| Abstract: |
| The work aims to explore the relationship between the accelerated sunlight simulation test with metal halide lamps for automotive parts and outdoor exposure. Three typical polymer transparent materials were used for a sunlight simulation acceleration test, an AIM BOX/Arizona outdoor exposure test, and a Florida outdoor exposure test. Based on the yellow values of the specimens after the test, the correlation between the sunlight simulation test and outdoor exposure was compared. And the acceleration of sunlight simulation tests and outdoor exposure was explored. The sunlight simulation (IP/DP box) acceleration test was highly correlated with the outdoor exposure of AIM BOX/Arizona. Its comprehensive acceleration rate was approximately 3 times that of AIM BOX/Arizona outdoor exposure. The sunlight simulation (outside IP/DP box) acceleration test is highly correlated with the outdoor exposure of Florid. Its comprehensive acceleration rate was approximately 7 times that of Florida outdoor exposure. Based on the study of three typical materials, it can be concluded that there is a certain correlation between the sunlight simulation acceleration test of automotive parts and typical outdoor exposure. |
