NATIONAL FOREWORD

This Indian Standard (First Revision) which is identical with ISO 4703 : 2001 ‘Test conditions for surface grinding machines with two columns — Machines for grinding slideways — Testing of the accuracy’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Machine Tools, Machine Tool Elements and Holding Devices Sectional Committee and approval of the Production and General Engineering Division Council.

This standard was first published in 1994 by adopting ISO 4703 : 1984. Since ISO has revised its standard, this revision has been taken up to align with the latest edition of ISO 4703. In this revision, besides other changes, the terminology used for the principal components of the machine and the designations of the axes with reference to ISO 841 has been added.

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.
