Other parts in this series are: Part 1 Single column type machines The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards.

The corresponding Indian Standard which is to be substituted in its place is listed below along with its degree of equivalence for the edition indicated. International Standard Corresponding Indian Standard Degree of Equivalence ISO 230-1:1996 Test code for machine tools Part 1: Geometric accuracy of machines operating under no-load or finishing conditions.
