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 for human consumption and raw water prior to treatment
attention is drawn to 5.3 of this European Standard. Components manufactured for water for general 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 Part 1 and Parts 3 to 5 of EN 12201, it is applicable to PE pipes, their joints and to joints with
components of PE and other materials intended to be used under the following conditions:
a) allowable operating pressure, PFA, up to 25 bar 1);
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 of EN 12201-
1:2011.
NOTE 3 Pipes constructions including barrier layers are not covered by this document.
EN 12201 covers a range of allowable operating pressures and gives requirements concerning colours and
additives.
It covers three types of pipe:
PE pipes (outside diameter dn) including any identification stripes;
PE pipes with co-extruded layers on either or both the outside and/or inside of the pipe (total outside diameter
dn) as specified in Annex B, where all layers have the same MRS rating;
PE pipes (outside diameter dn) with a peelable, contiguous thermoplastics additional layer on the outside of the
pipe (‘coated pipe’) as specified in Annex C.
NOTE 4 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.
NOTE 5 Assessment of the resistance to slow crack growth of the PE pipe compound used for the manufacture of products

In addition, black pipes may be identified by blue stripes, according to national preference. Blue pipes or black pipes with blue stripes are intended for the conveyance of water for human consumption only.
Pipes intended for other purposes, drainage and sewerage shall be black or black with brown stripes or according to national preference.
The outer coextruded layer of coextruded pipes (see Annex B) or the outer peelable layer of peelable layer pipes (see Annex C) for pipe intended for the conveyance of water for human consumption shall be either black or blue. In addition identification stripes may be used according to national preference for the application. The outer coextruded layer of coextruded pipes (see Annex B) or the outer peelable layer of peelable layer pipes (see Annex C) for pipe intended for other purposes shall be either black or black with brown stripes or brown or according to national preference. In addition identification stripes of a different colour may be used according to national preference for the application.
NOTE 1 In some countries, pipes made from non-pigmented compound in conjunction with an external peelable layer are permitted, providing the compound conforms to the requirements of this standard. If this is allowed in a country, this should be clearly stated in the national foreword. NOTE 2 For above ground installations, all components other than black should be protected from direct UV light. NOTE 3 The national preference for colour should be stated in the National Foreword.
