4.6.1.2.2 Rejected lots. If an inspection lot is rejected, the manufacturer may rework it to correct the
defects, or screen out the defective units, and resubmit for reinspection. Resubmitted lots shall be
inspected using tightened inspection and shall not thereafter be tendered for acceptance unless the former
rejection or requirement of correction is disclosed. Such lots shall be separate from new lots and shall be
clearly identified as reinspected lots.
4.6.1.2.3 Disposition of sample units. Sample units, which have passed the entire group A inspections,
may be delivered on the contract if the lot is accepted and the sample units are still within the specification
tolerances.
4.6.2 Periodic inspection. Periodic inspection shall consist of group B. Except where the results of
these inspections show noncompliance with the applicable requirements (see 4.6.2.1.3), delivery of
products, which have passed group A inspection shall not be delayed pending the results of these periodic
inspections.
