MIL-PRF-11021H
4.5.2.2 Classification of defects. For examination purposes, defects shall be classified as
listed in TABLE VII.
4.5.3 Quality conformance test.
4.5.3.1 Acceptance test.
4.5.3.1.1 Sampling for acceptance tests. Sampling for acceptance tests shall be in
accordance with inspection level S-3 of ASQ Z1.4
4.5.3.1.2 Acceptance testing. Switch samples selected in accordance with 4.4.3.1.1 shall
be subjected to the tests specified in TABLE VIII, in accordance with inspection level S-3 of
ASQ Z1.4, using an AQL of 6.5 based on percent defective and in the sequence specified in
TABLE VIII.
4.5.3.2 Control tests. Control tests shall be conducted on three switch assemblies from
each lot of 500 units produced, except that not more than six nor less than three units shall be
tested in any 30 day period. Samples selected shall be examined for the defects specified in
4.4.2.2. The three samples selected shall be identified with the numbers 1, 2, and 3 and shall be
tested in the sequence specified in TABLE VI.
4.5.3.3 Crimp termination. Control test samples of each crimp termination,
representative with regards to the terminal barrel size and gauge of attached wire, shall be
periodically selected at the rate of 5 of each 500 crimp terminations produced. Not more than 50
or less than 15 crimp terminations shall be selected in any 30-day period. Samples selected shall
be examined for the defects specified in 4.4.3.2 and shall be tested in the sequence specified in
TABLE VI.
4.5.4 Failure. Failure of any switch assembly or crimp termination sample to pass any of
the specified inspections shall be cause for the Government to refuse acceptance of the
production quantity represented, until action taken by the contractor to correct defects and
prevent recurrence has been approved by the Government.
4.6 Performance test.
4.6.1 Electrical continuity test. To determine conformance to 3.4.1, the electrical
continuity shall be measured at each of the specified switch positions between pin F or pin K, as
required, and the remaining pins to complete the specified circuits on Figure A1.
4.6.2 Voltage drop test. To determine conformance to 3.4.2, the voltage drop shall be
measured at a minimum current of 10 amperes (0.40 ampere for the panel dim circuit) across the
circuits as specified in 4.6.1.
4.6.3 Circuit breaker continuous current capacity and ultimate trip current test. To
determine conformance to 3.4.3, each switch assembly shall be conditioned at each of the
ambient temperatures specified in TABLE III for a minimum of 5 hours. After conditioning, and
