This International Standard specifies, with reference to ISO/R 230, geometrical tests for open front mechanical power presses and gives the corresponding permissible tolerances.
This International Standard is applicable to machines of general purpose use and normal accuracy up to 2 500 kN capacity which is the biggest press standardized in ISO 6898.
This International Standard deals only with the checking of accuracy of the machine. It does not apply to the testing of the running of the machine (vibrations, abnormal noises, stick-slip motion of components, etc.) nor to its characteristics (speeds, feeds, deflection under load, etc.) which should generally be checked before testing accuracy.
