Abstract : The purpose of this test is to qualify one (1) Sequence Timer to Test Procedure RT 315261. The specimen was functionally tested, consisting of monitoring the time sequence of all programmed events and the circuits resistance of normally closed circuits. The unit was checked for gas leakage during the initial bench test, temperature-humidity test and altitude test. Following the initial functional tests, the specimen was subjected to vibration, shock, acceleration, temperature-humidity and altitude environments. The unit may be considered qualified as a result of these tests. (Author)
