This European Standard specifies the requirements for solid-wall polypropylene (PP) pipes, fittings and the system intended for:

soil and waste discharge applications (low and high temperature) inside buildings (application area code "B");

soil and waste discharge applications (low and high temperature) for both inside buildings and buried in the ground within the building structure (application area code "BD").

NOTE 1The intended use is reflected in the marking of products by "B" or "BD.

NOTE 2For use buried in the ground within the building structure are intended only those components marked with "BD".

This European Standard is also applicable to PP pipes and fittings and the system intended for the following purposes:

ventilating part of the pipework in association with discharge applications;

rainwater pipework within the building structure.

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

This European Standard covers a range of nominal sizes, a range of pipes and fittings series and gives recommendations concerning colours.

NOTE 3It 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, e.g. CEN/TR 13801[1].

with integral elastomeric ring seal socket;

for butt fusion joints.

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