BS EN 15004-10:2008EN 15004-10:2008 (E) 5 Foreword of ISO 14520-15:2005 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 techn

25、ical 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

26、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 In

27、ternational 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

28、may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14520-15 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

32、nguishing systems, with respect to the IG-541 extinguishant. It includes details of physical properties, specification, usage and safety aspects and is applicable to systems operating at nominal pressure of 150 bar, 200 bar and 300 bar at 15 C. This does not preclude the use of other systems; howeve

35、. 4 Characteristics and uses 4.1 General Extinguishant IG-541 shall comply with the specification according to Table 1. IG-541 is a colourless, odourless, electrically non-conductive gas with a density approximately the same as that of air. It is an inert gas mixture consisting nominally of 52 % nit

36、rogen, 40 % argon and 8 % carbon dioxide, with the following mixture specification (based on 8 % carbon dioxide with tolerance of 5 %): a) Carbon dioxide: range of 7,6 % to 8,4 %; b) Argon: range of 37,2 % to 42,8 %; c) Nitrogen: range of 48,8 % to 55,2 %. NOTE Individual container or batch analysis

37、 is based on carbon dioxide measurement only. The physical properties are given in Table 2. IG-541 extinguishes fires by a reduction of the oxygen concentration in the atmosphere of the hazard enclosure.
