This document specifies the requirements for solid wall pipes
with smooth internal and external surfaces, extruded from the same
formulation throughout the wall, fittings and the system of
unplasticized poly(vinyl chloride) (PVC-U) piping systems intended
for soil and waste discharge applications (low and high
temperature):
-
inside buildings (application area code “B”);
-
for both inside buildings and buried in ground within the
building structure (application area code “BD”).

rainwater pipework within the building structure.
This document also specifies the test parameters for the test
methods that are referred to.
This document covers a range of nominal sizes, a range of pipes
and fittings series and gives recommendations concerning
colours.
NOTE 6
It is the responsibility of the purchaser or specifier to make
the appropriate selections from these aspects, taking into
