European foreword
This document (prEN 12201-1:2021) has been prepared by Technical Committee CEN/TC 155 “Plastics
piping systems and ducting systems”, the secretariat of which is held by NEN.
This document will supersede EN 12201-1:2011.
In comparison with the previous edition, the following technical modifications have been made:
— The revision of this System Standard has been carried out to add the PE 100-RC type materials with
enhanced resistance to slow crack growth. Annex A discusses the performance of this type of
material and gives additional information for non-conventional installation techniques. The size
range has been increased to 3000 mm diameter, test methods have been updated, and new test
methods have been added for PE 100-RC materials.
System Standards are based on the results of the work being undertaken in ISO/TC 138 “Plastics pipes,
fittings and valves for the transport of fluids”, which is a Technical Committee of the International
Organization for Standardization (ISO).
They are supported by separate standards on test methods to which references are made throughout the
system Standard.
The System Standards are consistent with general standards on functional requirements and on
recommended practice for installation.
EN 12201 consists of the following Parts:
— EN 12201-1, Plastics piping systems for water supply, and for drainage and sewerage under pressure
— Polyethylene (PE) — Part 1: General (this document);

prEN12201-1:2020 (E)
Introduction
The System Standard, of which this is Part 1, specifies the requirements for a piping system and its
components when made from polyethylene (PE). The piping system is intended to be used for water
supply intended for human consumption, including the conveyance of raw water prior to treatment,
drainage and sewerage under pressure, vacuum sewer systems, and water for other purposes.
In respect of potential adverse effects on the quality of water intended for human consumption, caused
by the products covered by the EN 12201 series:
a) this document provides no information as to whether the products may be used without restriction
in any of the Member States of the EU or EFTA;
b) products intended for use in water supply systems should comply, when existing, with national
regulations and testing arrangements that ensure fitness for contact with drinking water.
Requirements and test methods for components of the piping system are specified in
prEN 12201-2:2021, prEN 12201-3:2021 and prEN 12201-4:2021.
Characteristics for fitness for purpose are covered in prEN 12201-5:2021 [1]. CEN/TS 12201-7 [2] gives
guidance on the assessment of conformity.
This Part of EN 12201 covers the general aspects of the plastics piping system.
prEN12201-1:2021 (E)
1 Scope
This document 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 6 of this document. Components manufactured for water for
other purposes, drainage and sewerage are possibly not suitable for water supply for human consumption.
It also specifies the test parameters for the test methods referred to in this document.
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:
1)
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 series covers a range of allowable operating pressures and gives requirements 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 guidance or regulations and
installation practices or codes.
