Assessment and Technical InvestigationsThe following is a summary of the assessment and technical investigations carried out on the Polypipe Terrain FUZEDrainage System.

Design Considerations

3 General3.1 Polypipe Terrain FUZE Drainage System pipes and fittings are satisfactory for use in domestic, commercialand public buildings and in installations designed in accordance with BS EN 12056-2 : 2000 and BS EN 12056-3 : 2000 for the conveyance of surface water and domestic sewage as is permitted to be

discharged into public sewers by the Public Health Act 1936 (England and Wales), and surface water and sewage asis permitted and defined by the Sewerage (Scotland) Act 1968 and the Water and Sewerage Services (NorthernIreland) Order 1973.

3.2 The average linear expansion coefficient for Polypipe Terrain FUZE Drainage pipes is 2 x 10–4 m·m–1·°C.Installations must be designed to accommodate or prevent the anticipated thermal movement as follows:

Prevention of longitudinal thermal movement3.3 Movement can be prevented by embedding the pipe (with electroweld sleeves or bushes) in concrete or by rigidfixings.

Embedment3.4 The adhesion between concrete and pipe is inadequate to prevent movement. When installed within concretefloors the movement is prevented by the use of electroweld sleeves or bushes which protrude from the external surfaceof the pipe. These fittings must be used near each branch connection. Ring-seal sockets should not be embedded inconcrete. The expansion and contraction forces created by thermal movement must be accommodated by the concrete.

Rigid installation3.5 The forces exerted on pipe supports, anchors and the structure must be considered when this approach is used.Rigid fixings are not considered suitable for pipes over 160 mm in diameter. Guidance on the load exerted on fixingsis available from the manufacturer.

Accounting for length/longitudinal movement3.6 Vertical and horizontal expansion can be catered for by the expansion socket. The product is designed to copewith the expansion equivalent to a 5 m run of pipe through a temperature change of 80°C. This product should beused in conjunction with rigid anchor fixings and sliding guide hangers. Sliding guide hangers are not provided as partof the system, but are available as proprietary products.

3.7 Thermal movement can also be accommodated by the incorporation of a deflection leg within the design of theinstallation of the system. The maximum anticipated movement is determined, and the length of the required deflectionleg appropriate to the predicted movement. Sliding supports allow the pipe expansion to occur between two fixedsupports in the structure.

4 Practicability of installationInstallation of the pipes and fittings is achieved easily providing the procedures detailed in the Polypipe Terrain FUZEDrainage brochure are strictly adhered to (see also section 14 of this Certificate).

5 Strength5.1 Polypipe Terrain FUZE pipes and fittings will have adequate resistance to the types of loading associatedwith installation and normal service conditions.

5.2 The system should be protected from impacts, for example from heavy vehicles such as fork-lift trucks used oncommercial premises.

6 Performance of joints6.1 The joints will not be adversely affected by thermal movement provided the correct provision is made.

6.2 The joints will remain watertight under conditions of pipeline movement in excess of those expected to occur innormal good drainage practice.

7 Flow characteristics7.1 A system incorporating Polypipe Terrain FUZE pipes and fittings will have satisfactory flow characteristics.Primary ventilated stack systems to BS EN 12056-2 : 2000, clause 4.3.1 and Table 1, are restricted inaccordance with clause 6.5.1 and Table 11. For flow capacity calculations, ball fittings should be considered

as having square entries.

7.2 Use of ventilation branches in a stack allows the design capacity of a 110 mm primary ventilated stack to beincreased to 8.7 l·s–1 maximum, and the 160 mm diameter to 18.1 l·s–1 maximum, thus avoiding the need foradditional ventilation (see Table 24). The stack design must be in accordance with the Certificate holder’s guidelines(see Figure 2). A ventilation branch fitting must be installed at each floor above the ground floor, even if appliances arenot connected. The ground pipe must be 160 mm in diameter and a pressure relief line must be installed at the bend atthe bottom of the stack.

8 Resistance to chemicals8.1 The system will be unaffected by those types and quantities of chemicals likely to be found in the effluentsdefined in section 3.1 of this Certificate.

8.2 Details of the chemical resistance of HDPE are given in CP 312-1 : 1973.

9 Resistance to elevated temperaturesThe system has adequate resistance to the temperatures likely to occur in the effluents defined in section 3.1 ofthis Certificate.

10 Behaviour in relation to fire10.1 In common with other plastics materials, Polypipe Terrain FUZE pipes and fittings are combustible and in a firemay ignite and burn. The pipes, adaptors and fittings are high-density polyethylene and their burning will not result inthe release of toxic gases. However, consideration should be given to the need for protective, fire-resistant ductingwhen assessing the fire risk in a building, particularly where large quantities of piping may otherwise be exposed.

10.2 In England and Wales the detailed requirements are given in Approved Document B.

10.3 In Scotland and Northern Ireland, pipes which penetrate separating or compartment walls or floors must beconstructed or protected so that, in the event of fire, the fire resistance required for the wall or floor is maintained, andthey must be fire-stopped.

11 MaintenanceSections of the system can easily be removed and replaced. The installation must be designed so that access isprovided in accordance with BS EN 12056-2 : 2000, clause ND4.

12 DurabilityIn the opinion of the BBA, when used in the context of this Product Sheet, the materials from which thecomponent parts of the pipes, adaptors and fittings are manufactured will not significantly deteriorate and thesystem will have serviceable life equivalent to PVC-U sanitary pipework systems.

Installation

13 Procedure13.1 Installation must be in accordance with the manufacturer’s literature and the recommendations given in BS EN 12056-2 : 2000 and BS EN 12056--3 : 2000 where appropriate.

13.2 End-to-end butt weld joints must be carried out under controlled conditions as follows:• pipe must be cut square and clean using a Polypipe Terrain pipe cutter• the welding plate must be clean• the required lateral pressure must be applied• appropriate heat-up and weld time should be used.

13.3 Welding procedure is as follows:• the face of each item is heated by lightly pressing the components against the heating plate for the correct period• clamping pressure is gradually increased to the required value and held for the specified period• clamps and jigs are available to ensure correct alignment of the joint.

13.4 Electroweld joints using the appropriate Polypipe Terrain welder must be carried out as follows:• the pipe end and sleeve must be kept dry at all times• the pipe is cut off at right-angles, deburred and cleaned• the pipe or fitting is inserted into the sleeve to the central register, the welder is connected to the sleeve and

operated in accordance with the manufacturer’s instructions.

13.5 Other types of connection sleeve must be butt welded to the spigot to be joined in accordance with sections13.2 and 13.3. The connection is made according to the joint type as follows:

• ring-seal socket — the pipe or fitting spigot is lubricated and pushed fully into the socket

• expansion socket(1) — the pipe is pushed the appropriate length into the socket, depending on the temperature atthe time of installation (see Table 9)

• screw-threaded fittings are connected to spigots by inserting the spigot fully into the joint and tightening the lockingcollar by hand.

(1) Expansion sockets should be protected from the ingress of dirt.

13.6 Pipes are secured by anchor brackets on hangers (not covered by this Certificate). The maximum spacing of thesupports must be ten times the pipe diameter for vertical and horizontal pipes.

Technical Investigations

14 Investigations14.1 An examination was made of data relating to:• material properties • dimensions in relation to BS EN 1519-1 : 2000 • installation• thermal shock • heat reversion • melt-flow index• resistance to pressure.

14.2 The manufacturing process was examined, including the methods adopted for quality control, and details wereobtained of the quality and composition of the materials used.
