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 5923 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.
This third edition cancels and replaces the second edition (ISO 5923:1989), which has been technically revised.

Introduction
This International Standard is one of a series of other International Standards giving specifications for fire
extinguishing media in common use and which are in need of a specification for fire fighting purposes. These
specifications are designed to establish that the medium in question has at least a minimum useful fire
extinguishing capability and can therefore be reasonably sold for fire extinguishing purposes.
Requirements for media used in particular equipment will form the subject of future International Standards.
Annexes A to C of this International Standard specify methods for determining, respectively, water, oil and total
sulfur compounds contents. Annexes D to G provide important information on, and give recommendations relating
to, the safety and use of carbon dioxide, and they should be read carefully by all concerned with this medium.
INTERNATIONAL STANDARD ISO 5923:2012(E)
Equipment for fire protection and fire fighting — Fire
extinguishing media — Carbon dioxide
1 Scope
This International Standard specifies requirements for carbon dioxide for use as a fire extinguishing medium.
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.

3 Terms and definitions
For the purposes of this document, the following definition applies.
3.1
carbon dioxide
C0
chemical compound C0 used as a fire extinguishing medium
4 Requirements
Carbon dioxide shall comply with the requirements of Table 1 below, when tested by the appropriate method
of test specified in Clause 6.
Table 1 — Requirements for carbon dioxide properties
Property Requirements
Purity, o/o (VI V) min. 99,5
Water content, o/o (m/m) max. 0,015
Oil content, ppm by mass, max. 5
Total sulfur compounds content, expressed as sulfur, ppm by mass, max. 5,0
NOTE Carbon dioxide obtained by converting dry ice to liquid will not usually comply with these requirements unless it
has been properly processed to remove excess water and oil.
ISO 5923:2012(E)
5 Sampling
5.1 General
Samples of carbon dioxide needed to perform all of the tests required by this International Standard shall be
taken from the same manufacturing lot, using identical sampling procedures.
NOTE Attention is drawn to the need to design equipment for handling carbon dioxide such that it is either capable of
withstanding the pressures involved or is protected from them.
5.2 Sampling equipment
Rigid metal connections or a flexible reinforc
