UV exposure test was conducted according to JIS K 7350-2-1995 (Plastics - Methods of exposure to laboratory light sources Part 2:Xenon-arc source) on a Xenon Weather-Ometer Ci4000, Atlas Material Testing Technology LLC. Then the change of the optical and physical characteristic between before and after test was measured. Test condition was as follows.
Irradiance integral : 50W/m2 (300～400 nm)
BST temperature : 65±3℃
Relative humidity : 50±5％
Inner filter: Type S borosilicate
Outer filter: Soda lime glass
Water spray: none
Irradiation time: 100h, 200h

For your information, 100 and 200 hours irradiation is roughly estimated to be 10 years and 20 years indoor use, respectively.

The samples were tested under following temperature cycle.
‐30℃/30 min.⇔ 80℃/30 min.× 100 cycles (temperature up for 1 hour and down for 2 hours)
