Technical Specification
1 Description
1.1 The Harmer SML Cast Iron Drainage System
Pipes, Couplings and Fittings — Above-ground
Applications comprises cast-iron pipes, couplings,
fittings and other accessories.
1.2 The pipe and fittings are coated internally and
externally with epoxy or a primer coating. See
Table 1.

1.3 Pipes and fittings are available in the sizes
listed in Table 2 and Figure 1. Three types of
coupling (see Figure 2) are available:
• Harmer Duo coupling — available in sizes up to
300 mm. The coupling consists of a stainless-steel
collar with an EPDM gasket. The collar is
tightened by two galvanized or stainless-steel
nuts and bolts. The coupling also has an integral
continuity clip to ensure electrical continuity
through the joint. (See BBA Certificate
No 99/3650)
• Harmer Grip coupling — available in sizes up
to 200 mm. As the Harmer Duo but for use with
higher pressures
• ductile coupling — available in sizes up to
200 mm diameter, manufactured from ductile
cast iron to EN-GJS-400-15(GGG40).

1.4 Continuous quality control is excercised during
manufacture to maintain product quality and includes:
Pipes and fittings
• visual checks
• dimensional checks
• material checks
Couplings
• visual checks
• dimensional checks
• joint checks.
2 Delivery and site handling
2.1 Each pipe bears the manufacturer’s name or
mark, the nominal diameter and a code indicating
date of manufacture. Fittings are marked with the
nominal diameter and the manufacturer’s name or
mark, and a code indicating date of manufacture.
2.2 Normal care is required in handling to
prevent damage.
Readers are advised to check the validity of this Detail Sheet by either referring to the BBA’s website (www.bbacerts.co.uk) or contacting

Design Data
3 General
3.1 Harmer SML Cast Iron pipes, adaptors
and fittings are satisfactory for use in
domestic, commercial and public buildings
in accordance with BS EN 12056-1, -2 and -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 as is permitted and defined by the
Sewerage (Scotland) Act 1968 and the Water and
Sewerage Services (Northern Ireland) Order 1973.
3.2 The pipes and fittings are coated with brownred
primer (RAL 3016). A finish coat should be
applied to provide protection for external use.
4 Strength
4.1 Harmer SML Cast Iron pipes, adaptors
and fittings will have adequate resistance
to the forms of loading associated with
installation and normal service conditions.
4.2 The products should be protected from
impacts, for example, heavy vehicles, such as
fork-lift trucks used on commercial premises.
5 Performance of joints
5.1 The joints will not be adversely
affected by thermal movement when
correctly made.
5.2 The joints will remain watertight under
conditions of pipeline movement in excess of
those expected to occur in normal good drainage
practice.

6 Flow characteristics
6.1 A system comprising the Harmer SML
Cast Iron pipes, adaptors and fittings will
have satisfactory flow characteristics. Nonswept
branch connections are restricted in
accordance with BS EN 12056-2 : 2000 for
single-stack systems.
6.2 Offsets in the wet portion of a discharge stack
should be avoided. However, if the S-bend offsets
are to be fitted in this position, large radius bends
should be used (see BS EN 12056-2 : 2000).
A ventilation stack may be necessary above and
below the offset (see Figure 3).
(listed in Detail Sheet 1) must be taken into account
at the design stage.
10 Noise
In 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 Maintenance
Sections of the system can be easily removed
and replaced. Access must be provided in
accordance with BS EN 12056-2 or -3 :
2000.

12 Durability
When used within the conditions and
recommendations given in this Detail Sheet
the products will have a serviceable life
equivalent to conventional cast-iron drainage
systems. When used externally the pipes should be
painted regularly to prevent surface oxidisation.

Note 4 Offsets above highest branch connections do not require
venting.
7 Resistance to chemicals
The products will be unaffected by those
type and quantities of chemicals likely to be
found in the effluents defined in section 3.
8 Resistance to elevated temperatures
The products have adequate resistance to
the temperatures likely to occur in the
effluents defined in section 3.

Installation
13 Procedure
13.1 Installation of Harmer SML Cast Iron
Drainage System Pipes, Couplings and Fittings —
Above-ground Applications should be in
accordance with BS EN 12056-1, -2, -3 and -5 :
2000 and the manufacturer’s Specifier’s manual.
Pipes
13.2 Pipes must be adequately supported at every
connection and at a maximum spacing of 2 m for
both horizontally and vertically. In buildings of up
to five floors, downpipes must be secured against
declining by a downpipe support installed just
above the basement ceiling. In buildings higher
than five floors, an additional downpipe support
must be installed for every fifth floor.
13.3 Horizontal pipes must be fastened at every
change in direction or branch. Pipes attached to
pendula must be secured at distances of 10 m to
15 m by specific fixed-point brackets. The pipes
must be installed at a gradient of at least 20 mm
per metre.
Couplings
13.4 Installation should be carried out in accordance
with the relevant manufacturer’s instructions.
13.5 Pipe ends should be cut square and cleaned
to ensure a good fit.
13.6 For the ductile coupling, the sealing collar is
inserted, piror to the coupling. Finally, the electrical
continuity screw is tightened.
13.7 When tightening the coupling nuts and
bolts, reference must be made to the correct torque
settings specified (see Figure 2).

Technical Investigations
The following is a summary of the technical
investigations carried out on the Harmer SML Cast
Iron Drainage System Pipes, Couplings and
Fittings — Above-ground Applications.
14 Tests
Tests were carried out to determine:
• effect of elevated temperature cycling, to
BS EN 877 : 1999
• ease of jointing
• machinability.
15 Investigations
15.1 An evaluation of data was made to assess:
• system design
• resistance to chemicals
• practicability of installation
• suitability of materials
• effect of crossflow
• quality of castings
• effect of elevated temperature on pressuretightness
of joints
• compatibility with other paints
• flame resistance
• durability.
