When the ultrasonic inspection equipment rejection rate exceeds 5.0 percent for the period between calibrations, the contractor shall check equipment calibration. If the calibration
28、is acceptable, all cartridge cases previously accepted by the equipment during this period shall be re-inspected. During re-inspection, if the reject rate exceeds 1.0 percent, all cartridge cases scheduled for re-inspection or accepted by re-inspection shall be placed aside until the cause for the e
