The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for
10、 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 a
11、ll 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 are
12、 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 re
13、sponsible for identifying any or all such patent rights. ISO 13990-1 was prepared by Technical Committee ISO/TC 72, Textile machinery and machinery for dry- cleaning and industrial laundering, Subcommittee SC 3, Machinery for fabric manufacturing including preparatory machinery and accessories. This
14、 first edition of ISO 13990-1, together with ISO 13990-2 and ISO 13990-3, cancels and replaces ISO 13990:1996, of which it constitutes a technical revision.
