Operational test at certain environmental conditions. The conditions
may vary for each test set tested and should be based on results of
the first article, individual, and special tests.
Manufacturing run-in test specified in 188.8.131.52 except that the test
duration shall be 100 hours with no restriction on the number of
failures (see 6.2.2).
4.4.7 Reliability assurance tests. Reliability assurance tests shall be
conducted in accordance with the requirements of MIL-STD-781. Tests shall be
conducted as required for both the qualification phase and the production
acceptance (sampling) phase.
184.108.40.206 Reliability qualification phase. Prior to acceptance of test sets
under the contract or purchase order, a contractually specified quantity of
test sets (or a not less than three if not specified in 6.2.1) shall be
subjected to the combined reliability qualification requirements for
unsheltered shipboard equipment (category 3.B) of MIL-STD-781, using Test Plan
220.127.116.11 Reliability acceptance phase. Production lot samples of the test
sets shall be subjected to combined production reliability acceptance
requirements for unsheltered shipboard equipment (category 3.B) of MIL-STD-
781, using Test Plan VC therein
18.104.22.168.1 Acceptance phase sample size. The entire contract quantity (except
for those test sets used in the qualification phase) shall be considered one
lot. The reliability acceptance sample size shall be 10 percent of the
contract quantity, but not less than three units. The test program shall
start the first month after the qualification phase has been completed. The
samples shall be tested until an accept/reject decision has been reached. In
the meantime, other test sets manufactured may be shipped in place, if
acceptable to the procuring activity (see 6.2.2). The procuring activity
reserves the right to stop the acceptance of test sets anytime after one or
more reject decisions have been reached, pending a review of the contractor's
efforts to improve the test set, parts, and quality control in order that the
entire contract quantity will result in an accept decision.
22.214.171.124 Test details. The test details shall be part of the test procedures
