MIL-M-60170A(MU)
4.5.2.3.2.2 Line of sight test stand assembly.- The assembly shall
function as a holder for the mounting plate assembly with the periscope
mount in its normal operating position (see 3.4). Features shall be
designed into the line of sight test stand assembly that will assure
positive and accurate positioning and re-positioning (repeated removal
and replacement) of the mounting plate assembly on the test stand assembly
within 5 seconds in all planes.  An angle reading telescope, as shown in
Figure 1, shall also be part of the test stand assembly.  The angle read-
ing telescope shall have an entrance pupil of at least 2.0 inches, and
the capability of reading line of sight deviations in the "X" and "Y"
coordinates in seconds of arc.  The positioning of the telescope on the
test stand assembly shall be such that its optical axis is parallel within
5 seconds to Datum Plane "A" of the Mount Assembly 10513500 when the peri-
scope mount, assembled to the mounting plate, is positioned on the test
stand in accordance with 3.4.  The optical axis of the telescope shall
also be perpendicular to the mirror surface of the body assembly device
(see 4.5.2.3.2.3) within 5 seconds, when the body assembly device is
assembled to the periscope mount.
4.5.2.3.2.3 Body assembly device.- The body assembly device shall
have the required keys, datum planes, external dimensions, and weight
(45 pounds) of the Body Assembly Drawing F10542201. A mirror surface
finish shall be incorporated on the device for utilization in the line
of sight retention measurements of the mount by means of auto-collimation.
4.5.2.3.2.4 Vibration test stand assembly.- The vibration test
stand assembly shall function as a holder for the mounting plate assembly
with the mount (with body assembly device installed) maintained in its
normal operating position.  Features shall be designed into the vibration
test stand assembly that will assure positive and secure mounting of the
mounting plate assembly on the vibration test stand. The vibration test
stand shall be firmly and securely mounted on a vibration machine.
4.5.2.3.2.5 Vibrating machine.- The vibrating machine shall be
capable of providing the amplitude and frequency specified in 3.5.  The
vibrating machine shall also be capable of vibrating the mount along 3
mutually perpendicular axes while the mount is maintained in the posi-
tion specified in 3.4.
4.5.2.3.3 Insertion and removal, operability of controls and wiper
mechanism operation.- The special testing equipment for these tests shall
consist of a holding device, head assembly device, and a body assembly
device.  The holding device and head assembly device shall conform to
the requirements specified in 4.5.2.3.1, except that the head assembly
device utilized for the wiper mechanism tests shall contain an entrance
window conforming to the dimensional, and appropriate optical requirements
of C10513207.  The body assembly device shall conform to the requirements
specified in 4.5.2.3.2.3, except that the mirror surface finish is not
required.  A power supply for energizing the wiper motor shall be part
of the testing equipment.  The power supply shall be capable of supply-
ing and maintaining the voltages required in 3.8.2.1 through 3.8.2.3
