Measurement of Exterior Sound Levels for Heavy Trucks Under Stationary Conditions(STABILIZED Apr 2021)
J1096_202104
This SAE Recommended Practice establishes the test procedure, environment, and instrumentation for determining the maximum exterior sound level of highway motor trucks and truck tractors over 4540 kg gross vehicle weight rating (GVWR) with governed engines under stationary vehicle conditions. The basic procedure involves a full throttle engine acceleration and a closed throttle deceleration with the engine inertia as the load.
Rationale:
The technical committee determines that the using community is moving towards newer technology and would like to alert users that this newer technology exists which may want to be considered for new design. However, because the technical committee has no complete visibility of where and how a technical report is being used, and because a technical report may be necessary to support legacy platforms or design reuse, the technical report should not be cancelled but rather stabilized with a rationale statement that alerts users to new technology.
