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further three years, revised to become an International Standard, or withdrawn.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International Standard or be withdrawn.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 11602-2 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 11602-2 cancels and replaces ISO 11602-2:2000, 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 inspection and maintenance 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 inspection and maintenance 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 11602-2:2010(E)

Fire protection — Portable and wheeled fire extinguishers —
Part 2:
Inspection and maintenance
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 11602-1.
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).
Extinguishers for use on board aircraft, watercraft and vehicles are outside the scope of ISO 11602.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 5923, Fire protection — Fire extinguishing media — Carbon dioxide
ISO 7201-1, Fire protection — Fire extinguishing media — Halogenated hydrocarbons — Part 1:
Specifications for halon 1211 and halon 1301
ISO 7201-2, Fire extinguishing media — Halogenated hydrocarbons — Part 2: Code of practice for safe
handling and transfer procedures of halon 1211 and halon 1301
ISO 8421-1, Fire protection — Vocabulary — Part 1: General terms and phenomena of fire
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
closed recovery system
system that provides for the transfer of media between extinguishers, supply containers, and recharge and
recovery containers so that the escape of media to the atmosphere is minimized
3.3
competent person
person with the necessary training and experience and with access to the requisite tools, equipment, parts
and information (including the manufacturer's service manual) to be capable of carrying out the inspection,
maintenance and recharging procedures of this part of ISO 11602
3.4
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
3.5
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 See ISO 7165.
NOTE 2 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 3 Adapted from ISO 7165:2009, definition 3.11.
3.6
high-pressure cylinder
cylinder having a service pressure higher than 2,5 MPa at 20 °C
3.7
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.
3.8
low-pressure cylinder
cylinder having a service pressure of 2,5 MPa or lower at 20 °C
3.9
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.
