This SAE Standard establishes the test procedure@ environment@ and instrumentation for determining the exterior sound level for passenger cars@ multipurpose vehicles@ and light trucks having a gross vehicle mass rating of 4540 kg or less. The test procedure is characterized by having fixed initial conditions@ i.e.@ an as-specified initial vehicle speed and gear selection at a fixed start point on the test site. Full-throttle acceleration and closed-throttle deceleration of the vehicle are included in this procedure. Sound levels determined in accordance with this document are dependent on the performance capability of the test vehicle@ as influenced by power-to-mass ratio and overall powertrain gear ratio.
