4.6.2 Visual and dimensional inspection. Visual and dimensional inspection shall consist of those inspections
specified in table II.
4.6.2.1 Sampling plan. A sample of five packages shall be randomly selected. If one or more defects are found,
the inspection lot shall be screened and the defective packages removed. A new sample of five packages shall be
randomly selected. If any defects are found in the second sample, the inspection lot shall be rejected and shall not
be supplied to the capacitor specification.
4.6.2.2 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 re-inspection. Such lots shall be separate from new lots and clearly identified
as re-inspected lots.
4.6.2.3 Disposition of sample units. Sample units that have passed all the inspections specified in table II may be
delivered on the contract, provided the lot is accepted.
4.6.3 Functional inspection. Functional inspection shall consist of the tests specified in table III.
4.6.3.1 Sampling plan. Sampling plans shall be as follows:
a. One sample unit for the rough handling test shall be selected whenever the design of the item or packaging is
changed.
b. For unit packs requiring waterproof or water-vapor proof barriers, five sample units for the leakage test shall
be selected daily at random from the first lot processed each day. Five additional samples shall be selected
at random from the day's total production.
c. The leakage test shall also be performed following the rough handling test on unit packs requiring waterproof
or water-vapor proof barriers. Five sample units or the number of units contained within the shipping
container (if less than five) shall be selected.
4.6.3.2 Failures. One or more failures shall be cause for rejection of the lot.
4.6.3.3 Disposition of sample units. Sample units that have passed the inspections specified in table III may be
delivered on the contract if the lot is accepted and opened packs have been reprocessed.
4.6.3.4 Noncompliance. If a sample fails to pass the inspections specified in table III, the contractor shall take
corrective action on the materials or processes or both, as warranted, on all units, and intermediate and exterior
(shipping) packs that can be corrected and that were processed under essentially the same conditions, with
essentially the same materials, and that are considered subject to the same failure. Acceptance of the unit,
intermediate, and exterior packs shall be discontinued until corrective action has been taken and the applicable
inspections specified in table III have been repeated on additional sample units (all inspections or the inspection that
the original sample failed shall be at the option of the Government). Inspections specified in table III may be
reinstituted; however, final acceptance shall be withheld until the re-inspection in accordance with table III has shown
that the corrective action was successful. In the event of failure after re-inspection, information concerning the failure
and corrective action taken shall be furnished to the administrative contracting officer.
4.7 Methods of inspections and tests.
4.7.1 Visual and dimensional inspections. Unit, intermediate, and exterior packs shall be examined to verify that
the materials, designs, methods, physical limitations, marking, and workmanship are in accordance with the
