IS 11468 : 2012/ISO 1769 : 1975 Laboratory Glassware - Pipettes - Colour Coding

Reaffirmed 2022

NATIONAL FOREWORD

This Indian Standard (First Revision) which is identical with ISO 1769 : 1975 'Laboratory glassware - Pipettes - Colour coding' 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.

In order to identify and facilitate sorting one-mark and graduated pipettes from a large batch by the analyst or the unskilled worker' colour coding system may be adopted. This standard was first published in 1985 with a view to harmonize the then already existing coding systems and to align them with the International Standard. During this revision, the Committee felt that it would be more convenient to prepare this standard by adoption of ISO 1769 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.
