3-12. Depot Overhaul Standards

Performance Tests

Tests on repaired equipment are designed to

measure the performance capability of the equip-

ment. Equipment that is returned to stock should

meet the standards given in the tests.

NOTE

The depot overhaul standards (c be-

low) should not be used to test the per-

formance of new equipment; that is,

equipment that has not been repaired or

rebuilt. Such equipment should be tested

for conformance with the electrical and

operational tests cited in MIL-C-55126-

(EL) under which the equipment was

manufactured including any waivers

and/or changes to the specification

which were imposed upon or granted to

the particular manufacturer of the equip-

ment. For such information, address
