1 Scope
This document specifies the characteristics of solid-wall pipes made of oriented unplasticized
poly(vinyl chloride) (PVC-O) for piping systems intended to be used underground or
above-ground (where protected from direct sunlight), for water supply, buried drainage,
sewerage, treated wastewater and irrigation under pressure. It also specifies the
test parameters for the test methods referred to in this document.
In conjunction with ISO 16422-1 and ISO 16422-5, this document 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 wastewater under pressure;
-
d) irrigation under pressure.
This document 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 wastewater under pressure.
This document is also applicable to components for the conveyance of water and wastewater
up to and including 45 °C. For temperatures between 25 °C and 45 °C, see Figure C.1.
The piping system according to this document is intended for the conveyance of cold
water up to pressures of 25 bar1 and especially in those applications where special performance requirements are needed,
such as impact loads and pressure fluctuations, up to pressure of 25 bar.
