Accelerated weathering was performed according to ISO 4892-2(2013) Method A, Cycle 1 in a Q-SUN Xe-2 rotating rack xenon arc test chamber (Q-Lab Corporation, USA) equipped with a Xenon arc lamp emitting light equivalent to direct sunlight (Daylight-Q) using a silica glass filter. Rectangular specimens (100 x 10 x 2 mm 3 ) were fixed on specimen holders by clamping the ends. These holders were then mounted on the rotary rack and subjected to an irradiance of 60±2 W/m² in the range of 300 nm and 400 nm. The radiation exposure corresponded to an energy of about 213 MJ•m -2 .
