Over deze norm
This International Standard specifies a test procedure, environment and instrumentation for measuring the exterior sound pressure levels from road vehicles under stationary condition, 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 an internal combustion engines. The method is designed to meet the requirements of simplicity as far as they are consistent with reproducibility of results under the operating conditions of the vehicle. It is within the scope of this standard to measure the stationary A-weighted sound pressure level during: - type approval measurements of vehicle; - measurements at the manufacturing stage; - measurements at official testing stations; - measurements at roadside testing.
