Product Code:SAE J1175
Title:Bystander Sound Level Measurement Procedure for Small Engine Powered Equipment
Issuing Committee:Small Engine And Powered Equipment Committee
Scope: This SAE Recommended Practice establishes the instrumentation and procedure to be used in measuring the bystandard sound level of engine powered equipment under 15 kW (20 bhp) typical of their normal operation. It is intended to include equipment such as lawn mowers, snow blowers, and tillers. It is not intended to include equipment designed primarily for operation on highways or within factories and buildings, or vehicles such as motorcycles, snowmobiles, and pleasure motorboats that are covered by other SAE Standards or Recommended Practices. This procedure does not cover chain saws. The SAE Recommended Practice may also be used when measuring the bystander sound level on similar equipment powered by electricity or other power sources.
Rationale: This SAE Recommended Practice establishes the instrumentation and procedure to be used in measuring the bystandard sound level of engine powered equipment under 15 kW (20 bhp) typical of their normal operation.
