Outline
To in vestigate the consistency of results from outdoor exposure and xenon lamp aging tests on exterior plastics, 8 kinds of materials are selected to compare their appearance, clolr difference, gloss and tensile strength, and correlation coefficient is used to analyze the correlation between the two tests. The research results show that results of xenon lamp aging and outdoor exposure vary for ditferent materials, among which 6 materials have more severe results after Hainan exposure than Dunhuang exposure. For PMMA+ASA, PC and PMMA, SAE J2527 cannot accurately simulate exposure results in Hainan region. Furthermore the changes of tensile strength after xenon arc exposure 4 000 kJ are the same as 2 years outdoor exposure.
