Design Data

3 General3.1 Harmer SML Cast Iron pipes, adaptorsand fittings are satisfactory for use indomestic, commercial and public buildings

in accordance with BS EN 12056-1, -2 and -3 :2000 for the conveyance of surface water anddomestic sewage as is permitted to be dischargedinto public sewers by the Public Health Act 1936(England and Wales), and surface water andsewage as is permitted and defined by theSewerage (Scotland) Act 1968 and the Water andSewerage Services (Northern Ireland) Order 1973.

3.2 The pipes and fittings are coated with brown-red primer (RAL 3016). A finish coat should beapplied to provide protection for external use.

4 Strength4.1 Harmer SML Cast Iron pipes, adaptorsand fittings will have adequate resistanceto the forms of loading associated with

installation and normal service conditions.

4.2 The products should be protected fromimpacts, for example, heavy vehicles, such asfork-lift trucks used on commercial premises.

5 Performance of joints5.1 The joints will not be adverselyaffected by thermal movement whencorrectly made.

5.2 The joints will remain watertight underconditions of pipeline movement in excess ofthose expected to occur in normal good drainagepractice.

Electronic Copy

6 Flow characteristics6.1 A system comprising the Harmer SMLCast Iron pipes, adaptors and fittings willhave satisfactory flow characteristics. Non-

swept branch connections are restricted inaccordance with BS EN 12056-2 : 2000 forsingle-stack systems.

6.2 Offsets in the wet portion of a discharge stackshould be avoided. However, if the S-bend offsetsare to be fitted in this position, large radius bendsshould be used (see BS EN 12056-2 : 2000).A ventilation stack may be necessary above andbelow the offset (see Figure 3).

Figure 3 Offsets in discharge stacks

7 Resistance to chemicalsThe products will be unaffected by thosetype and quantities of chemicals likely to befound in the effluents defined in section 3.

8 Resistance to elevated temperaturesThe products have adequate resistance tothe temperatures likely to occur in theeffluents defined in section 3.

9 Properties in relation to fire9.1 Harmer SML Cast Iron pipes and fittingsare non-combustible.

9.2 The Building Regulations concerning theprevention of fire spread, eg by by fire-stopping

(listed in Detail Sheet 1) must be taken into accountat the design stage.

10 NoiseIn common with all types of pipe materials,where the products penetrate a floor or wall,separating habitable rooms, they should be

in an enclosure to limit sound transmission.

11 MaintenanceSections of the system can be easily removedand replaced. Access must be provided inaccordance with BS EN 12056-2 or -3 :

2000.

12 DurabilityWhen used within the conditions andrecommendations given in this Detail Sheetthe products will have a serviceable life

equivalent to conventional cast-iron drainagesystems. When used externally the pipes should bepainted regularly to prevent surface oxidisation.

Installation

13 Procedure13.1 Installation of Harmer SML Cast IronDrainage System Pipes, Couplings and Fittings —Above-ground Applications should be inaccordance with BS EN 12056-1, -2, -3 and -5 :2000 and the manufacturer’s Specifier’s manual.

Pipes13.2 Pipes must be adequately supported at everyconnection and at a maximum spacing of 2 m forboth horizontally and vertically. In buildings of upto five floors, downpipes must be secured againstdeclining by a downpipe support installed justabove the basement ceiling. In buildings higherthan five floors, an additional downpipe supportmust be installed for every fifth floor.

13.3 Horizontal pipes must be fastened at everychange in direction or branch. Pipes attached topendula must be secured at distances of 10 m to15 m by specific fixed-point brackets. The pipesmust be installed at a gradient of at least 20 mmper metre.

Couplings13.4 Installation should be carried out in accordancewith the relevant manufacturer’s instructions.

13.5 Pipe ends should be cut square and cleanedto ensure a good fit.

13.6 For the ductile coupling, the sealing collar isinserted, piror to the coupling. Finally, the electricalcontinuity screw is tightened.

13.7 When tightening the coupling nuts andbolts, reference must be made to the correct torquesettings specified (see Figure 2).
