4.6 Test methods and procedures.
4.6.1 Environmental.
4.6.1.1 Temperautre test. - The panoramic Telescope shall be subjected
to test Procedure I of MIL-F-13926; however, the temperatures specified in
3.3.1 and 3.3.2 shall apply. When the panoramic telescope has been stabilized
at the temperature specified, the result of the specified test shall con-
form to the limits outlined in 3.3.1 and 3.3.2 using test procedures out-
lined herein.
4.6.1.2 Sealing optical assembly. - This test shall be performed
using testing equipment the accuracy of which shall conform to the accuracy
depicted on Drawing F8565556. When using pressure test fixture, the tixture
shall be set-up as outlined in set-up instructions shown on Drawing F8565556,
Sheet 1. The gas used shall be dry nitrogen having a dew point of -25F.
After connecting the test fixture to the panoramic telescope, adjust
testing pressure to the pressure specified in 3.4.1 and maintain the
pressure for time specified in 3.4.1. Pressure gage shall remain constant
to assure compliance with 3.4.1. At the completion of this test, connect
a dew point tester to the exit post and purge the optical assembly until
-25F is recorded and seal the instrument.
4.6.1.2.1 Sealing (counter assembly). - This test to be accomplished
as outlined aboved, however, the pressure and time values specified in 3.4.2
shall apply.
