Summary: This standard specifies the principle of acceptance of smooth workpiece size (500mm ~ 10000mm), acceptance limit, the principle of selection of measurement equipment, the measurement equipment to allow the value of uncertainty and arbitration. This standard applies to product processing, final inspection and other processes, the tolerance level of 1 to 18 (ITl ~ IT18), the nominal size of 500mm ~ 10000mm smooth workpiece size inspection. This standard also applies to the general tolerances, extending the size of the tolerance test.
