7、eral Test Method Standard No. 601. Five (-5)- readings shall be taken on each part using the hardness scale specified in MIL-STD-417. The median value of the five readings shall be obtained by arranging the value of the readings from lowest to highest. The median reading will be the third (center) v
8、alue in the numerically arranged readings. If the median hardness of any part fails to comply with the applicable hardness requirement (See MIL-STD-417) for the grade number the lot represented by the sample parts shall be rejected. (:Non-destructive test). 4.5.2 Dimensional control of stamped parts
9、.-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 shall be dimensionally in- spected to qualify the tool used in the stamping process for use in production. In addition, a random samp
10、le of five (5) parts shall be selected from the last portion of each hours 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 an
11、y defective parts are found when inspection is per- formed 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 returned to the contractor for corrective action. 11 Provided by
