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/lEC Directives, Part 2 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 1889 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 13, Composites and reinforcement fibres. This fourth edition cancels and replaces the third edition (IsO 1889:1997), of which it constitutes a minor revision. The main changes are as follows: the scope has been broadened to include all reinforcement-fibre yarns; the normative references have been updated; the reference to IsO 1886 which was in the first footnote on page 3 has been removed (isO 1886 has been withdrawn without replacement). ahtsreserved ili
