4. VERIFICATION
4.1 Test equipment and inspection facilities. Test and measuring equipment and inspection facilities of
sufficient accuracy, quality, and quantity to permit performance of the required inspection shall be
established and maintained by the contractor.
4.2 Classification of inspections. The inspection requirements specified herein are classified as follows:
a. Qualification inspection (see 4.4).
b. Quality conformance inspection (see 4.5).
4.3 Inspection conditions. Unless otherwise specified herein, all inspections shall be performed in
accordance with the test conditions specified in the "GENERAL REQUIREMENTS" of MIL-STD-202.
4.3.1 Mating jacks. Mating jacks used for inspections of plugs shall have been listed on, or approved for
listing on, the applicable qualified products list.
4.4 Qualification inspection. Qualification inspection shall be performed at a laboratory acceptable to the
Government (see 6.4) on sample units produced with equipment and procedures normally used in
production.
4.4.1 Sample size. Twelve plugs of each type shall be subjected to qualification inspection.
4.4.2 Inspection routine. The sample shall be subjected to the inspections specified in table I, in the order
shown. All sample units shall be subjected to the inspections of group I. The sample shall then be divided
equally into two groups of six units each and subjected to the inspection for their particular group.
4.4.3 Failures. One or more failures shall be cause for refusal to grant qualification approval.
4.4.4 Retention of qualification. To retain qualification, the contractor shall forward a report to the
qualifying activity at the end of 24 months. The qualifying activity shall establish the initial reporting date.
Subsequent reporting periods will be 36 months each. The report shall consist of:
a. A summary of the results of the tests performed for inspection of product for delivery, groups A
and B, indicating as a minimum the number of lots that have passed and the number that have
failed. The results of tests of all reworked lots shall be identified and accounted for.
b. A summary of the results of tests performed for verification of qualification inspection, group C,
including the number and mode of failures. The summary shall include results of all verification
of qualification inspection tests performed and completed during the 24- or 36-month period. If
the summary of the test results indicates nonconformance with specification requirements, and
corrective action acceptable to the qualifying activity has not been taken, action may be taken
to remove the failing product from the qualified products list.
Failure to submit the report within 30 days after the end of each 24- or 36-month period may result in loss
of qualification for the product. In addition to the periodic submission of inspection data, the contractor
shall immediately notify the qualifying activity at any time during the 24- or 36-month period that the
inspection data indicates failure of the qualified product to meet the requirements of this specification.
