7、O (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 co
8、mmittee 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 electro
9、technical 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 circulated to the me
10、mber 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 responsible for identif
11、ying any or all such patent rights. ISO 8116-2 was prepared by Technical Committee ISO/TC 72, Textile machinery and accessories, Subcommittee SC 3, Machinery for fabric manufacturing including preparatory machinery and accessories. This third edition cancels and replaces the second edition (ISO 8116
12、-2:1995), which has been technically revised. ISO 8116 consists of the following parts, under the general title Textile machinery and accessories Beams for winding: Part 1: General vocabulary Part 2: Warpers beams Part 3: Weavers beams Part 4: Test methods and quality classification of flanges for w
