4.6 Test methods and procedures.
4.6.1 Environmental.
4.6.1.1 Temperature test. - The panoramic telescope shall be sub-
jected 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 conform to the limits outlined in 3.3.1 and 3.3.2
using test procedures outlined 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 fixture 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 panor-
amic 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 above, however, the pressure and time values specified in
3.4.2 shall apply.
