4.3.3 Testing.-
4.3.3.1 Dimensional control of stamped parts, Defect Code 04001). - 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 pro-
duction.
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 pro-
duction. Further, that portion of production since the last toll control
check shall be returned to the contractor for corrective action.
All tools removed from production because of some fault, may, after re-
working, 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.
4.3.3.2 Total vent hole area (alternate method), (See Dwg. 8844610),
Major defect, Code No. 06001.- Each cartridge case shall be inspected for
total vent hole area. If any cartridge case fails to comply with the require-
ment specified on the applicable drawing, it shall be classified defective and
removed from the lot.
