This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, a

32、t the latest by December 2008, and conflicting national standards shall be withdrawn at the latest by December 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying

33、any or all such patent rights.

Where the text in ISO 14520-1 gives the reference to “ISO 14520-1“ or “this part of ISO 14520“ this document refers only to “this document“ and is not marked by a straight line.

41、em design of gas extinguishing systems for IG-541 extinguishant (ISO 14520-15, modified) ISO 14520-1:2006 has the following foreword: ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing Internation

42、al 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,

43、 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 2. The main task of technical comm

44、ittees is to prepare 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 p

45、ossibility that some 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 14520-1 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting, Subcommittee SC 8, G

46、aseous media and firefighting systems using gas. This second edition cancels and replaces the first edition (ISO 14620-1:2000), which has been technically revised. Annex C has been extensively revised to include polymeric sheet fuel array fire tests polymethyl methacrylate (PMMA), polypropylene (PP)

47、 and acrylonitrile-butadiene-styrene (ABS). These tests are designed to more closely represent plastic fuel hazards 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 pro

48、vide means for dealing with non-standard (as opposed to geometrically regular) hazard enclosures. Also incorporated 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 saf

49、e human exposure limits. ISO 14520 consists of the following parts, under the general title Gaseous media fire extinguishing systems Physical properties and system design: Part 1: General requirements Part 2: CF3I extinguishant Part 5: FK-5-1-12 extinguishant Part 6: HCFC Blend A extinguishant Part 8: HFC 125 extinguishant Part 9: HFC 227ea extinguishant Part 10: HFC 23 extinguishant BS EN 15004-1:2008EN 15004-1:2008 (E) 8 Part 11: HFC 236fa extinguishant Part 12 IG-01 extinguishant Part 13: IG-100 extinguishant Part
