This International Standard specifies, with reference to ISO 230-1, both geometric and machining tests on general purpose, normal accuracy, surface grinding machines with reciprocating table and vertical grinding wheel spindle. It also specifies the applicable tolerances corresponding to the above-mentioned tests. This International Standard is not applicable to surface grinding machines with fixed or rotating tables or to machines having longitudinal traverse of the wheel head. This International Standard deals only with the verification of the geometric accuracy of the machine. It does not apply to the testing of the machine operation (vibrations, abnormal noises, stick-slip motion of components, etc.) nor to the checking of its characteristics (such as speeds, feeds, etc.), which should generally be checked before testing the accuracy
