The work of preparing International Standards is normally carried out through ISO technical committees. E
25、ach 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 Internati
26、onal 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 Standa
27、rds 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
28、 of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

32、ith respect to the IG-100 extinguishant. It includes details of physical properties, specification, usage and safety aspects and is applicable to systems operating at nominal pressure of 160 bar, 200 bar and 300 bar at 15 C. This does not preclude the use of other systems; however, design data for o
33、ther pressures were not available at time of publication. 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 (inc
34、luding any amendments) applies.

35、and uses 4.1 General Extinguishant IG-100 shall comply with the specification according to Table 1. IG-100 is a colourless, odourless, electrically non-conductive gas with a density approximately the same as that of air. The physical properties are given in Table 2. IG-100 extinguishes fires mainly
36、by a reduction of the oxygen concentration in the atmosphere of the hazard enclosure. Table 1 Specification for IG-100 Property Requirement Purity 99,6 % by volume, min. Water content 50 106by mass, max. Oxygen 0,1 % by volume, max. Only principal contaminants are shown. Other measurements may inclu

The extinguishant requirements per volume of protected space are shown in Table 3 for various levels of concentration. These are based on method
40、s given in EN 15004-1:2008, 7.6. The extinguishing concentrations and design concentrations for n-heptane and Surface Class A hazards are given in Table 4.
