NATIONAL FOREWORD

This Indian Standard (Part 2) which is identical with ISO 8655-2 : 2002 ‘Piston-operated volumetric apparatus — Part 2: Piston pipettes’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Glass, Glassware and Laboratoryware Sectional Committee and approval of the Chemical Division Council.

This standard specifies the requirements, maximum permissible errors, requirements for marking and information to be provided for users, for air-displacement (type A) and positive-displacement (type D) single-channel and multi-channel piston pipettes, complete with their selected tip(s) and any other essential, consumable parts, designed to deliver their specified nominal volume.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies 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’ appears 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.
