The terms and definitions given in this International Standard have been confined to those parts of the spinning machine which are specific to open-end yarn production technology. Terms and definitions which relate to machine parts for which definitions appear elsewhere, for example in ISO 477 and ISO 2205, are not included. NOTE — In addition to terms given in the three official ISO languages (English, French and Russian), this International Standard also gives in annexes the equivalent terms in German and Italian; these terms have been included at the request of ISO/TC 72 and are published under the responsibility of the committee members of Germany, F.R. (DIN) and of Italy (UNI). However, only the terms and definitions given in the official languages may be considered as ISO terms and definitions.
