21、07 All rights 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
22、 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 Commissio
23、n (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 co
24、mmittees 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 no
25、t be held responsible for identifying any or all such patent rights. ISO 21138-3 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 1, Plastics pipes and fittings for soil, waste and drainage (including land drainage). ISO
26、 21138 consists of the following parts, under the general title Plastics piping systems for non-pressure underground drainage and sewerage Structured-wall piping systems of unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE): Part 1: Material specifications and perfo

30、ressure underground drainage and sewerage Structured-wall piping systems of unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) Part 3: Pipes and fittings with non-smooth external surface, Type B 1 Scope This part of ISO 21138, together with ISO 21138-1, specifies th
31、e definitions and requirements for pipes with a non-smooth external surface (Type B), fittings and systems based on unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) structured-wall piping systems in the field of non-pressure systems for underground drainage and se
32、werage. 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 PVC, PP and PE materials. NOTE 2 Other thermoplastic materials may be added via an addendum. This part of ISO 21138 specifies test methods and test pa
33、rameters. This part of ISO 21138 covers a range of pipe and fitting sizes, materials, pipe constructions and nominal ring stiffnesses, and gives recommendations concerning colours. NOTE 3 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, ta
34、king into account their particular requirements and any relevant national regulations and installation practices or codes. In conjunction with ISO 21138-1, this part of ISO 21138 is applicable to PVC-U, PP and PE structured-wall pipes and fittings, to their joints and to joints with components of ot
35、her 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 structured-wall pipes and fittings with or without an integral socket with elastomeric ring seal joints as well as welded and fused joi
36、nts. NOTE 4 Pipes, fittings and other components conforming to any plastics product standards referred to in Clause 2 can be used with pipes and fittings conforming to this part of ISO 21138, when they conform to the requirements for joint dimensions given in parts 2 and 3 of this International Stan
37、dard and to the performance requirements given in Clause 10. NOTE 5 For dimensions larger than DN/OD 1200 or DN/ID 1200 this standard can serve as a general guide regarding appearance, colour, physical and mechanical characteristics as well as performance requirements. Test methods are not included
