GB/T 14365-2017 Translated English of Chinese Standard. (GBT 14365-2017, GB/T14365-2017, GBT14365-2017): Acoustics - Measurements of Sound Pressure Level Emitted by Stationary Road Vehicles

Front Cover, Sep 14, 2018 - Technology & Engineering - 24 pages
This Standard specifies a test method, required environment and instrumentation for measuring the exterior sound pressure levels from road vehicles under stationary conditions, providing a continuous measure of the sound pressure level over a range of engine speeds. This Standard applies only to road vehicles of categories L, M and N equipped with internal combustion engines. This Standard provides a simple and easy measurement method that can measure the sound pressure level of reproducibility noise under the running conditions of the vehicle. The absence of combustion operation when the vehicle is stationary is outside the scope of this Standard.
