Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 6182-11 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting,
Subcommittee SC 5, Sprinkler and water spray extinguishing systems.
ISO 6182 consists of the following parts, under the general title Fire protection — Automatic sprinkler systems:
 Part 1: Requirements and test methods for sprinklers
 Part 2: Requirements and test methods for wet alarm valves, retard chambers and water motor alarms
 Part 3: Requirements and test methods for dry pipe valves
 Part 4: Requirements and test methods for quick-opening devices
 Part 5: Requirements and test methods for deluge valves
 Part 7: Requirements and test methods for early suppression fast response (ESFR) sprinklers
 Part 9: Requirements and test methods for water mist nozzles
 Part 11: Requirements and test methods for pipe hangers
The following part is under preparation:
 Part 10: Requirements and test methods for domestic sprinklers

ISO 6182-11:2003(E)
3.10
driven fastener
type of building attachment component driven into solid concrete or structural steelwork by means of a special
tool, usually powder actuated, and can have female or, usually, male thread linked to the rod by means of a
coupler
3.11
expansion anchor
type of building attachment component set into the ceiling or wall of the building structure in self-drilled or pre-
drilled cylindrical holes; ceiling fixings usually “deformation-controlled” internally threaded socket anchors,
which are expanded by driving an expander plug to the base of the shell or by driving the shell over the
expander plug
NOTE Fixings for walls can be socket anchors or can be “torque-controlled” anchors, either through-bolts (where an
expander clip is expanded by the tightening of the bolt) or sleeve anchors (where the sleeve is expanded by the tightening
of the bolt).
3.13
hanger
assembly of components used singly or in combination with other assemblies for supporting pipework
NOTE A hanger can comprise a building attachment component (support fixing), coupler, rod or equivalent and pipe
attachment component as shown in Figure 2, or a simple bracket and building attachment component (support fixing) as
indicated in Figure 3.
3.14
non-heat sensitive material
material whose measured tensile strength at (540 ± 10) °C is at least 90 % of the value measured at
(20 ± 5) °C
3.15

3.18
undercut anchor
type of building attachment component set into the ceiling or wall of the building structure in self-drilled or
pre-drilled undercut holes
NOTE The setting of the anchor, usually by hammering a sleeve over an outwardly tapered element, forces the
sleeve out into the undercut shape forming a mechanical interlock with the base material. These anchors are intended for
tension zones of concrete, i.e. cracked concrete.
4 Product consistency
It shall be the responsibility of the manufacturer to implement a quality control programme to ensure that
production continuously meets the requirements of this part of ISO 6182 in the same manner as the originally
tested samples.
5 Materials and rod sizes
5.1 Materials
Hangers and their components shall be made of ferrous or other non-heat-sensitive materials.
5.2 Rod sizes
5.2.1 Hangers and their components shall be provided with rod sizes in accordance with Table 1 unless
otherwise stated in 5.2.2 to 5.2.4.
5.2.2 8-mm hanger rod sizes may be used in countries where permitted by National Standards for use with
pipe sizes up to and including DN 50. 8-mm hanger rods shall meet the load requirements of Table 1 for a
pipe size of DN 50.
5.2.3 Hanger rod sizes designated in Table 1 are the nominal diameters associated with machined threads.
The diameter of a rod provided for with a rolled thread shall be not less than the root diameter of the thread.
5.2.4 Some hanger assemblies, such as powder-driven (pyrotechnic) fasteners and 6-mm and 8-mm size
expansion shells require the use of an increaser coupling to attach to nominal 10-mm size rod. The increaser
couplings provided by the manufacturer shall have sufficient strength to support the test loads applicable to
the maximum permitted pipe size.
5.3 Ceiling flanges
Ceiling flanges for pipe sizes up to DN 50 shall have at least two supporting screw holes. For pipe sizes of up
to DN 200 (NPS 8), no less than three supporting screw holes shall be provided.
6 Material thicknesses
6.1 Uncoated material thicknesses
6.1.1 Unprotected flat steel, no less than 3 mm thick, is acceptable for use as a clevis-type hanger, band
hanger, adjustable swivel loop hanger and for other flat iron hangers, if the hanger is at least 25 mm wide and
if the hanger exhibits strength values of at least 150 % of the required test load specified in Table 1.
6.1.2 A C-clamp formed of a double thickness, no less than 3 mm thick, unprotected steel so as to form a
6 mm thick section is acceptable if the clamp exhibits strength value of at least 150 % of the required test load
specified in Table 1.
