1 Scope
This European Standard specifies the requirements for pipes, fittings and the piping
system of chlorinated poly(vinyl chloride) (PVC-C) solid-wall piping systems in the
field of soil and waste discharge (low and high temperature) inside buildings (marked
with “B”) and for soil and waste discharge systems for both inside buildings and buried
in ground within the building structure (marked with “BD”).
NOTE 1: The application area “inside buildings”, according to this standard, applies to the
interior area of the building only. The application area “within the building structure”
conforms to the requirements for “inside buildings” according to prEN 12056‑1.
It also specifies the test parameters for the test methods referred to in this standard.
This standard is applicable to PVC-C pipes and fittings, their joints and to joints
with components of other plastics and non-plastics materials intended to be used for
the following purposes:
-
a) soil and waste discharge pipework for the conveyance of domestic waste waters (low
and high temperature);
-
b) ventilation pipework associated with a);
-
c) rainwater pipework within the building structure.
It applies to pipes and fittings marked with “B”, which are intended to be used inside
buildings and outside buildings fixed onto the wall.
It applies to pipes and fittings, marked with “BD”, which are intended to be used
for both inside buildings and buried in ground within the building structure.
NOTE 2: Only components marked with “BD” are generally to be used buried in ground within
the building structure; these are required to have a nominal ring stiffness of at
least SN 4 and a nominal outside diameter equal to or greater than 75 mm.
NOTE 3: Pipes and fittings of the pipe series S 25 are intended to be used for application area “B” only.
This standard is applicable to PVC-C pipes and fittings of the following types:
-
— plain-ended;
-
— with integral elastomeric ring seal socket;
-
— with integral solvent cement socket;
-
— with integral dual purpose socket for elastomeric ring seal joints and/or solvent
cement joints;
whereby the fittings can be manufactured by injection-moulding or be fabricated from
pipes and/or mouldings.
NOTE 4: Components conforming to any of the Product Standards listed in the bibliography can
be used with pipes and fittings conforming to this standard, provided they conform
to the requirements for joint dimensions and to the functional requirements given
in this standard.
This standard covers a range of nominal sizes, a range of pipe series and gives recommendations
concerning colours.
NOTE 5: 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 codes.
