shall be performed in accordance with the applicable procedures specified
in MIL-STD-462 for Class IC equipment to determine compliance with 3.3.3.
4.6.4 Environmental requirements.
4.6.4.1 Operating conditions. - With laser trainer operating in
accordance with 3.5.5, there shall be no evidence of damage or deteriora-
tion and the trainer shall meet all the tests of 4.6.5 during the follow-
ing environmental conditions to determine compliance with 3.3.4.1.
4.6.4.1.1 Temperature. - The test apparatus shall be in accordance
with the applicable Test Facilities Provisions of MIL-F-13926, except that
assemblies may be mounted on the inside surface of the test chamber. Per-
form this test in accordance with temperature cycling, Procedure I of MIL-
F-13926, except with conditions of OF and 100F to determine compliance
with 3.3.4.1.1 and the sequence of testing is optional. Temperature
change shall not be greater than 3F per minute. Allow temperature to
stabilize for at least two hours. Then allow five minutes warm-up time
and fire three times before performing test of 4.6.5. This test may be
performed in conjunction with the test in 4.6.4.2.1.
4.6.4.1.2 Humidity. - This test shall be performed as specified in
MIL-STD-81O, Method 507.1, Procedure II, while operating laser trainer
to determine compliance with 3.3.4.1.2.
4.6.4.1.3 Altitude. - This test shall be performed as specified in
MIL-STD-81O, Method 500.1, Procedure I, except that the chamber pressure
will be limited to 10,000 feet to determine compliance with 3.3.4.1.3.
4.6.4.2 Non-operating conditions.- The laser trainer in the non-
operating, de-energized condition, shall show no evidence fo damage or
deterioration and shall be visually inspected for physical damage and
then tested to meet 4.6.5 after the following environmental exposure to
determine compliance with 3.3.4.2.
4.6.4.2.1 Storage temperature.- The test apparatus shall be in
accordance with the applicable test facilities provisions of MIL-F-13926
except that assemblies may be mounted on the inside surface of the test
chamber. To determine compliance with 3.3.4.2.1, conduct this test in
accordance with Temperature cycling, Procedure I of MIL-F-13926, with
conditions of -65F and +155F and the sequence of testing is optional.
Temperature change shall not be greater than 3F per minute.
4.6.4.2.2 Vibration "A". - To determine compliance with 3.3.4.2.2,
perform this test in accordance with Method 514.2 of MIL-STD-81O, pro-
cedure VIII, Curve V, Figure 514.2-6, with a vehicle mileage of 3000 miles.
