9、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 for which a technical
10、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 all matters of elect
11、rotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires ap
12、proval by at least75% of the member bodies casting a vote. International Standard ISO11861 was prepared by Technical Committee ISO/TC38, Textiles, Subcommittee SC12, Textile floor coverings. Annex A forms a normative part of this International Standard.iv blankBSISO 11861:1999 BSI 04-2000 1 1 Scope
