This document specifies the requirements for solid-wall pipes and fittings with or without internal and/or external skin, and the system of piping systems made from mineral modified polypropylene materials (PP-MD) in the field of non-pressure underground drainage and sewerage outside the building structure (application area code "U"), and non pressure underground drainage and sewerage for both buried in ground within the building structure (application area code "D") and outside the building structure. NOTE 1 The skins are made of PP compound without mineral modifier. This is reflected in the marking of products by "U" and "UD". It also specifies the test parameters for the test methods referred to in this document. This document covers a range of nominal sizes, a range of pipe series/stiffness classes and gives recommendations concerning colours. NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selection from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. In conjunction with Part 2 of EN 14758 (see Foreword) it is applicable to PP-MD pipes and fittings, their elastomeric sealing ring joints and to joints with components of other plastics and non-plastics materials intended to be used for buried piping systems for non-pressure underground drainage and sewerage. This document is applicable to PP-MD pipes with or without an integral socket. NOTE 3 The fittings can be manufactured by injection-moulding or be fabricated from pipes and/or mouldings. NOTE 4 Requirements and limiting values for application area code "D" are given in Table 4, Table 7 and Table 13. NOTE 5 Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex B can be used with pipes and fittings conforming to this document, when they conform to the requirements for joint dimensions given in Clause 6 and to the requirements of Table 13.
