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;  EN 12201-2:, Plastics piping systems for water supply, and for drainage and sewerage under pressure — Polyethylene (PE) — Part 2: Pipes (this standard);  EN 12201-3:, Plastics piping systems for water supply, and for drainage and sewerage under pressure — Polyethylene (PE) — Part 3: Fittings;  EN 12201-4 , Plastics piping systems for water supply, and for drainage and sewerage under pressure — Polyethylene (PE) — Part 4: Valves for water supply systems;  EN 12201-5, Plastics piping systems for water supply, and for drainage and sewerage under pressure — Polyethylene (PE) — Part 5: Fitness for purpose of the system;  CEN/TS 12201-7, Plastics piping systems for water supply — Polyethylene (PE) — Part 7: Guidance for the assessment of conformity.
In this revision, the scope of this standard includes two additional types of pipe;-  PE pipes with co-extruded layers on either or both the outside and/or inside of the pipe as specified in Annex B, where all layers have the same MRS rating;  PE pipes with a peelable, contiguous thermoplastics additional layer on the outside of the pipe (‘coated pipe’) as specified in Annex C. In this revision, pipe diameters specified have been increased to 2500 mm. Test methods have been updated as appropriate and in accordance with other parts of this standard.
EN 12201-1:2011, EN 12201-3:2011 [1] and prEN 12201-4:2011 [2]. Characteristics for fitness of purpose are covered in EN 12201-5:2011 and CEN/TS 12201-7 [3] gives guidance for the assessment of conformity. This Part of EN 12201 covers the characteristics of pipes. SIST EN 12201-2:2011

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 to this document is required in accordance with Table 2 of EN 12201-1:2011.

The ends of the pipe shall be cut cleanly and square to the axis of the pipe. 5.2 Colour Pipes intended for the conveyance of water for human consumption shall be black or blue. 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.
