scope:

This part of EN 1329 specifies the recommended practice for installation of unplasticized poly(vinyl chloride) (PVC-U) piping systems in the field of soil and waste discharge (low and high temperature) inside buildings (marked with "B") and of soil and waste discharge systems for both inside buildings and buried in ground within the building structure (marked with "BD"). In conjunction with one of the parts 1 to 3, 5 and 7 of EN 1329, and with the appropriate Part(s), it is applicable to PVC-U pipes, fittings ancillary components and their joints and to joints with components (marked with "B" or "BD") 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. Pipes and fittings which are marked with "B" are intended to be used above ground only. Pipes and fittings which are marked "BD" are intended to be used above and buried in ground within the building structure. For use buried in ground within the building structure are intended only those components with nominal outside diameters equal to or greater than 75 mm (marked with "BD"). This standard is also applicable to the techniques of jointing to components made from materials other than PVC-U.
