4.4.1 Environmental test. A sample case set, properly closed, shall be subjected to each of the
following tests in accordance with the applicable procedures of MIL-STD-810. To expedite testing, additional
cases may be submitted for environmental testing at the option of the manufacturer.
4.4.1.1 The following tests shall be conducted with the case set drawers inserted in their respective
case prior to testing.
4.4.1.1.1 Low temperature. One case set shall be subjected to a low temperature test in accordance
with MIL-STD-810, Method 502, Procedure I . At the end of the exposure period, the case set shall be
inspected to determine compliance with 3.6.
4.4.1.1.2 High temperature. One case set shall be subjected to a high temperature test in
accordance with MIL-STD-810, Method 501, Procedure I . At the conclusion of this test, the case set shall be
inspected to determine compliance with 3.6.
4.4.1.1.3 Humidity. One case set shall be subjected to a humidity test in accordance with MIL-STD-
8l0, Method 507, Procedure I for five cycles (120 hours). Each case shall be weighted prior to the test. At the
conclusion of the test, the exterior moisture shall be wiped dry and each case reweighed prior to opening.
The gain in weight of either case shall not exceed 5 percent of the initial weight of the respective cases. The
cases shall then be inspected to determine compliance with 3.6.
4.4.1.1.4 Salt spray. One case set shall be subjected to a salt spray test in accordance with MIL-
STD-810, Method 509 for 100 hours. The case set shall then be inspected to determine compliance with 3.6.
4.4.2 Drop test. Sample case sets with the drawers removed, shall be subjected to the drop test.
The case sets shall be prepared for testing with 200 pounds of dummy load in each case. Each case shall be
subjected to one free fall on each of the eight corners from a height of 24 inches. The case shall be
positioned for the drop test with two diagonally opposite corners in a vertical line. The case shall fall to a rigid
concrete surface. The case after dropping will remain symmetrically rectangular and steady (See 3.6.4). The
case shall be inspected to determine compliance with 3.6.
4.4.3 Handle test. Following the test specified in 4.4.2, the sample case set with the drawers
removed shall be subjected to the handle test. The dummy load of 200 pounds shall be retained in each
case, and the cases lifted separately by each handle clear of the floor. The cases shall be lifted in this
manner five times by each handle and held for five minutes each time. The handles shall remain tightly
attached to the case and in good working condition (see 3.4.2). The case shall then be inspected to
