Organization for Standardization is a worldwide federation of national standards bodies ISO member bodies. 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 22391-3 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 22391-32007, 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 w w w . b z f x w . c o m BS EN ISO 22391-32009 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 22391-32009 INTERNATIONAL STANDARD ISO 22391-32009E ISO 2009 – All rights reserved 1 Plastics piping systems for hot and cold water installations Polyethylene of raised temperature resistance PE-RT Part 3 Fittings 1 Scope This part of ISO 22391 specifies the characteristics of fittings for piping systems made of ⎯ polyethylene of raised temperature resistance PE-RT, Type I, and ⎯ polyethylene of raised temperature resistance PE-RT, Type II, intended to be used for hot and cold water installations within buildings for the conveyance of water, whether or not the water is intended for human consumption domestic systems and for heating systems, under t
