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 14520-5 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting,
Subcommittee SC 8, Gaseous media and firefighting systems using gas.
ISO 14520 consists of the following parts, under the general title Gaseous fire-extinguishing systems —
Physical properties and system design:
— Part 1: General requirements
— Part 2: CF I extinguishant

— Part 5: FK-5-1-12 extinguishant

Part 3, 4 and 7, which dealt with FC-2-1-8, FC-3-1-10 and HCFC 124 extinguishants, respectively, have been
withdrawn, as these types are no longer manufactured.

Part 5:
FK-5-1-12 extinguishant
1Scope
This part of ISO 14520 gives specific requirements for gaseous fire-extinguishing systems, with respect to the
FK-5-1-12 extinguishant. It includes details of physical properties, specification, usage and safety aspects and
is applicable to systems operating at nominal pressures of 25 bar and 42 bar with nitrogen propellant. This does
not preclude the use of other systems.
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.

General requirements
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 14520-1 apply.
4Characteristics and uses
4.1 General
Extinguishant FK-5-1-12 shall comply with the specification according to Table 1.
FK-5-1-12 is a clear, colourless, almost odourless, electrically non-conductive gas with a density approximately
11 times that of air.
The physical properties are given in Table 2.
FK-5-1-12 extinguishes fires mainly by physical means, but also by some chemical means.
