This standard specifies the test method for evaluating the surface wettability of aluminum foil after annealing, primarily used to assess its suitability for subsequent processing such as printing and coating. The standard elaborates on the "wiping method" and designates it as the arbitration method, while also including test methods based on the principle of surface tension. The core instrument for conducting wettability testing is a contact angle measuring device, which analyzes the contour of liquid droplets on the aluminum foil surface through optical imaging to precisely measure the contact angle and quantitatively evaluate wettability.
