The scope of this SAE Recommended Practice covers specialized internal combustion engine powered equipment used in support of aircraft operations. The equipment may be self-propelled, truck mounted, trailer mounted, skid mounted or stationary. It does not include construction equipment or equipment designed primarily for operation on highways or within factories or building areas.

NOTE: Equivalent methodology is provided in (CEN) EN 1915-4, Aircraft ground support equipment - General requirements - Part 4: Noise measurement methods and reduction, to be used for measurements conforming to the EU Machinery Directive

Purpose

The purpose of this recommended practice is to establish test procedures, environment and instrumentation for determining the exterior sound level of specialized aircraft ground support equipment. The measured sound levels will be useful to equipment manufacturers and airline ground equipment engineers in development of equipment, comparison of equipment and determining sound level exposures of those working with the equipment.
