The contractor shall resupp
19、ly the item facsimilies when it is deter- mined by the Government that the facsimilies are no longer represen- tative enough of the product to make it unidentifiable to the con- tractor inspection personnel, or it is not functioning in the neces- sary manner and cannot be corrected satisfactorily. T
20、hese standards should be representative of defects actually found or anticipated. They should be inert and readily identifiable to the Government to ensure recovery should they be inadvertently introduced into pro- duction. Simulated defect standards used to verify the following verified inspections
21、 should be constructed and identified in such a manner that they are not readily recognizable to the contractor inspection personnel as defect standards, so that their number, time, and sequence of introduction into the inspection cycle is known only to those personnel responsible for checking the a
22、ccuracy of. the operation. Adequacy o the standards shall be verified at feast once each shift, Standards should be used.
