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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso
.org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire
fighting, Subcommittee SC 5, Fixed firefighting systems using water.
This second edition cancels and replaces the first edition (ISO 6182-11:2003), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— The seismic requirements and testing have been removed from this document and will be addressed
in a separate standard.
A list of all the parts in the ISO 6182 series, can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

type of pipe hanger where the distance from the structure to the pipe is adjustable and usually utilizes
a metallic strip looped around the pipe for support of a load
Note 1 to entry: See Figure 1 j).

3.1.1
adjustable swivel band (loop) hanger
type of pipe hanger that is intended to accommodate support of piping at various directions in the
same plane
Note 1 to entry: See Figure 1 e).
3.2
bracket
cantilever-type pipe hanger that is attached directly to a vertical surface of the building structure
Note 1 to entry: See Figure 1 l).
3.3
building attachment component
support fixing
pipe hanger component set into the wall, such as driven fastener, expansion anchor, undercut anchor, or
cast-in insert, intended to support the pipe hanger
3.4
cast-in insert
type of building attachment component cast into the concrete at the time of pouring
Note 1 to entry: See Figure 1 m).
Note 2 to entry: Cast-in inserts can be channels, which take special threaded bolts, or internally threaded sockets,
which accept conventional bolts or rods.
3.5
ceiling flange
type of building attachment component pipe hanger that is attached directly to an overhead surface of
a building structure
Note 1 to entry: See Figure 1 k).
3.6
beam clamp
type of building attachment that is rigidly attached to both edges of the bottom flange of a
structural member
Note 1 to entry: See Figure 1 a).
3.7
C-clamp
building attachment component that grips a flange by means of a jaw and setscrew combination
Note 1 to entry: See Figure 1 q).
3.8
riser clamp
pipe attachment component intended to support vertical piping (risers) at various levels
Note 1 to entry: See Figure 1 b).
3.9
top/bottom clamp
building attachment intended to rigidly grip one edge of a top or bottom flange of a steel structural
member
Note 1 to entry: See Figure 1 d).

embraces a pipe intended to be attached directly to a building structure
Note 1 to entry: See Figure 1 c).
3.12
coupler
threaded rod coupling
threaded element used to connect the building attachment component (support fixing) to the rod

are expanded by driving an expander plug to the base of the shell or by driving the shell over the expander plug.
Note 3 to entry: 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).

assembly of components used singly or in combination with other assemblies for supporting gravity
loads of a piping system
