The work of preparing International Standards
13、 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 p
14、art 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
15、 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 t

20、ents and the performance requirements for multilayer pipes based on thermoplastics intended to be used for water supply outside buildings, for buried water mains and services and for water supplies above ground. It gives guidance for the design of piping systems consisting of multilayer pipes based
21、on thermoplastics or, for which at least 60 % of the wall thickness is polymeric material, and the inner layer in contact with water is made of polymeric material. The polymeric layers used for the stress-bearing layers are selected from polybutylene (PB), polyethylene (PE), crosslinked polyethylene
22、 (PE-X), polypropylene (PP), chlorinated poly(vinyl chloride) (PVC-C) and unplasticized poly(vinyl chloride) (PVC-U). NOTE 1 For the purpose of this document, crosslinked polyethylene (PE-X) as well as adhesives are to be considered as thermoplastic materials, and polyethylene of raised temperature
23、resistance (PE-RT) is to be considered as polyethylene (PE). This document is applicable to piping systems used for the conveyance under pressure of cold water (up to approximately 20 C) for drinking. It is also applicable to piping systems for the conveyance of water (up to and including 40 C) for
24、general purposes. It applies where special functional requirements are needed. NOTE 2 As an example, the different pipe layers can provide information on colour, barrier and mechanical properties, according to the intended application. 2 Normative references The following referenced documents are in
