This document, together with ISO 21138-1, specifies the definitions and requirements for pipes with a non-smooth external surface and a smooth internal surface (Type B), fittings and systems based on unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) structured-wall piping systems intended to be used in non-pressure underground drainage and sewerage applications.<\/p>\n
NOTE 1 Pipes, fittings and the systems complying with this document can also be used for highway drainage and surface water.<\/p>\n
This document specifies test methods and test parameters.<\/p>\n
This document covers a range of pipe and fitting sizes, materials, pipe constructions and nominal ring stiffnesses, and gives recommendations concerning colours.<\/p>\n
NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and installation practices or codes.<\/p>\n
In conjunction with ISO 21138-1, this document is applicable to structured-wall pipes and fittings, to their joints and to joints with components of other plastics and non-plastics materials.<\/p>\n
It is applicable to pipes and fittings with or without an integral socket with elastomeric ring seal joints as well as welded and fused joints.<\/p>\n
NOTE 3 Pipes, fittings and other components conforming to any plastics product standards referred to in Clause 2 are deemed to be suitable for use with pipes and fittings conforming to this document, when they conform to the requirements for joint dimensions given in ISO 21138-2 or ISO 21138-3 (this document) and to the performance requirements given in Clause 10.<\/p>\n
NOTE 4 For dimensions larger than DN\/OD 1200 or DN\/ID 1200, this document can serve as general guidance regarding appearance, colour, physical and mechanical characteristics as well as performance requirements.<\/p>\n
Test methods are not included in this document.<\/p>\n","protected":false},"excerpt":{"rendered":"
