13、s reserved 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 fo
14、r 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
15、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 ar
16、e 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 r
17、esponsible for identifying any or all such patent rights. ISO 14520-1 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 second edition cancels and replaces the first edition (ISO 1
18、4520-1:2000), which has been technically revised. Annex C has been extensively revised to include polymeric sheet fuel array fire tests polymethyl methacrylate (PMMA), polypropylene (PP) and acrylonitrile-butadiene-styrene (ABS). These tests are designed to more closely represent plastic fuel hazard
19、s such as may be encountered in information technology, telecommunications and process control facilities. Annex E has been re-structured to accommodate lighter-than-air gases and to provide means for dealing with non-standard (as opposed to geometrically regular) hazard enclosures. Also incorporate
20、d in this revision of ISO 14520-1 are safe personnel exposure guidelines. Annex G, recognizing physiologically based pharmacokinetic (PBPK) modelling and hypoxic guidelines to define safe human exposure limits.
