5.9.4 Tensile adhesion after water UV irradiation

Take a set of specimens prepared according to 5.1.2 and place them in a water ultraviolet irradiation test chamber. Immerse the specimens in deionized water with a resistance value of 1m-10m at a temperature of (45 ± 1) ℃. The upper part of the glass substrate should be level with the water surface and facing the light source. During the immersion treatment for 1008h, the specimen is exposed to a xenon arc lamp or equivalent light source that meets the requirements of GB/T16422.2. The irradiation intensity on the surface of the specimen is (60 ± 5) W/m2 in the wavelength range of 300nm-400nm, irradiated for 1008h. Remove the specimen and place it under standard test conditions for (24 ± 4) hours
