Based on this background, in 20 17, China Automobile Research Institute took the lead in publishing the framework of China automobile health index, and established a new standard of automobile health through a complete evaluation system. Under this standard, the organization will focus on the detection and quantitative evaluation of VOC, VOI, EMR, PM and VAR in the car, which is what we call the China Automobile Health Index.
