NATIONAL FOREWORD

This Indian Standard (Third Revision) which is identical with ISO 1042 : 1998 ‘Laboratory glassware - One-mark volumetric flasks’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Glass, Glassware and Laboratoryware Sectional Committee and approval of the Chemical Division Council.

This standard was first published in 1958 and subsequently revised in 1975. However keeping in view the trend at the level of International Organization for Standardization followed in ISO 1042 : 1998 this standard was further revised in 2006. During this revision, the Committee felt that it would be more convenient to prepare this standard by adoption of ISO 1042 on dual number basis.

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.
