LLRC DESIGN PROPOSAL FORMAT

Develop Long Life Reusable Containers (LLRC) for the _____

1.0 PURPOSE

The ___ Assembly (part number ____) requires the development, validation, and documentation of a new reusable shipping and storage container due to its unique dimensions and Government requirements described within this document. Upon completion of the efforts described within this document, the new reusable shipment and storage container will be implemented for the spare and repair part packaging, handling, storage, and transportability requirements of the ___ Assembly. The container will be designed to accommodate the ___ Assembly only. The Government requirements of the container are contained in SAE ARP 1967B with the exceptions listed in Appendix A of this document.

2.0 REUSABLE CONTAINER DEVELOPMENT

The LLRC vendor shall provide a reusable container for the ___ Assembly (part number ___) in accordance with SAE ARP 1967B. Exceptions from this practice are noted in Appendix A. The effort includes cost for development, design prototype construction, validation, and completion of the technical data package for competitive procurement.

This container shall only be fabricated from steel or composite material and must be Chemical Agent Resistant Coatings (CARC) finished as defined in SAE ARP 1967B. The use of wood in the design and fabrication of this reusable container is forbidden except for the container skids. This container should, as required, incorporate energy absorbing systems, dehumidification systems, and other special features to ensure protection of the item. This container should be capable of being repaired and/or retrofitted to prolong container service life or modified to adapt reusable container for shipment of the items other than for which it was originally intended. TB 9-289, Technical Bulletin for the Reconditioning of Type I and Type II Reusable Metal Containers, shall be used as a guide.

The container size shall be of the minimum, consistent with the size of the contents and the performance requirements of SAE ARP 1967B. During the life of the container, it will experience multi-model transportation (truck, rail, air, and ocean) so size considerations shall include all modes of transportation.

Edgewise Drop Test: The loaded container shall be supported at one end of its base on a wood sill nominally six inches high, placed perpendicular to the skids. The opposite end of the container shall be raised and allowed to fall freely from heights of 6, 12, 18, 24, 30 and 36 inches successively to a concrete or similarly hard surface. Two drops shall be made from the 36 inch height. This test shall be applied to the other end of the container.

Two drops shall be made from the 36 inch height. If the size of the container and the center of gravity are such that drop tests cannot be performed from all of the prescribed heights, the greatest attainable height shall be repeated for a total of six drops. This test shall be applied to diagonally opposite corners on each end of the container. If during the testing, the blocks shift more than six inches from the end of the skids, the blocks shall be repositioned at the ends of the skids.

4.5.3.3- N/A. This paragraph is not applicable to this requirement.

4.5.3.4 - Replace paragraph with the following:

Flatwise Drop Test: The container shall be raised in its normal storage position and allowed to fall freely from heights of 6 and 12 inches to land flat on a concrete or similarly hard surface. Container, 5 cubic feet to 25 cubic feet exterior volume, shall be dropped four times at each height. Containers 25 to 50 cubic feet shall be dropped twice from each height. Containers over 50 cubic feet shall be dropped once from each height.

4.5.4- Replace paragraph with the following:

Tipover Test: One of the following tests, whichever is applicable, shall be applied.

Roll-Over Test: This test applies to containers having a gross weight under 1,500 lbs. The container in normal storage position shall be rolled slowly sideways until it falls freely onto its side on a concrete or similarly hard surface. This procedure shall be repeated with a fall from one side to the top, from the top to the other side, and from the other side to the base. This test shall be applied to vertical cylindrical containers. In vertical cylindrical containers the component is mounted from one end with its longitudinal axis perpendicular to the base of the container.

Tip-Over Test: This test applies to containers having a width less than ¼ of the height and large containers with a gross weight over 1,500 lbs. The container in normal storage position on a hard level surface shall be slowly tipped to the one side until it falls freely to the ground. The container shall then be slowly tipped until it is back in the normal storage position. This test shall then be repeated to the other side of the container.

4.5.5 – N/A. This paragraph is not applicable to this requirement.

4.5.6 – Replace paragraph with the following:

Pendulum Impact Test: The container shall be suspended as a pendulum from four chains or cables (two chains or cables shall be used for cylindrical containers with two hoisting devices). The chains or cables shall be of sufficient length to provide a minimum distance of 16 feet from bottom of the container to point of suspension. The impact bumper shall be stationary and vertically flat and may be faced with a minimum nominal two inch thickness hardwood impact surface. The bumper impact surface shall be at least six inches high. The suspended container shall clear the floor or ground surface by two or three inches while swinging. The ends of the skids shall be the point of impact. The suspended container shall be pulled back perpendicularly from the bumper until a height of 18 inches or more than the floor clearance is reached. This measurement shall be taken vertically between a measuring reference point on the container and the floor or ground. The container shall be released to swing freely in a perpendicular line to strike the bumper. One impact shall be made on each end of the container.

4.5.7.1- Replace paragraph with the following:

Superimposed Load Resistance: One of the following tests, whichever is the greater load, shall be applied.

Concentrated Load Resistance: A simulated load equal to twice the weight of the container with its designated contents shall be stacked on top of the container. If the stacked height of three containers does not equal 16 feet, add additional weight until it stimulates containers stacked to a minimum height of 16 feet. Containers shall not be pressurized during this test. Measurements shall be taken to determine if permanent deformation has taken place.

Distributed Load Resistance: A load of 175 pounds per square feet shall be evenly distributed on the top surface of the container. This test shall not be applied to areas with curved or dome shaped cross-section. Containers shall not be pressurized during this test. Measurements shall be taken to determine if permanent deformation has taken place.

4.5.8.1 – Replace paragraph with the following:

Hoisting Test: The loaded container shall be suspended for at least two minutes clear of the ground (or other supports) by one of the hoisting provisions. The hoisting provision shall be capable of withstanding this test without failure or visible permanent deformation. This test shall be applied separately to each individual hoisting eye, ring, lug or bracket. Stationary hoisting devices shall not be positioned to extend beyond the maximum dimensions of the container. The same requirement applies to retractable hoisting devices when not in use.

4.5.8.3.2. – N/A. This paragraph is not applicable to this requirement.
