Plastics piping systems for water supply, and for drainage and sewerage under pressure - Polyethylene (PE) - Part 1: General

Scope

This European Standard specifies the general aspects of polyethylene (PE) pressure piping systems (mains and service pipes) for buried or above ground applications, intended for the conveyance of water for human consumption, raw water prior to treatment, drainage and sewerage under pressure, vacuum sewer systems, and water for other purposes.
NOTE 1 For PE components intended for the conveyance of water intended for human consumption and raw water prior to treatment attention is drawn to Clause 5 of this European Standard. Components manufactured for water for other purposes, drainage and sewerage may not be suitable for water supply for human consumption.
It also specifies the test parameters for the test methods referred to in this standard.
In conjunction with Parts 2 to 5 of EN 12201, it is applicable to PE pipes, fittings, valves, their joints and to joints with components of other materials intended to be used under the following conditions:
a) allowable operating pressure, PFA, up to 25 bar );
b) an operating temperature of 20 °C as a reference temperature;
c) buried in the ground;
d) sea outfalls;
e) laid in water;
f) above ground, including pipes suspended below bridges.
NOTE 2 For applications operating at constant temperatures greater than 20 °C and up to 40 °C, see Annex A.
EN 12201 (all parts) covers a range of allowable operating pressures and gives requirements concerning colours and additives.
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 guidance or regulations and installation practices or codes.
