4.3.3.1 Dimensional control of stamped parts.- In place of the normal
sampling associated with the Classification of Defects, and with the approval
of the Contracting Officer, a sample of at least ten (10) parts may be dimensionally
inspected to qualify the tool used in the stamping process for use in production.
In addition, a random sample of five (5) parts shall be selected from the last
portion of each hour's production for dimensional inspection as a control of the
tool during production.
If any defective parts are found during qualification of the tool, the
tool producing the defective part shall not be used in production.
If any defective parts are found when inspection is performed for control
of the tool, the tool producing the defective part shall be removed from production.
Further, that portion of production since the last tool control check shall be re-
turned to the contractor for corrective action.
All tools removed from production because of some fault, may, after reworking,
be returned to production providing they pass the qualification test above. The
contractor may request a change of inspection frequency providing he presents objective
evidence to the Contracting Officer to substantiate the request.
