4.6.3.l.2 High intensity. Use item 2 of table 1X and subject the
rangefinder to the shock test specified in MIL-STD-810, method 516.2,
procedure IV, figure 516.2-2. Apply three half sine wave shock pulses in each
direction along the three axes. Peak amplitude shall be 100.0 10.0 g with a
time duration of 1.5 0.2 msec measured at the 10 percent amplitude points.
At the conclusion of this test, subject the rangefinder to the performance
tests of table VI.
4.6.3.2 Vibration.
4.6.3.2.1 Vibration A. Use item 2 of table IX and subject the
rangefinder to the vibration test specified in MIL-STD-810, method 514.2
procedure VIII, except that the test level shall be the vibration curve shown
in figures 1 and 2 and duration of exposure shall be not less than 80 minutes
per axis. At the conclusion of this test, subject the rangefinder to the
performance tests of table VI.
4.6.3.2.2 Vibration B. This test shall be conducted as in 4.6.3.2.1
except that the period of vibration shall be not less than 15 minutes in each
axis.
4.6.3.3 High temperature. Subject the rangefinder to the high
temperature test specified in MIL-STD-810, method 501.1, procedure I. The
highest operating temperature shall 125F. The performance tests of table
VI shall be applied.
4.6.3.4 Low temperature. Subject the rangefinder to the low temperature
test specified in MIL-STD-810, method 502.1, procedure 1. The storage
temperature shall be -65F. The lowest operating temperature shall be
-25F. The performance tests of table VI shall be applied.
4.6.3.5 Humidity: Place the rangefinder in a humidity chamber and
subject it to the humidity test specified in MIL-STD-810, method 507.1,
procedure IV. During steps 4, 6 and 8 of procedure IV, subject the
rangefinder to the performance tests of 4.6.2. After exposure, subject the
rangefinder to the performance tests of table VI.
4.6.3.6 Altitude. Place the rangefinder in an altitude chamber and
subject it to the altitude test specified in MIL-STD-810, method 500.1,
procedure I, except that:
a. First, the rangefinder in a non-operating condition, shall be
exposed to an atmospheric pressure equivalent to 40000 feet
above sea level for a period of not less than 1 hour.
b.
Second, with the chamber pressure increased to an atmospheric
equivalent to 10000 feet above sea level, subject the
rangefinder to the performance tests of table VI.
