SN ISO 6899:1984现行

Defines geometrical tests on open front mechanical power presses and gives the corresponding permissible tolerances. It is applicable to machines of general-purpose use and normal accuracy up to 2 500 kn capacity, and deals only with the verification of the 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.), or to its characteristics (speeds, feeds, etc.), which should generally be checked before the accuracy is tested.
