What is ISO 5130 - Sound pressure level emitted by stationary road vehicles about?

ISO 5130 is an international standard on road vehicles measuring the sound pressure levels of exhaust systems of passenger cars and light trucks. ISO 5130 specifies a test procedure, 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. ISO 5130 applies only to road vehicles of categories L, M, and N equipped with internal combustion engines. ISO 5130 measures the stationary A-weighted sound pressure level during
