Product Code:SAE J2889/1
Title:Measurement of Minimum Noise Emitted by Road Vehicles
Issuing Committee:Safety And Human Factors Steering Committee
Scope: This SAE Standard is derived from SAE J2805 and specifies an engineering method for measuring the minimum noise emitted by road vehicles. The specifications reproduce the level of noise which is generated by the principal vehicle noise sources consistent with minimal noise emission in urban traffic. 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.The test method requires an acoustical environment which is only obtained in an extensive open space. Such conditions usually exist during:鈥? Measurements of vehicles for regulatory certification鈥? Measurements at the manufacturing stage鈥? Measurements at official testing stations
