The interior of the body shall have a smooth, cleanable finish and shall be free of pockets and restrictions that might collect refuse. The body shall load and retain all refuse material, including ashes and liquid-saturated garbage, without spillage or liquid leakage during both the refuse collection and the transport operations.

3.5.2 Capacities. The refuse body shall have a capacity of not less than that specified in table IV. The hopper shall have a capacity of not less than that specified in table IV, as computed in accordance with Truck Body and Equipment Association (TBEA) standards.

3.5.3 Hopper. For class A and B vehicles, the rear loading edge of the hopper shall be not more than 38 inches from the ground when the vehicle is without payload. For classes C, D and E, the loading edge shall be not more than 40 inches from the ground. The hopper shall be of watertight construction to prevent leakage. The dimensions of the hopper shall enable two men to empty the contents of two standard 55-gallon drums simultaneously into the hopper.

3.5.4 Compacting. The compacting devices shall clear the hopper by pushing or lifting its contents into the main cavity of the body. The operation of compaction devices shall not bypass refuse and shall ensure packing of refuse in the complete body volume. The movement of the compacting device shall be by hydraulic means capable of supplying a compacting pressure sufficient to produce the compaction density specified in table IV.

3.5.4.1 Compaction density. The compaction system shall be capable of compacting refuse to the density specified in table IV for each class of vehicle. This compaction density shall be considered normal service, such that in frequent compaction to this density, the stress levels required for long fatigue life of the vehicle are not exceeded.
