MIL-DTL-27443F (USAF)

4.5.7 Ultimate load. When uniformly loaded to rated capacity (see 6.3.1), the load being restrained to

the pallet by nets (see 6.3.4), the pallet installed between restraining rails locked to the rails by 2 locks

through each rail and engaging 2 lock notches on each side of the pallet, and resting on 4 rows of

conveyor as specified (see 3.4.5.1), the loaded pallet shall withstand a dynamic load of 3 times the

force of gravity (Gs) for a period of 0.1 second. The pallet shall be serviceable after undergoing the

test. In addition, the pallet shall withstand a dynamic load of 8Gs for a period of time not less than 0.1

second. The pallet need not be serviceable after undergoing such a load; however, the pallet shall

remain in one piece (see 3.4.6).

4.5.8 Environmental tests. The pallet shall be subjected to the following environmental tests in the

order shown:

4.5.8.1 High temperature test. The pallet shall be subjected to high temperature in accordance with

procedure I guidelines, method 501.4 of MIL-STD-810. After a 24-hour soak period at 125oF, the

pallet shall be loaded with a flexible, uniformly distributed load (see 6.3.1) and subject to 50

consecutive cycles of loading as follows without permanent deformation. One cycle shall have a

maximum duration of 30 seconds (see 3.4.7).

a. Lift the pallet completely off the floor by four tie down rings located adjacent to the corners on

the 88-inch sides.

b. Lower the pallet to rest on three 4x4x88 inch long supports equally spaced and aligned with the

short centerline. The lifting device shall be completely free of weight support while the pallet is at

rest on the supports.

4.5.8.2 Core resistance and low temperature test. Five 3/8-inch diameter holes shall be drilled through

the sandwich construction. One hole shall be in the center of the pallet and two each on the transverse

and longitudinal centerline 25 inches from the pallet edge. The pallet shall then be subjected to the

following immersions in the sequence listed (see 3.4.7):

a. Immerse 3 hours in water at room temperature; the upper surface of the pallet shall be covered

by at least 2 feet of water.

b. Remove from water and soak in a cold chamber for 4 hours at -65oF.

c. Stabilize at room temperature.

d. Repeat steps a and b.

e. While the temperature remains at -65oF, the pallet shall be subjected to 20 cycles of the same lift

test specified (see 4.5.8.1).

4.5.8.3 Humidity test. The pallet shall be subjected to humidity in accordance with Procedure III

guidelines, Method 507.4 of MIL-STD-810 (see 3.4.7).
