This International Standard describes, with reference to ISO/R 230, both geometrical and practical tests on general purpose parallel lathes, and gives the corresponding permissible deviations which apply.
It deals only with the verification 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), or to characteristics (speeds, feeds, etc.,) which should generally be checked before testing accuracy.
