NATIONAL FOREWORD

This Indian Standard (First Revision) which is identical with ISO 11670 : 2003 ‘Lasers and laser-related equipment — Test methods for laser beam parameters — Beam positional stability’ 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 2000. This revision has been undertaken to align it with the latest version of ISO 11670 : 2003.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminology and 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.
