Plastics piping systems for non-pressure underground drainage and sewerage - Polypropylene (PP) - Part 1: Specifications for pipes, fittings and the system

This part of EN 1852 specifies the requirements for solid wall pipes with smooth internal and external surfaces extruded from the same compound/formulation throughout the wall, fittings and the system of polypropylene (PP) piping systems intended for use for:
-   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".
This standard covers PP materials without mineral modifiers.
It also specifies the test parameters for the test methods referred to in this standard.
NOTE 1 Solid wall multilayer pipes with different formulation throughout the wall and foamed core pipes are covered by EN 13476-2 [1] (see also CEN ISO/TR 27165 [2]).
This standard covers a range of nominal sizes, and pipe series 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 CEN/TS 1852-2, it is applicable to PP 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 underground drainage and sewerage.
The fittings can be manufactured by injection-moulding or be fabricated from pipes and/or mouldings.
NOTE 3   Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex C can be connected to pipes and fittings conforming to this standard, when they conform to the requirements for joint dimensions given in Clause 6 and to the requirements of Table 14.

surfaces extruded from the same compound/formulation throughout the wall, fittings and the system of

polypropylene (PP) piping systems intended for use for:

— 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”.
This standard covers PP materials without mineral modifiers.

It also specifies the test parameters for the test methods referred to in this standard.

NOTE 1 Solid wall multilayer pipes with different formulation throughout the wall and foamed core pipes are

covered by EN 13476-2 [1] (see also CEN ISO/TR 27165 [2]).

This standard covers a range of nominal sizes, and pipe series 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 CEN/TS 1852-2, it is applicable to PP 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 underground drainage and sewerage.

The fittings can be manufactured by injection-moulding or be fabricated from pipes and/or mouldings.

NOTE 3 Pipes, fittings and other components conforming to any of the plastics product standards listed in

Annex C can be connected to pipes and fittings conforming to this standard, when they conform to the

requirements for joint dimensions given in Clause 6 and to the requirements of Table 14.
