- a) 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.
- b) ventilating pipework associated with a);
- c) rainwater pipework within the building structure (see Figure 1, key 16).
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.
