This SAE Standard establishes the test procedure@ environment@ and instrumentation to be used for measuring the exhaust sound level of passenger cars@ multipurpose vehicles@ and light trucks under stationary conditions. Measurements are taken under steady-state conditions. This sound level measurement procedure has been developed as a guide for governmental agencies establishing in-service sound level limitations and enforcement measurement procedures. It is directed at the assessment of vehicle exhaust noise and is not intended to determine maximum vehicle sound levels.
