Foreword

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 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.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

— permission of the use of two different sample preparation methods have been added in 7.2;
— the specification of applied sample preparation method, the date of the test, any deviations from the procedure, and any unusual features observed have been added in the test report in Clause 10;
— former Annexes B and C (operation of different instruments) have been removed;
— a new informative Annex B with precision data for micronaire measurements has been added;
— a new informative Annex C with precision data for comparison of the both test specimen preparation methods has been added;
— a bibliography has been added;
— grammar and linguistic consistency have been reviewed.
