NOTE 2 Part 7 of the EN 12201 series has been prepared as a CEN/TS to allow further development CEN/TS 12201-7 is not mandatory under the Public Procurement Directives (2004/18/EC and 2004/17/EC).

As yet there is no pan-European agreement on water quality requirements, so existing UK regulations remain in force for public drinking water suppliers

The following regulations apply to the approval of substances and products used in the provision of public water supplies within the United Kingdom:

a) England – Regulation 31 of The Water Supply (Water Quality) Regulations 2000 (Statutory Instruments 2000 No 3184) b) Wales – Regulation 31 of The Water Supply (Water Quality) Regulations 2001 (Welsh Statutory Instrument 2001 No 3911 (W.323) c) Scotland – Regulation 27 of The Water Supply (Water Quality) (Scotland) Regulations 2001

d) Northern Ireland – Regulation 30 of The Water Supply (Water Quality) (Amendment) Regulations (Northern Ireland) 2009 (Statutory Rules of Northern Ireland 2009 No.246)

For further information, go to: http://www.legislation.gov.uk/browse

As part of the regulations, all pipes and fittings used to convey drinking water supplies are required to be approved under the provisions of Regulation 31, as applicable In addition, manufacturers may obtain approval under the Water Regulations Advisory Scheme (WRAS) to confirm that use of their products will not cause adverse effect on water quality or a risk to health of consumers

National Annex NA provides additional information on the selection and installation of piping systems and components in the UK

Attention is drawn to the following statutory regulation: Health & Safety

Introduction

The System Standard, of which this is Part 2, 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 product covered by EN 12201 (all parts):

a) this standard provides no information as to whether the product 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 must comply, when existing, with national regulations and testing arrangements that ensure fitness for contact with drinking water

NOTE On April 2006, EC Commission set up a revised mandate (M/136) asking CEN to propose harmonised product standards and support standards for test methods which could be used for assessing the fitness for contact with drinking water

In parallel, EC Commission has launched processes for a regulation of construction products (CPR) to be substituted to CP directive (89/106/EEC) and for the revision of drinking water directive (98/83/EC) If relevant, when the outputs of these processes will be known, European Product Standards will be amended by the addition of an Annex Z under Mandate M136, which will contain formal references to the applicable requirements Until such amendments, the current national regulations remain applicable

Requirements and test methods for material and components, other than pipes, are specified in

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

EN 12201-2:2011+A1:2013 (E)

 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 2 500 mm Test methods have been updated as

appropriate and in accordance with other parts of this standard

Introduction

The System Standard, of which this is Part 2, 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 product covered by EN 12201 (all parts):

a) this standard provides no information as to whether the product 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 must comply, when existing, with national regulations and testing arrangements that ensure fitness for contact with drinking water

NOTE On April 2006, EC Commission set up a revised mandate (M/136) asking CEN to propose harmonised product standards and support standards for test methods which could be used for assessing the fitness for contact with drinking water

In parallel, EC Commission has launched processes for a regulation of construction products (CPR) to be substituted to CP directive (89/106/EEC) and for the revision of drinking water directive (98/83/EC) If relevant, when the outputs of these processes will be known, European Product Standards will be amended by the addition of an Annex Z under Mandate M136, which will contain formal references to the applicable requirements Until such amendments, the current national regulations remain applicable

Requirements and test methods for material and components, other than pipes, are specified in

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

EN 12201-2:2011+A1:2013 (E)

 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 2 500 mm Test methods have been updated as

appropriate and in accordance with other parts of this standard

According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following

countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech

Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece,

Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,

Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom
