27、chnical Committee CEN/TC 191 “Fixed firefighting systems”, the secretariat of which is held by BSI. This document is currently submitted to the Unique Acceptance Procedure. The text of the International Standard ISO 14520-14:2005 from Technical Committee ISO/TC 21 “Equipment for fire protection and
28、fire fighting“ of the International Organization for Standardization (ISO) has been taken over as a European Standard by Technical Committee CEN/TC 191 “Fixed firefighting systems“, the secretariat of which is held by BSI, with common modifications which are indicated by a straight line in the margi

The work of preparing International Standards is norm
36、ally 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 t
37、he 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
38、 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
39、 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 14520-14 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting, Subcommittee SC 8, Gaseous media and fi
40、refighting systems using gas. This second edition cancels and replaces the first edition (ISO 14520-14:2000), which has been technically revised. ISO 14520 consists of the following parts, under the general title Gaseous media fire extinguishing systems Physical properties and system design: Part 1:

It includes details of physical properties, specification, usage and safety aspects and
44、 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; however, design data for other pressures were not available at time of publication. 2 Normative references The following referenced documents are indispen
45、sable 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. prEN 15004-1:2007, Fixed firefighting systems Gas extinguishing systems - Design installation an
46、d maintenance (ISO 14520-1, modified) 3 Terms and definitions For the purposes of this document, the terms and definitions given in prEN 15004-1:2007 apply. 4 Characteristics and uses 4.1 General Extinguishant IG-55 shall comply with the specification according to Table 1. IG-55 is a colourless, odo
47、urless, electrically non-conductive gas with a density approximately the same as that of air. It is an inert gas mixture consisting nominally of 50 % argon and 50 % nitrogen with the following mixture specification. a) Argon: range of (50 5) %. b) Nitrogen: range of (50 5) %. The physical properties
48、 are given in Table 2. IG-55 extinguishes fires by a reduction of the oxygen concentration in the atmosphere of the hazard enclosure.
