NATIONAL FOREWORD

This Indian Standard (Part 2) (First Revision) which is identical with ISO 230-2 : 2014 ‘Test code for machine tools — Part 2: Determination of accuracy and repeatability of positioning of numerically controlled axes’ 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 1997. This revision has been taken up to align with the latest version of ISO Standard.

This standard is issued in nine parts. Other parts are:

Part 1 Geometric accuracy of machines operating under no-load or quasi-static conditions

Part 3 Determination of thermal effects

Part 4 Circular tests for numerically controlled machine tools

Part 5 Determination of the noise emission

Part 6 Determination of positioning accuracy on body and face diagonals (diagonal displacement tests)

Part 7 Geometric accuracy of axes of rotation

Part 8 Vibrations

Part 9 Estimation of measurement uncertainty for machine tool tests according to series ISO 230, basic equations

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.
