SAE AS5385D aims at identifying the design criteria and testing methods adequate to guarantee the ultimate load and operational dependability of cargo restraint strap assemblies with a typical 22250 N (5000 lbf) rated ultimate tension load capability, as used by the airline industry in order to restrain cargo on board civil transport aircraft during flight:

cargo loaded and tied down onto airworthiness certified air cargo pallets, themselves restrained into aircraft lower deck or main/upper deck cargo systems and meeting the requirements of NAS 3610 or AS36100, or
non-unitized individual pieces of cargo, or pieces of, cargo placed onto an unrestrained ("floating") pallet into either lower deck or main deck containerized cargo compartments of an aircraft.
