This International Standard specifies a test procedure, environment and instrumentation for measuring theexterior sound pressure levels from road vehicles under stationary conditions, providing a continuous measureof the sound pressure level over a range of engine speeds. This International Standard applies only to roadvehicles of categories L, M and N equipped with internal combustion engines.The method is designed to meet the requirements of simplicity as far as they are consistent withreproducibility of results under the operating conditions of the vehicle.It is within the scope of this International Standard to measure the stationary A-weighted sound pressure levelduringtype approval measurements of vehicle;measurements at the manufacturing stage;measurements at official testing stations;measurements at roadside testing.This International Standard specifies neither a method to check the exhaust sound pressure level when theengine is operated at realistic loads nor a method to check the exhaust sound pressure levels against ageneral noise limit for categories of road vehicles.Technical background information is given in Annex A.
