4.6 Test methods and procedures.
4.6.1 Environmental.
4.6.1.1 Temperature test. - The panoramic telescope shall be subjected
to test Procedure I of MIL-F-13926; however, the temperatures specified in
3.4.1 and 3.4.2 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 3.4.1 and 3.4.2 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
dipicted on Drawing F856556. 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 panoramic telescope, adjust
testing pressure to the pressure specified in 3.6.1 l nd maintain the
pressure for time specified in 3.6.1. Pressure gage shall remain constant
to assure compliance with 3.6.1. 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 unit.
4.6.1.2.1 Sealing (counter assembly). - This test to be accomplished
as outlined above, however, the pressure and time values specified in
3.6.2 shall apply.
4.7 Performance testing.
4.7.1 Orientation. - Proper orientation of the panoramic telescope
is assured when mounted and secured to an adapter, the accuracy of which
shall be equal to or better that the accuracy depicted on Drawing F8565945
and when aligned as outlined in set-up instuctions spectfied on Drawing
F8213899. With the panoramic telescope positioned on the fixture as out-
lined above the line of sight, elbow assembly, counters and the five mil
click mechanism shall be set as specified in 3.7.1.
4.7.2 Collimation.
4.7.2.1 Previbration. - With telescope positioned as outlined in
4.7.1, observe coincidence between the panoramic telescope line of sight
and the optical axis of the test reticle (target) in the collimator pro-
