Plastics piping systems for non-pressure underground drainage and sewerage - Structured-wall piping systems of unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) - General requirements and performance characteristics
This European Standard, together with EN 13476-2 and EN 13476-3, specifies the definitions and general
requirements for pipes, fittings and the system based on unplasticized poly(vinyl chloride) (PVC-U),
polypropylene (PP) and polyethylene (PE) structured-wall piping systems that are to be used for non-pressure
underground drainage and sewerage systems.
This standard is applicable to:
a) structured-wall pipes and fittings, which are to be used buried in the ground outside a building structure
only; reflected by the marking of products by “U”;
b) structured-wall pipes and fittings, which are to be used buried in ground both outside (application area
code “U”) and within a building structure (application area code “D”); reflected in the marking of products
by “UD”.
In conjunction with EN 13476-2 and EN 13476-3 it is applicable to structured-wall pipes and fittings with or
without an integral socket with elastomeric ring seal joints, as well as welded and fused joints.
This part specifies general aspects and gives guidance concerning a national selection of requirement levels
and classes where part 2 and part 3 of this standard provide options.
EN 13476-2 and EN 13476-3 specify material characteristics, dimensions and tolerances, test methods, test
parameters and requirements for pipes with smooth internal and external surfaces, Type A, and pipes with
smooth internal and profiled external surfaces, Type B.
This standard, together with EN 13476-2 and EN 13476-3, covers a range of pipe and fitting sizes, materials,
pipe constructions, stiffness classes and tolerance classes and offers recommendations concerning colours.
NOTE 1 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.
NOTE 2 Pipes, fittings and other components conforming to any plastic product standards referred to in clause 2 can
be used with pipes and fittings conforming to this standard, when they conform to the requirements for joint dimensions
given in part 2 and part 3 of this standard and to the performance requirements given in Clause 9.
NOTE 3 For dimensions larger than DN 1200 OD/ID this document may serve as general guideline regarding
appearance, colour, physical and mechanical characteristics as well as performance requirements.
