What is ISO 362-3- Measurement of noise- Indoor testing M and N categories about?

ISO 362-3 is a safety standard on the measurement of noise emitted by accelerating road vehicles . ISO 362-3 specifies an engineering method for measuring the noise emitted by road vehicles   of categories M and N by using a semi-anechoic chamber. The specifications are intended to achieve an acoustical correlation between testing the exterior noise of road vehicles in a semi-anechoic chamber and outdoor testing as described in ISO 362-1 . ISO 362-3 provides all necessary specifications and procedures for indoor testing to obtain   results which are comparable to typical run-to-run variations of measurements in today’s type   approval tests. ISO 362-3 provides a method designed to meet the requirements of simplicity as far as they are consistent with the reproducibility of results u...
