MIL-DTL-83522E
NOTES:
1/ An "X" indicates that this optical measurement applies for the inspection. See appropriate test paragraph for details.
2/ Group V tests are for parts intended for space flight. Group V tests will be performed by NASA.
3/ Perform the change in optical transmittance measurement both during and after the test (with the baseline measurement performed
before the test).
4/ Perform the change in optical transmittance measurement after the test (with the baseline measurement performed before the test).
5/ Perform temperature in lieu of temperature cycling when specified. The soak duration at the low and high temperature cycling tests
are performed at both low and high temperature limits for one cycle and 10 cycles, respectively.
6/ Either an additional four mated pair can be fabricated for this test of the Group 3 samples may be used after completion of Group 3
test.
7/ Polymeric parts from 1 mated pair.
8/ Two mated pair from Group 2.
9/ Initial qualification and re-qualification are performed on connectors with both single mode (SM) and multimode (MM) mated pair.
The number of mated pair listed in table is for one fiber type.
10/ Group 1 mated pair are to be used for Groups 2, 3 and 4.
11/ When performing initial qualification or re-qualification with both singe mode (SM) and for multimode (MM) and when specified, four
MM mated pairs may undergo Group 1 and shock testing only. Single mode mated pair shall undergo specified the cited
inspections/tests. This multimode reduction in tests required is applicable if the only differences, between SM and MM, are ferrule
diameter dimension, ferrule hole diameter dimension, boot color (optional) and markings.

4.7 Inspection methods.
4.7.1 Equivalent test methods. The use of equivalent test methods is allowed subject to the following conditions:
a. The allowance of an equivalent method is specified in this specification.
b. The manufacturer has conducted both test methods and has submitted complete test data to the preparing activity (PA).
c. The preparing activity has approved the use of that method by that manufacturer.
