scope:

Describes, with reference to ISO/R 230, both geometrical and practical tests on general purpose and normal accuracy external cylindrical grinding machines with a movable table of which the swing diameter does not exceed 800 mm (32 in) and the distance between centres, 4000 mm (160 in), and also gives the corresponding permissible deviations which apply. It deals with the verification of accuracy of the machine. It does not apply to testing the running of the machine (vibrations, abnormal noises, stick-slip motion of components, etc.) or to its characteristics (speed, feeds, etc.) which should generally be checked before testing accuracy.
