30、ical Committee ISO/TC 138 “Plastics pipes, fittings and valves for the transport of fluids” in collaboration with Technical Committee CEN/TC 155 Introduction The System Standard, of which this is Part 2, specifies the requirements for a piping system and its components when made from polyethylene of
31、 raised temperature resistance (PE-RT). 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
32、of ISO 22391 provides no information 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 characteristics of pipes. At the date of publication of th
33、is 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
34、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 poly(vinyl chloride) (PVC-C) 4 DIN EN ISO
35、 22391-2:2010-04 EN ISO 22391-2:2009 (E) 1 Scope This part of ISO 22391 specifies the characteristics of pipe 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 installa
36、tions within buildings for the conveyance of water, whether or not the water is intended for human consumption (domestic systems) and for heating systems, under the design pressures and temperatures appropriate to the class of application according to ISO 22391-1. This part of ISO 22391 covers a ran
37、ge of service conditions (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
38、 well as of other 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 o
39、f those specified in ISO 22391-1. NOTE 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 regulations and installation practices or codes. 2 Normative references The

46、 terms For the purposes of this document, the terms, definitions, symbols and abbreviated terms given in ISO 22391-1 apply. 4 Material 4.1 Pipe material The material from which the pipe is made shall be polyethylene of raised temperature resistance (PE-RT). 4.2 Evaluation of LPLvalues The pipe mater
47、ial shall be evaluated in accordance with ISO 9080 or equivalent, with internal pressure tests being carried out in accordance with ISO 1167-1 and ISO 1167-2, in order to determine the LPLvalues. The LPLvalue thus determined shall be at least as high as the corresponding values of the reference curv
48、es given in Figure 1 or Figure 2 (taken from ISO 24033:2009) over the complete range of times. NOTE 1 One equivalent way of evaluation is to calculate the LPLvalue for each temperature (for example 20 C, 60 C and 95 C), individually.
