1 Scope
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:
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).
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.

SIST-TP CEN/TR 13801:2014
CEN/TR 13801:2014 (E)
temperature discharge occur. For the design of systems for other discharges than domestic waste, see
Clause 12 and manufacturer's recommendations.
Apply the requirements for the calculation of the flow capacity of plumbing installations, as specified in
relevant European Standards, subject to any applicable national and/or local regulations.
Design of the systems should take into account applicable national regulations with regard to reaction to fire
and fire resistance.
Design of the systems should take into account applicable national regulations on acoustic of the building,
including provision on mounting and fixing, acoustic properties of the products and noise protection.
NOTE Among European Standards, EN 12056-2 and EN 12056-3 are primarily applicable for flow capacity
calculation.
5 Storage, transport and handling
5.1 General
Attention is drawn to any relevant local and/or national safety regulations.
Avoid damage to the surfaces and ends of pipe and fittings.
Loading and handling of components made of PP-homopolymers (marked PP-H) for which performance
impact testing is carried out at 23 °C (see EN 1451-1) is not recommended at ambient temperatures lower
than +5 °C. For components made of other materials (e.g. PVC, PP-copolymers), follow the manufacturer's
instructions regarding installation at low temperature.
Support pipes with sockets and with pre-assembled fittings, in such a way that they are protected from
damage and that the ends are free from loading, e.g. by alternating the socket and non-socket ends in given
or adjacent layers.
5.2 Transport
Load pipes and fittings in such a way that no damage occurs during transport (see Figure 9).
Stack the pipes at a maximum stacking height of 1,5 m unless otherwise specified in the manufacturer’s
instructions, for example when transporting caged bundles.

Figure 9 — Loading for transport
5.3 Storage
Do not carelessly unload pipes and fittings (see Figure 10).
Provide a storage area free from substances harmful to the relevant thermoplastics (see Clause 12),
comprising smooth and level ground or a flat timber base to avoid the risk of bent or damaged pipes. Where
PE pipes are supplied in coils, store them either stacked flat one on top of the other, or (chiefly for sizes
greater than DN 90) vertically in purpose-built racks or cradles.
Avoid storage in direct sunlight over a period longer than one year. Where long-term storage and/or strong
sunlight is expected, screening from the direct rays of the sun is recommended, except for black-coloured PE
components.
Recommended maximum stacking height is 1,5 m [see Figure 10, detail a)] unless otherwise stated in the
manufacturer's instructions, for example when stacking caged bundles [see Figure 10, detail b)].

6.1 General recommendations for installation
6.1.1 Cutting of pipe
Cut pipe square to length with a fine tooth saw, or special purpose equipment (see Figure 12). Remove all
burrs at the inside and outside edges of the cut surfaces.
Prior to fusion jointing, if necessary, e.g. if the pipe ends were slightly tapered during their production cut
10 mm to 15 mm from the factory-made pipes.

Figure 12 — Cutting of pipe
To obtain a square guide line, a piece of paper may be wrapped around the pipe and the edges brought
together (see Figure 13).

6.1.2 Chamfering of pipe
6.1.2.1 Do not chamfer components made of PE or PP which are designed for butt-fusion jointing (see
6.4.3.2.2).
6.1.2.2 For components to be jointed by other techniques, the pipes may be chamfered if necessary
according to the manufacturer's instructions. Chamfer the pipes with a medium file or special purpose
equipment. Provide approximately matching chamfers on the pipe and the socket; with an angle α between
15° and 45°. Keep a remaining wall thickness of at least e/3 (see Figure 14).

6.1.3 Fabricating
Do not fabricate on site thermoplastics components by any other means (fusion, socket forming, bending, etc.)
than described in 6.1.1 and 6.1.2.
6.2 Recommendations for above-ground installation
6.2.1 General
When thermoplastics are subject to changes in temperature, thermal movement or forces occur. The actual
forces or movement are a function of variation in temperature and cannot be calculated directly from the
coefficient of thermal expansion formula and the water temperature because hot discharges are intermittent,
resulting in a difference in temperature between the internal and the external surface of the pipe due to the
low coefficient of conductivity through the wall.
6.2.2 Installation of PE and PP pipeworks with non-removable rigid joints
PE and PP pipeworks with non-removable rigid joints (e.g. PE or PP butt-fused joints or joints with
electrofusion couplings, see 6.4.3 or 6.4.4 respectively) may be installed preventing any thermal movement. In
this case the pipework components and the supports are intended to withstand the forces which occur due to
changes in temperature and result in stress in the pipework.
Fix all pipes rigidly to the building structure and fasten each branch to the building structure by anchor
brackets (e.g. with an arrangement of fixed points as shown in Figure 15). This Figure is given for example
and does not apply for support centres (see Table 3).
For fixed point design, refer to the Note in 6.2.4.1, and carefully follow the manufacturer's instructions.
