4.5.4 Periodic inspection. Periodic inspection shall consist of the inspections specified in table IV
and shall be made on three clamps which have been subjected to and passed the sampling tests. The
following details shall apply:
a. Periodic control tests shall be performed once every 26 calendar weeks, if there is a
production run.
b. Parts shall be as representative as possible of the production lots for the time period that they
represent (for example, parts shall be from different lots, different production dates, etc.).
c. Parts tested must be from actual production lots and are not to be built just for testing.
d. Manufacturers are not required to do periodic control testing if there has been no production
during the period covered by the testing.

1/ If there are no reported failures after two consecutive 26
week intervals then periodic testing can be done at 24
months intervals. If there are no reported failures after
the next 24 month interval, then periodic testing can be
done at 36 month intervals.
4.5.4.1 Nonconformance. If a sample fails to pass any periodic control test, the manufacturer shall
immediately notify the qualifying activity and cognizant inspection activity of such failure and take
corrective action on the materials or processes, or both, as warranted, and on all units of product which
can be corrected and which were manufactured under essentially the same conditions, with essentially
the same materials and processes, and which are considered subject to the same failure. The following
details shall apply:
a. Acceptance and shipment of the product shall be discontinued until corrective action,
acceptable to the qualifying activity has been taken.
b. After the corrective action has been taken, periodic control tests shall be repeated on
additional samples (all inspections, or the inspection which the original sample failed, at the
option of the qualifying activity).
