    20、ghts reservedForeword ISO (the International 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

    21、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) o

    22、n 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

    23、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

    24、 responsible for identifying any or all such patent rights. ISO 22391-2 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 fir

    25、st edition (ISO 22391-2:2007), 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.

For ancillary equipment, separate standards can apply.

    27、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.

This part of ISO 22391 covers a range of service co

    36、nditions (classes of application), design pressures and pipe dimension classes, and also specifies test parameters and test methods. In conjunction with the other parts of ISO 22391, it is applicable to PE-RT pipes, fittings, their joints, and to joints having components of PE-RT, as well as of othe

    37、r plastics and non-plastics materials, respectively, used for hot and cold water installations. It is applicable to pipes with or without a barrier layer or layers. It is not applicable to values of design temperature, maximum design temperature or malfunction temperature in excess of those specifie

NOTE 1 One equivalent way of evaluation is to calculate the LPLvalue for each temperature (for example

    48、20 C, 60 C and 95 C), individually. NOTE 2 The reference curves for PE-RT Type I in Figure 1 in the temperature range of 10 C to 95 C are derived from Equations (1) and (2).
