IS/ISO 603 : Part 1 : 1999 : Bonded Abrasive Products - Dimensions Part 1 Grinding Wheels for External Cylindrical Grinding Between Centres

NATIONAL FOREWORD

This Indian Standard (Part 1) which is identical with ISO 603-1 : 1999 'Bonded abrasive products - Dimensions - Part 1: Grinding wheels for external cylindrical grinding between centres' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Abrasives Sectional Committee and approval of the Production and General Engineering Division Council.

This standard was originally published as IS 2324 (Part 2) : 1963 'Bonded abrasive grinding wheels: Part 2 Dimensions' and revised in 1971 and further revised in 1985 in two parts. The committee has now decided to adopt this standard in a single number as IS/ISO 603-1 : 1999 and IS/ISO 603-2 : 1999 by superseding IS 2324 (Part 2) : 1985.

After the publication of this standard, IS 2324 (Part 2) : 1985 'Bonded Abrasive Grinding wheels: Part 2 Dimensions' shall be treated as withdrawn.

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.
