EN ISO 1452-3. it is applicable to PVC-O pipes, PVC-O fittings, 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.
Joints constructed of other materials shall meet their own standards in addition to the fitness of purpose requirements specified in this document.
It 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 document 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.
NOTE 2 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.
