of 1,200 pounds minimum and the lid latched in place, an up-

ward pull of 300 pounds minimum shall be exerted on either

bar (see 3.4.3) selected at random. During and after the

test, the bar, the chest and the lid shall be inspected for

evidence of permanent deformation or failure, and the latches

shall be observed for malfunction. After this test, lid

operation shall be tested as specified for acceptance testing

in 4.6.2.

4.6.4 Drop. The chest, loaded with sand or other ap-

proved ballast to an evenly distributed gross weight of 1,200

pounds minimum, and with the lid latched in place, shall be

suspended by the lifting hooks, with the bottom surface of

the skids a minimum of 2 feet above a concrete floor or

equivalent. The chest shall be released by means of a suit-

able triggering device and shall fall free to the concrete

surface. After the test the lifting hooks, the chest, and

the lids shall be inspected for evidence of permanent de-

formation or failure and the latches shall be examined for

malfunction. After this test, lid operation shall be tested

as specified for acceptance testing in 4.6.2 and the chest

shall be subjected to the lifting tests specified in 4.6.3

feet above the concrete surface. One end of the chest shall

be supported on a bulkhead and the free end allowed to fall

to the concrete surface. After this test, the chest and lid

shall be examined for evidence of permanent deformation or

failure, and the latches shall be examined for malfunction.

Lid operation shall then be tested as specified in 4.6.2 for

acceptance testing.

fied in 4.6.4, it shall be towed from either end (selected
