4.4.1.2.2 Rejected lots. If an inspection lot is rejected, the contractor 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. Such lots shall be
separated from new lots and shall be clearly identified as reinspected lots.
4.4.2 Periodic inspection. Periodic inspection shall consist of group B. Except where the results of these inspections show
noncompliance with the applicable requirements (see 4.4.2.1.2), delivery of products which have passed group A shall not be
delayed pending the results of these periodic inspections.
4.4.2.1 Group B inspection. For individual procurements involving small quantities of antennas, Group B testing shall be at the
option of the acquiring activity (see 6.4) and of the procurement contract (see 6.2). Group B inspection shall consist of the tests
specified in table IV, in the order shown. Group B inspection shall be made on one sample unit per contract, unless otherwise
specified, which has been subjected to and passed group A inspection.
