NATIONAL FOREWORD

This Indian Standard (First Revision) which is identical with ISO 8039 : 2014 ‘Microscopes — Values, tolerances and symbols for magnification’issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Educational Instruments and Equipment Sectional Committee and approval of the Production and General Engineering Division Council.

This standard was originally published in 2003 identical with ISO 8039 : 1997. The first revision of this standard has been undertaken to align it with the latest version of ISO 8039 : 2014.

In this revision, definitions which were part of this standard have been removed. The terms and definitions given in ISO 10934-1 shall apply.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
