CEN/TC 155/WG 11 - System for non-pressure drainage and sewerage - PP (solid wal)

This European Prestandard gives guidance for the assessment of conformity to be included in the manufacturer's quality plan as part of the quality system. This prestandard includes: a) requirements for materials, components, joints and assemblies given in EN 1852-1; b) requirements for the manufacturer's quality system; NOTE 1 It is recommended that the quality system conforms to EN ISO 9001:1994 or EN ISO 9002:1994, as applicable. c) definitions and procedures to be applied if third party certification is involved.

This standard covers PP materials both with normal E-moduli and with higher E-moduli, designated as HM (higher modulus), and gives a range of nominal sizes, and pipe series and gives recommendations concerning colours.

This Part of prEN 1852 specifies the requirements for pipes, fittings and the system of polypropylene (PP) piping systems in the field of non-pressure under- ground drainage and sewerage outside the building structure (application area code "U") and for non-pressure underground drainage and sewerage for both buriedin ground within the building structure (application area code "D") and outside the building structure. This is reflected in the marking of products by "U" and "UD".

This European Standard specifies the requirements for solid-wall pipes, fittings 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.
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 European Standard.
This European Standard covers a range of nominal sizes, a range of pipe series/stiffness classes and gives recommendations concerning colours.
NOTE 1   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 and Part 3 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 European Standard is applicable to PP-MD pipes with or without an integral socket.
NOTE 2   The fittings can be manufactured by injection-moulding or be fabricated from pipes and/or mouldings.
NOTE 3   Requirements and limiting values for application area code "D" are given in Table 4, Table 7 and Table 13.
NOTE 4   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 European Standard, when they conform to the requirements for joint dimensions given in Clause 6 and to the requirements of Table 13.
