BSI PD CEN/TR 13801:2014

This Technical Report gives the recommended practice for installation of thermoplastics 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”).

This Technical Report provides material dependent installation techniques but it is important that the general installation practice as given in the relevant parts of EN 12056 for B application are taken into account in manufacturer’s instructions, subject to any applicable national and/or local regulations.

This Technical Report is applicable to thermoplastics pipes and fittings as specified in the associated standards EN 1329-1 [1] (PVC-U), EN 1451-1 [2] (PP), EN 1453-1 [3] (PVC-U with structured-wall pipes), EN 1455-1 [4] (ABS), EN 1519-1 [5] (PE), EN 1565-1 [6] (SAN+PVC) and EN 1566-1 [7] (PVC-C), their joints and to joints with components of other plastics and non-plastics materials intended to be used for the following purposes:

1. soil and waste discharge pipework for the conveyance of domestic waste waters (low and high temperature);

   NOTE 1 See Clause 4 for waste discharge temperature limits.

2. ventilating pipework associated with a);

3. rainwater pipework within the building structure (see Figure 1, key 16).

It is applicable to pipes and fittings, marked with “B”, which are intended to be used above ground only, and to pipes and fittings, marked “BD”, which are intended to be used above and buried in ground within the building structure.

NOTE 2 Only those components as specified in the relevant associated standard with nominal outside diameters equal to or greater than 75 mm (marked with “BD”) are intended for use buried in ground within the building structure. The term “within building structure” covers all gravity discharge pipework within a building, including the elements installed below the slab and buried in the ground.

If specified in the relevant associated standard, this Technical Report also covers soil and waste discharge pipework fixed externally onto the building (see Figure 1, key 17). It is not applicable to pipework that passes under the building without any connection from the discharge system.

NOTE 3 According to the associated standards, for external above ground soil and waste discharge, additional requirements depending on the climate, will be agreed between the manufacturer and the user.

According to the associated standards, components conforming to other standards on plastic piping systems may be used with pipes and fittings conforming to a given associated standard, if they conform to the requirements for joint dimensions and functional requirements of the given associated standard.
