Scope

Main technical content: This standard specifies the requirements for the quality of the flow field, testing equipment, and instruments in the aerodynamic wind tunnel test of complete vehicles. It recommends standard working conditions, testing methods, and processes for conducting aerodynamic tests, and provides evaluation methods for the validity of test data. The results obtained can be used as a basis for evaluating the aerodynamic performance of complete vehicles and optimizing their design. This standard applies to actual complete vehicles, namely passenger cars with seven seats or less and light pickup trucks, as well as vehicle models of corresponding sizes (clay models, hard models, etc.). The weight and size of the vehicles are determined based on the scale of the wind tunnel and the testing capabilities
