12、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 for which a technical committee has been established has the right to be represented on that committee. I
13、nternational 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 all matters of electrotechnical standardization. International Standards are drafted in accordance with
14、 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 are circulated to the member bodies for voting. Publication as an International Standard requires approva
15、l 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 responsible for identifying any or all such patent rights. ISO 1496-2 was prepared by Technical Committe

18、eratures while being cooled by a mechanical refrigeration unit (MRU), has been added and the following tests have been renumbered; in 8.14.3, the air leakage rate requirement has been revised to not exceed 5 m3/h; clarification has been given in 8.16.1.1, 8.16.2.1, 8.12.1 and in a note to 9.4; the r
19、equirements given in Table 4 have been corrected. The opportunity was also taken for an editorial revision to update the style.
