4.5.1.1 Examination of product. Each test set shall be examined carefully

to determine that the material and workmanship requirements have been met.

4.5.1.2 Operational test. Each test set shall be operated not less than

10 minutes to permit the temperature to stabilize and to check sufficient

characteristics and record adequate data to assure required test set operation.

4.5.1.3 Environmental burn-in.

Each test set shall be operated under the

conditions specified herein for a period of 48 operational hours without

failure. A failure shall be specified as anything which causes

malfunctioning of the test set. Only those adjustments will be permitted

which can be made using controls that are accessible to the operator during

normal use of the test set. The test time shall be comprised of nine 8-hour

environmental test cycles consisting of three hours (test set non-

operational) at -40C and five hours (test set operational) at +55C. The unit

shall be energized during the -40C performance test just prior to

transition from cold to hot, the transition from cold to hot, and the entire

hot soak. The performance tests shall be conducted once daily after

stabilization at each temperature. The test set shall be checked for

compliance with performance requirements. Should repetitive failures occur,

corrective action shall be taken to eliminate this defect from future test

sets. A record shall be kept of all failures.

4.5.2 Sample tests. Test sets selected for sample tests shall first have

passed the individual tests. Test sets will be selected for sample tests by
