each ball there is a cylindrical tolerance zone eee perpendicular to datum C and located on true position with
respect to datums A and B as defined by e. The axis perpendicular to datum C of each ball must lie within
this tolerance zone.
For each ball there is a cylindrical tolerance zone fff perpendicular to datum C and located on true position
as defined by e. The axis perpendicular to datum C of each ball must lie within this tolerance zone. Each
tolerance zone fff in the array is contained entirely in the respective zone eee above The axis of each ball
must lie simultaneously in both tolerance zones.
