| Resumen: | This document specifies the definitions and requirements for solid-wall pipes with or without internal skin and smooth internal and external surfaces extruded from the same compound throughout the wall, fittings and the system of polyethylene (PE) piping systems to be intended for use in non-pressure underground drains and sewers for foul wastewater. NOTE 1: Products complying with this document can also be used in non-pressure underground drains and sewers for surface water. This document is applicable to: a) non-pressure drains and sewers, which are intended to be used buried underground outside the building structure; reflected in the marking of products by "U"; and b) non-pressure drains and sewers, which are intended to be used buried underground both outside (application area code "U") and within the building structure, reflected in the marking of products by "UD". This document specifies test methods referred to in this document and test parameters. This document is applicable to pipes and fittings with or without an integral socket. This document covers a range of pipe and fitting sizes, stiffness classes, tolerance classes and gives recommendations concerning colours. 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 any relevant national regulations and installation practices or codes. In conjunction with CEN/TS 12666-2 it is applicable to PE pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for buried piping systems for non-pressure drains an sewers. The fittings can be manufactured by injection moulding or can be fabricated from pipes and/or mouldings. This document is applicable to PE pipes and fittings for the following types of joints: Elastomeric ring seal joints; Butt fused joints; Electrofusion joints; Mechanical joints; NOTE 3: Pipes, fittings and other components conforming to any of the plastics product standards listed in the Annex D (informative) may be used with pipes and fittings conforming to this European Standard, provided they conform to the requirements for joint dimensions given in Clause 7 and to the requirements of Clause 7 and Table 13. |
