4. The tolerance of position that controls the location of the pattern of balls with respect to datums A and B.

For 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.

fff(5)

5. The tolerance of position that controls the location of the balls within the matrix with respect to each other.

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.
