16、ermining the numerical evaluation of the adhesion of strippable films which have previously been applied to an organic coating on a metallic substrate. Samples can be tested irrespective of whether the strippable film has been applied in the laboratory or on the production line. NOTE Method 1 is pre

23、 of 24 h at ambient temperature and humidity. For more accurate measurements, as required for instance in case of dispute, the temperature shall be (23 2) C and relative humidity (50 5) %, in accordance with EN 23270. Apply the film under these conditions. b) Apply the film to the surface of the tes
24、t samples immediately after it has been uncoiled from the roll; take every care to avoid folds and blisters; press the film into place in the first instance by finger-tip pressure only. c) Use a cylindrical metal roller, rubber-covered to approximately 80 Shore, with a minimum diameter of 50 mm and
