21、 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 organiza
22、tions, 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 t
23、he 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
24、 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 21138-2 was prepared by Technical Committee ISO/TC 138, Plasti

30、PP) and polyethylene (PE) Part 2: Pipes and fittings with smooth external surface, Type A 1 Scope This part of ISO 21138, together with ISO 21138-1, specifies the definitions and requirements for pipes with a smooth external surface (Type A), fittings and systems based on unplasticized poly(vinyl ch
31、loride) (PVC-U), polypropylene (PP) and polyethylene (PE) structured-wall piping in the field of non-pressure systems for underground drainage and sewerage. NOTE 1 These pipes, fittings and the system can be used for highway drainage and surface water. This part of ISO 21138 specifically refers to P
32、VC, PP and PE materials. NOTE 2 Other thermoplastic materials can be added via an addendum. This part of ISO 21138 specifies test methods and test parameters. This part of ISO 21138 covers a range of pipe and fitting sizes, materials, pipe constructions and nominal ring stiffnesses, and gives recomm
33、endations concerning colours. NOTE 3 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. In conjunction with ISO 2113
34、8-1, it is applicable to PVC-U, PP and PE structured-wall pipes and fittings, to their joints and to joints with components of other plastics and non-plastics materials intended to be used for buried piping systems for the transport of drainage and sewage. It is applicable to PVC-U, PP and PE struct
35、ured-wall pipes and fittings with or without an integral socket with elastomeric ring seal joints as well as welded and fused joints. NOTE 4 For dimensions larger than DN/OD 1200, or DN/ID 1200, this part of ISO 21138 can serve as a general guide regarding appearance, colour, physical and mechanical
36、 characteristics as well as performance requirements.
