BS EN ISO 22391-12009 ICS 23.040.01; 91.140.60; 93.025 NO COPYING WITHOUT BSI PERMISSION EXCEPT AS PERMITTED BY COPYRIGHT LAW BRITISH STANDARD Plastics piping systems for hot and cold water installations Polyethylene of raised temperature resistance PE-RT Part 1 General ISO 22391-12009 Licensed Copy athen reading, Reading University Library, 31/01/2010 0601, Uncontrolled Copy, c BSI This British Standard was published under the authority of the Standards Policy and Strategy Committee on 31 January 2010 BSI 2010 ISBN 978 0 580 60034 0 Amendments/corrigenda issued since publication Date Comments BS EN ISO 22391-12009 National foreword This British Standard is the UK implementation of EN ISO 22391-12009. The UK participation in its preparation was entrusted to Technical Committee PRI/88/2, Plastics piping for pressure applications. The UK Committee would like to emphasize that compliance with this British Standard does not necessarily mean that products are fit for non-potable hot water pipes. The requirements contained in this standard are not necessarily indicative of all the perance requirements, or the suitability of pipework for the service conditions, likely to be encountered in a particular pipework application in the UK. In particular i The normal maximum operating cold water supply pressure in the UK is 12. bar, a pressure that some application classes of pipe in this standard do not meet. ii This standard does not specifically describe push-fit joints that are the predominant jointing in UK but defines mechanical fittings in general. iii There is a disparity between the malfunction temperature R100 C/ quoted in Table 1 of Part 1 of this standard and the malfunction temperatures applicable to boilers R110 C/ coning to BS EN 297199D, BS EN D832000 and BS EN 621996. Current UK practice can be found in BS 7291-1 which should be consulted when applying this standard. Pipe systems not coning to BS 7291-1 could be sub- jected to temperatures in service for which they have not been tested. iv The unique and traditional practice in the UK is to use products certified to BS 7291 Class S for all applications, as defined in BS 7291-1. This is recognized in the National Annex to BS EN 12828 that requires the use of systems suitable for the maximum temperatures and pressures for their intended application specified in BS 7291-1. This standard does not replace BS 7291 parts 1, 2 and 3 Class ‘S’ which contain detailed requirements for perance and contact with drinking water for pipes, fittings and joints manufactured from Poly- butylene and PEX materials.

The legisla- tion setting out the requirements for water supply installations in the UK is as follows - the Water Supply Water Quality Regulations 2000, Regulation 31 England; - the Water Supply Water Quality Regulations 2001, Regulation 31 Wales; - the Water Supply Water Quality Regulations 2001, Regulation 27 Scotland; - the Water Supply Water Quality Regulations 2007, Regulation 30 Northern Ireland for installations for public water supplies; - the Water Supply Water Fittings Regulations 1999, England and Wales; - the Water Byelaws 2000, Scotland and -the current requirements for Northern Ireland for installations for consumers premises.

Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations.

The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission IEC on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 22391-1 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 2, Plastics pipes and fittings for water supplies. This second edition cancels and replaces the first edition ISO 22391-12007, which is extended from only dealing with PE-RT material referred to as Type I to cover PE-RT materials Type I and Type II. ISO 22391 consists of the following parts1, under the general title Plastics piping systems for hot and cold water installations Polyethylene of raised temperature resistance PE-RT ⎯ Part 1 General ⎯ Part 2 Pipes ⎯ Part 3 Fittings ⎯ Part 5 Fitness for purpose of the system 1 This System Standard does not incorporate a Part 4 Ancillary equipment or a Part 6 Guidance for installation. For ancillary equipment, separate standards can apply. Guidance for installation of plastics piping systems made from different materials, intended to be used for hot and cold water installations, is covered by ENV 12108.

The piping system is intended to be used for hot and cold water installations. In respect of potential adverse effects on the quality of water intended for human consumption caused by the products covered by ISO 22391, the following are relevant. a This part of ISO 22391 provides no ination as to whether the products can be used without restriction. b Existing national regulations concerning the use and/or characteristics of the products remain in force. This part of ISO 22391 specifies the general aspects of the plastics piping system. At the date of publication of this part of ISO 22391, System Standards Series for piping systems of other plastics materials used for the same application are the following ISO 15874 all parts, Plastics piping systems for hot and cold water installations Polypropylene PP ISO 15875 all parts, Plastics piping systems for hot and cold water installations Crosslinked polyethylene PE-X ISO 15876 all parts, Plastics piping systems for hot and cold water installations Polybutylene PB ISO 15877 all parts, Plastics piping systems for hot and cold water installations Chlorinated polyvinyl chloride PVC-C Licensed Copy athen reading, Reading University Library, 31/01/2010 0601, Uncontrolled Copy, c BSI 标准分享网 w w w .b z f x w .c o m 免费下载 w w w . b z f x w . c o m BS EN ISO 22391-12009 Licensed Copy athen reading, Reading University Library, 31/01/2010 0601, Uncontrolled Copy, c BSI w w w . b z f x w . c o m BS EN ISO 22391-12009 INTERNATIONAL STANDARD ISO 22391-12009E ISO 2009 – All rights reserved 1 Plastics piping systems for hot and cold water installations Polyethylene of raised temperature resistance PE-RT Part 1 General 1 Scope This part of ISO 22391 specifies the general characteristics of piping systems made of ⎯ polyethylene of raised temperature
