“This standard is no longer an American National Standard or an ASME-approved standard. It is available for historical reference only.”

This standard shows how to specify the general tolerances for metric dimensions without tolerance designation. The fine and medium tolerance series, are mostly applicable to machined parts, and the coarse series show tolerances for use on all types of dimensions.
