The work o
15、f 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. International organizations, governmental and non-governmenta
16、l, 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 the rules given in the ISO/IEC Directives, Part 2. The main
17、 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 approval by at least 75 % of the member bodies casting a vote. Atte
18、ntion 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 2418 was prepared by the Physical Test Commission of the International Union of Leather Technologists
19、 and Chemists Societies (IUP Commission, IULTCS) in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 289, Leather, the secretariat of which is held by UNI, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
20、The Chemical and Fastness Test Commissions were consulted in the preparation of this standard. The locations of the samples are identical to those given in IUP 2 published in J. Soc. Leather Trades Chemists 42, pp. 382-385, (1958) and IUC 2 published in J. Soc. Leather Trades Chemists 49, pp. 6-8, (
21、1965). IUP 2 was declared an official method in 1959 and IUC 2 in 1965. Updated versions were published in J. Soc. Leather Tech. Chem. 82, p. 194, (1998) and further revisions were published in J. Soc. Leather Tech. Chem. 84, p. 303, (2000) and reconfirmed as official methods in March 2001. This edi
22、tion differs slightly in the text and includes tolerances for measurements but the locations of the samples are identical. This second edition cancels and replaces the first edition (ISO 2418:1972), which has been technically revised. SANS 2418:2009This s tandard may only be used and printed by appr
