scope:

This document specifies, with reference to ISO 230-1, geometrical tests on general purpose and normal accuracy pillar type vertical drilling machines. This document also specifies the applicable tolerances corresponding to the above­-mentioned tests.

This document covers only with the verification of accuracy of the machine.

This document does not apply to the testing of the machine operation (vibrations, abnormal noises, stick-slip motion of components, etc.) or to machine characteristics (such as speeds and feeds), which are generally checked before testing of machine accuracy.
