Outline
In this paper, the applicability of DIN 75220 Aging Automobile Components in Solar Simulation Units to the typical dry, humid and hot climate environment in China was studied by comparing and analyzing the light, temperature and humidity conditions and vehicle test results in the environmental chamber and atmospheric exposure tests. The results show that the nighttime temperature of the simulated dry hot climate environmental cycle conditions in DIN 75220 standard is higher than the winter nighttime low temperature of domestic dry hot climate environment, and the nighttime temperature and humidity in the simulated humid hot climate environmental cycle test conditions is lower than the nighttime temperature and humidity in the domestic humid hot climate environment. The cycle test of DIN 75220 for 600 h is equivalent to 6~7 months of dry hot atmospheric exposure test and equivalent to 8~9 months of humid & hot atmospheric exposure test, which can reflect about 69% of the test problems occurred in 6~9 months of atmospheric exposure test.
