A-A-52462 Containers, Shipping And Storage: Metal, Reusable; For Engines, Transmissions, Differentials, Transfers, And Similar Assemblies \(Metric\)This CID covers two types of leakproof, pressurized, metal, reusable containers/boxes \(hereinafter referred to as containers\). They are used as humidity controlled containers for shipment and storage of automotive engines, transmissions, differentials, transfers, and similar assemblies. The two types of containers are classified as follows \(see 5.2\): Type I - Pressurized container. Type II - Controlled breather container.

2.4.2.3 Tip over test. The packed container, erect on its base on a hard level floor, shall be

slowly tipped to the side until it falls freely and solely by its own weight to the floor. After

righting the container, the test shall be repeated on the opposite side. Cylindrical containers shall

be tipped at right angles to the longitudinal axis of the installed item and allowed to fall freely to

the floor.

2.4.2.4 Impact test. An impact test shall be applied to each end of the packed container. The

container shall be suspended, as a pendulum, at the end of four or more cables (two cables shall

be used for cylindrical containers with two lifting eyes). The cables shall be of sufficient length

to prevent any interference or binding. A flat, vertical, stationary masonry or metal barrier, with

a thickness of not more than 5 cm of wood between the barrier and container, shall be provided

for the container to strike against. The suspended container shall be raised vertically to a height

which will allow the lowest point of the container (while swinging through the arc of the

pendulum) to clear the floor. While the suspended container is resting lightly against the barrier

and prior to pulling back for the impact, the center of balance shall be marked (if not stenciled on

the container) as a measuring reference point. This mark shall be placed at the lowest point on

the container shell. The suspended container shall be pulled back with a straight even pull until

a height of 46 cm plus the aforementioned floor clearance is reached. This measurement shall be

taken from the measuring reference point on the container to the floor. At this point, the

container shall be released in a manner to allow a smooth even travel to the barrier.

2.4.2.5 Flatwise drop test. The packed container shall be raised so that its base is parallel to the

floor and allowed to fall freely once from a height of 15 cm and once from a height of 30 cm to a

concrete or metal surface.

2.4.2.6 Examination and functional test. Containers tested as specified in Rough handling shall

be opened and the contents examined for visible signs of movement and damage. When

specified (see 5.2), a functional test shall be conducted on the contents if the contents are a "live

load".

2.4.2.7 Finish treatment. Unless otherwise specified (see 5.2), cleaning, pretreating, priming,

painting, and exterior paint topcoat color of the containers shall conform to an appropriate

CARC paint system selected from Drawing No. 12369000.

2.4.2.8 Identification and marking. Unless otherwise specified in the AED, identification and

markings shall be permanent and legible and shall include, as a minimum, the AED container

part number and national stock number (NSN), the manufacturer's CAGE code and part number,

contract number, lifting points, and centers of gravity (see 5.2).
