The work of preparing International Standards is normally carried out spuepues [euoeu jo uoeapag apsmpom e sl (uogezspepueas aoj uoezqueao jeuogeuapu aup) os1through ISO technical mittees. Each member body interested in a subject for which a technical mittee has been established has the right to be represented on that mittee. Internationalorganizations 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 thedifferent 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

This third edition cancels and replaces the second edition (ISO 6892-1:2016) of which it constitutes a minor revision. The changes pared to the previous edition are as follows:

correction of the title of a standard in Clause 2:correction of the designation “coefficient of determination² (°coefficient of determination” instead of “coefficient of correlation); correction of Formula (1):O u Supo- ocorrection of the references.
