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.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of document:
⎯ an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
⎯ an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
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/TS 11602-1 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire
fighting, Subcommittee SC 2, Manually transportable fire extinguishers.
This first edition of ISO/TS 11602-1 cancels and replaces ISO 11602-1:2000, of which it constitutes a
technical revision.
ISO 11602 consists of the following parts, under the general title Fire protection — Portable and wheeled fire
extinguishers:
⎯ Part 1: Selection and installation [Technical Specification]
⎯ Part 2: Inspection and maintenance [Technical Specification]

Introduction
This part of ISO 11602 presents a limited number of provisions for the selection and installation of portable
and wheeled fire extinguishers, in the knowledge that different countries have particular environments and
climates which can affect the size, shape and occupancy of buildings.
A country's specific building configurations can affect the selection and installation of fire extinguishers;
therefore, this part of ISO 11602 could be reinforced in respect of fire-extinguishing performance
characteristics in the presentation of a general-purpose standard.
It is proposed that further investigation be undertaken in light of the above for the purposes of a future revision
of this part of ISO 11602.
TECHNICAL SPECIFICATION ISO/TS 11602-1:2010(E)

Fire protection — Portable and wheeled fire extinguishers —
Part 1:
Selection and installation
1 Scope
This part of ISO 11602 gives requirements for the selection and installation of portable and wheeled fire
extinguishers. It is intended as a companion to ISO/TS 11602-2.
Portable fire extinguishers are a first line of defence against fires of limited size. They are needed even if the
property is equipped with automatic sprinklers, standpipe and hose, or other fixed protection equipment.
This part of ISO 11602 is not applicable to permanently installed systems for fire extinguishment, even though
portions of such systems may be portable (such as hose and nozzles attached to a fixed supply of
extinguishing media).
Its requirements are minimum requirements. The use of larger, higher-rated or greater numbers of
extinguishers will, in general, improve protection.
Extinguishers for use on board aircraft, watercraft and vehicles are outside the scope of ISO 11602.

references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 7165, Fire fighting — Portable fire extinguishers — Performance and construction
ISO 8421-1, Fire protection — Vocabulary — Part 1: General terms and phenomena of fire
ISO 11601, Fire fighting — Wheeled fire extinguishers — Performance and construction
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 8421-1 and the following apply.
3.1
clean agent
electrically non-conductive gaseous or vaporizing fire extinguishant that does not leave a residue upon
vaporization
[ISO 7165:2009, 3.5]
3.2
film-forming foam
extinguishing media comprising the aqueous film-forming foam (AFFF) and film-forming fluoroprotein (FFFP)
foam types, and including grades suitable for polar solvents (water-soluble flammable liquids) and those not
suitable for polar solvents
3.3
fire extinguisher
extinguisher
appliance containing an extinguishing medium which can be discharged and directed onto a fire by the action
of internal pressure
NOTE 1 The internal pressure may be provided by
⎯ a stored pressure (pressurization of the extinguishing medium container at the time of charging), or
⎯ a gas cartridge (pressurization at the time of use through the release of gas from a separate cylinder into the medium
container).
NOTE 2 Adapted from ISO 7165:2009, definition 3.11.
3.4 Hazard classes
3.4.1
class A hazard
occupancies or fuel sources where Class A fires, involving materials such as wood, cloth, paper, rubber and
many plastics, may be expected to develop
3.4.2
class B hazard
fuel sources where Class B fires, involving materials such as oils, greases and paints, may be expected to
develop
3.4.3
class C hazard
fuel sources where Class C fires, involving materials such as natural and propane gas, may be expected to
develop
3.4.4
class D hazard
fuel sources where Class D fires, involving materials such as magnesium, sodium and potassium, may be
expected to develop
3.4.5
class F hazard
fuel sources where Class F fires, involving materials in cooking appliances such as combustible cooking
media (vegetable or animal oils and fats), may be expected to develop
3.5 Hazard types (see also Annex A)
3.5.1
high hazard
location where the total amount of Class A combustibles and Class B flammables present, in storage,
production use and/or finished product, is over and above those expected under moderate hazard
occupancies
3.5.2
low hazard
location where the total amount of Class A combustible materials, including furnishings, decorations, and
contents, is of minor quantity
2 © ISO 2010 – All rights reserved

NOTE This classification anticipates that the majority of items contained are either non-combustible or so arranged
that a fire is not likely to spread rapidly. Small amounts of Class B flammables used for duplicating machines, art
departments, etc., are included provided that they are kept in closed containers and safely stored.
3.5.3
moderate hazard
location where the total amount of Class A combustibles and Class B flammables are present in greater
amounts than expected under low hazard occupancies
3.6
inspection
brief examination to ensure that an extinguisher is available and will operate
NOTE This is intended to give reasonable assurance that the extinguisher is fully charged and operable. This is done
by seeing that it is in its designated place, that it has not been actuated or tampered with, and that there is no obvious
damage or condition to prevent its operation.
3.7
maintenance
thorough examination of the extinguisher
NOTE This is intended to give maximum assurance that an extinguisher will operate effectively and safely. It includes
a thorough examination and any necessary repair or replacement. It will normally reveal if hydrostatic testing is required.
3.8
portable fire extinguisher
fire extinguisher that is designed to be carried and operated by hand and that, in working order, has a mass of
not more than 20 kg
NOTE Subject to local acceptance, extinguishers having a total mass of 25 kg when fully charged are permitted.
[ISO 7165:2009, 3.15]
3.9
rating
comparative number associated with the classification assigned to an extinguisher and indicative of its
capability in the extinguishment of a standard fire
3.10
travel distance
distance a person must travel from any point to the closest appropriate extinguisher
3.11
water-type extinguisher
fire extinguisher which contains a water-based medium, such as water, aqueous film-forming foam (AFFF) or
film-forming fluoroprotein (FFFP) foam and/or antifreeze
3.12
wheeled extinguisher
fan appliance on wheels having a total mass of more than 20 kg but not greater than 450 kg, which is
designed to be transported to the fire and operated by one person
NOTE See ISO 11601.
4 Classifications, ratings and performance of extinguishers
4.1 Extinguishers are classified for use on certain classes of fires and rated for relative extinguishing
effectiveness by testing laboratories. This is based on the classification of fires and the fire-extinguishing
potentials as determined by fire tests.
4.2 The classifications are as follows:
⎯ Class A: fires involving solid materials, usually of an organic nature, in which combustion normally
takes place with the formation of glowing embers;
⎯ Class B: fires involving liquids or liquefiable solids;
⎯ Class C: fires involving combustible gases;
⎯ Class D: fires involving combustible metals;
⎯ Class F: fires involving combustible cooking media (vegetable or animal oils and fats) in cooking
appliances.
4.3 The classification and rating systems referenced in this part of ISO 11602 are those specified in
ISO 7165 and ISO 11601.
4.4 Extinguishers conformant with this part of ISO 11602 shall also be in accordance with ISO 7165 and
ISO 11601.
4.5 The identification of the certification organization, the fire-extinguishing classification and rating and the
performance standard that the extinguisher meets are clearly marked on each extinguisher.
5 General requirements
