1. Purpose

This Requirements document establishes all design requirements that the design of the customized two-piece container must meet. Refer to this requirements document in conjunction with the ICD and SOW.

2. Definitions Container The pieces that enclose the material stored inside. Excludes any accessories, including handles, latches, or any other peripherals.

Container assembly The complete assembly that includes the container and all accessories and peripherals.

Corrugation Alternating protruding and recessed sections of the containers faces. Regarded as a feature and must abide by specified maximum external dimensions.

Two-piece construction The container consists of two pieces that can be separated to access the material stored inside, as well as a panel on both the front and rear faces. The two pieces will be referred to as the bottom and top pieces.

Split Line Refers to the dividing line between what would be considered the upper and lower halves of the container.

Latch Any device used to secure the two parts of the container together.

Maximum rated payload The maximum weight of material that the container assembly can transport while meeting all other requirements. Defined as 195 lb of payload suspended from six internal mounting points using elastomeric shock isolators and 50 lb of payload rigidly mounted to various internal and external regions of the container assembly.

Ready-to-lift configuration The container assembly is arranged as it would be for lifting by hand by four operators. All pieces are assembled and securely latched, the handles arranged to facilitate lifting by hand, and the container assembly is fully loaded to its maximum rated payload.

Transportation configuration

The container assembly is arranged as it would be for transportation. All pieces are assembled and securely latched, the handles stowed (if possible) to minimize the external dimensions of the assembly, and fully loaded to its maximum rated payload.
