According to related Standards for Solar Radiation Tests,such as MIL-STD-810D/E505 of USA,DEFSTAN 00353-03 of Europe and GJB150.7A-2009of China,the experimental scheme is designed as follows:all of the discal and filmy samples were divided into 4 groups,one group was as-obtained PTFE,the other three groups were radiated by simulated sunlight for 4,8 and 12 days,respectively.The test equipment is Q-SUN XE-3-HSC type Solar Radiation Simulator,its schematic diagram is shown in Fig.1.The radiation source is made up of 3 parallelfixed Xe lamps,their energy and spectrum distribution are shown in Table 1.The test parameters were as follows,radiation intensity was 1 120 W/m2,test temperature was 55℃and the humidity was 70%RH,respectively.
