38、 permit clamping of the body asseiiibly securely to the device when the catches reach their apex and are fully closed. While exposed to the temperature extremes specified in 3.3.3 the catches shall be manually operated to determine compliance with the requirements of 3.3.3. Upon completion of the sp
39、ecified tests and return to standard ambient tempera- ture, (60“ to 90“ F) the body assembly shall be inspected for evidence of physical damage such as casting failure or glass breakage. It shall then be subjected to the tests specified in 4.5.2.2 to 4.5.9 inclusive to determine conformance with the
40、 requirements referenced therein. 4.5.2.2 Rigidity. - This test shall be accomplished by means of a test fix- ture as shown in Figure 1. The fixture shall be clamped to a vibration table. Clamp the body assembly in the fixture by means of the catches and immobilize catches to prevent accidental open
41、ing during vibration. The body assembly shall be vibrated in a vertical plane at the amplitude and frequency specified in 3.3.2 for a period of 24 minutes 2 15 seconds. The vibration amplitude shall be measured at the extreme bottom portion of the body assembly as positioned in the fixture. During v
42、ibration, observe rigidity of the body assembly in the test fixture using a stroboscope to produce the optical effect of stopping the vibration motion to determine rigidity at the locating and mating surfaces. The body assembly shall remain secure against the test fixture receiving surfaces to insur
43、e compliance with the requirements of 3.3.2. Subsequent to vibration the body assembly shall be subjected to a visual and tractile examination and shall show no evidence of physical damage or failure, The body assembly shall then be subjected to the tests specified in 4.5.3 to 4.5.9 inclusive to det
44、ermine compliance with the requirements referenced therein. 4.5.3 Cleanliness. - Optical surfaces of the completed body assembly shall be inspected for cleanliness in accordance with MIL-0-13830 and shall meet the requirements specified in 3.4.

45、illimeter, when determining sizes of dirt particles. 4.5.4 Sealing. - Standard pressure testing equipment capable of measuring and monitoring the internal pressure of the body assembly shall be utilized for the sealing test, Pressurize the body assembly with dry nitrogen gas to the psig value specif
46、ied in 3.5 for a period of 5 minutes, During this time period the interior pressure shall not decrease in compliance with the requirement specified in 3.5. 4.5.5 Light deviation. - This test shall be performed utilizing an auxiliary telescope of at least 3 power, containing a horizontal and vertical
47、 reticle line, mounted on a supporting device capable of holding the telescope and body assembly in a position permitting an incident line of sight to be directed from a calibrated target in a collimator projector, through the body assembly to the auxiliary tele- scope. Utilize the space in between
48、the pads and the back surface of the 3/4 inch keyways to centrally position the body assembly in the device with the machined top surfaces of the pads on the same plane with the line of sight through the telescope. The target pattern shall consist of a horizontal and vertical cross line with limit m
49、arks 45 minutes from the intersection of the crossline. Limit marks shall also be added in each quadrant, offset 45 minutes of arc from the horizontal crossline, to subsequently measure image tilt.
