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. 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 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 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 responsible 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 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. ISO 13990 consists of the following parts, under the general title Textile machinery and accessories Yarn feeders and yarn control for knitting machines: Part 1: Vocabulary Part 2: Connecting dimensions for yarn feeders and yarn control devices Part 3: Dimensions for connecting and interconnection cables iv BS ISO 13990-1:2006 Licensed Copy: sheffieldun sheffieldun, na, Sat Nov 25 14:28:17 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 1 Textile machinery and accessories Yarn feeders and yarn control for knitting machines Part 1: Vocabulary Scope This part of ISO 13990 establishes a vocabulary of basic terms relating to yarn feeders and yarn control of single thread for knitting machines. The figures illustrate solely the working principles of the various types of yarn feeder and yarn control. They do not represent the only, or even the most common, designs. NOTE In addition to terms and definitions used in two of the three official ISO languages (English and French), this part of ISO 13990 gives the equivalent terms and definitions in the German language; these are published under the responsibility of the member body for Germany (DIN). However, only the terms and definitions given in the official languages can be considered as ISO terms and definitions.
