The purpose of this SAE Aerospace Standard (AS) is to standardize the basic design, performance, and testing requirements for "Cargo Stoppers" cargo tie-down accessories to be used in conjunction with approved restraint straps meeting AS5385C (TSO C-172) requirements.

The lack of an agreed industry standard resulted in uncertainties about their operational capabilities so that it was deemed advisable to specify the applicable design, minimum performance, and testing requirements, since Cargo Stoppers are used as part of cargo tie-down arrangements that must meet regulatory airworthiness requirements.
