NATIONAL FOREWORD

This Indian Standard (Part 1) which is identical with ISO 11090-1 : 2014 ‘Test conditions for die sinking electro-discharge machine (die sinking EDM) — Testing of the accuracy — Part 1: Single-column machines (cross-slide table type and fixed-table type)’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Machine Tools, Machine Tool Elements and Holding Devices Sectional Committee and approval of the Production and General Engineering Division Council.

This Indian Standard is published in two parts. The other part in this series is:

Part 2 Double-column machines (slide-head type)

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’ 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.
