NATIONAL FOREWORD

This Indian Standard which is identical with ISO 835 : 2007 ‘Laboratory glassware - Graduated pipettes’ 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 supersedes IS 4162 (Part 1) : 1985 ‘Graduated pipettes: Part 1 General requirements (first revision)’, IS 4162 (Part 2) : 1985 ‘Graduated pipettes: Part 2 Pipettes for which no waiting time is specified (first revision)’, IS 4162 (Part 3) : 1985 ‘Graduated pipettes: Part 3 Pipettes for which a waiting time of 15 s is specified (first revision)’ and IS 4162 (Part 4) : 1985 ‘Graduated pipettes: Part 4 Blow-out pipettes (first revision)’.

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.
