This part of EN 1329 specifies the requirements for solid wall unplasticised poly(vinyl chloride) (PVC-U) 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 ground within the building structure (application area code "BD").
NOTE 1 The intended use is reflected in the marking of products by "B" or "BD".
NOTE 2 For use buried in ground within the building structure are intended only those components (marked with "BD") with nominal outside diameters equal to or greater than 75 mm.
This part of EN 1329 is also applicable to PVC-U pipes, 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 method referred to in this standard.
This standard covers a range of nominal sizes, a range of pipes and fittings series and gives recommendations concerning colours.
NOTE 3 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.
For external above ground application additional requirements depending on the climate should be agreed between the manufacturer and the user.
NOTE 4 Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex B can be used with pipes and fittings conforming to this European Standard, provided they conform to the requirements for joint dimensions given in Clause 6 and to the requirements of Table 15.
NOTE 5 Joints and adhesives are considered to be part of the system as covered in the scope.
