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 3. 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 International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 11601 was prepared by Technical Committee ISO/TC 21,Equipment for fire protection and fire fighting, Subcommittee SC 2,Manually transportable fire extinguishers.

It is applicable to wheeled fire extinguishers with a total mass when fully charged of greater than 25 kg but not more than 450 kg. 2Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

At present, the types of wheeled fire extinguishers are as follows: ?water-based; ?powder; ?carbon dioxide; ?clean agent. NOTEIn some countries, the manufacture and use of clean agents is regulated by the Montreal Protocol or by national regulations. 4.2Water-based wheeled fire extinguishers may contain plain water, or water with additives such as wetting agents, viscosity-increasing agents, flame-retardant, or foaming agents, etc. NOTEAt present there are no International Standards covering additives added to water to produce antifreeze, wetting or other special characteristics. 4.3Powders may be of the “BC“ or “ABC“ types, or may be specially prepared for Class D fires. 4.4Wheeled fire extinguishers may have two extinguisher bodies per axle. Each extinguisher body may contain the same or a different extinguishing medium provided they are compatible with each other. 5Extinguishing media, propellants and fill densities 5.1Extinguishing media 5.1.1Carbon dioxide Carbon dioxide used in wheeled fire extinguishers shall comply with ISO 5923. 5.1.2Clean agents Clean agents used in wheeled fire extinguishers shall comply with ISO 7201-1 or ISO 14520-1.
