4.4 Conformance inspection. Conformance inspection shall be in accordance with MIL­PRF­19500 and as
follows.
a.
If the manufacturer chooses the following option(s) for testing, the sample units that are to be used in
group C inspection shall be designated as such, prior to conducting the referenced group B tests.
Moreover, the number of failed diodes to be counted for lot acceptance or rejected as a result of group C
test shall be equal to all failed diodes of the test in group B inspection, which were predesignated for use
in group C inspection, plus any additional failures occurring group C testing. For each life test in group C
inspection, the manufacturer has the option of using all, or a portion of, the sample already subjected to
340 hours of group B life testing for an additional 660 hours of testing to meet the 1,000 hour requirement.
b.
Panel mount assemblies shall be assembled with LEDs that have met the requirements of groups A, B, and
C, and the applicable screening requirements specified herein. The quality conformance inspection for
panel mount assemblies shall consist of the examinations and inspections specified in table II herein.
4.4.1 Group A inspection. Group A inspection shall be conducted in accordance with table E­V of
