23、13523-17:2012-02 EN 13523-17:2011 (E) 5 1 Scope This European Standard specifies two methods for determining 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 th
24、e strippable film has been applied in the laboratory or on the production line. NOTE Method 1 is preferred for films with adhesive and method 2 for films without adhesive. 2 Normative references The following referenced documents are indispensable for the application of this document.

25、rences, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

27、a temporary protection against mechanical damage NOTE Strippable film is also referred to as protection foil. 4 Principle The force necessary to peel a film of given width from the surface of a coil coated material, at a defined angle and speed, is determined using appropriate instruments. 5 Apparat
28、us 5.1 For method 1 5.1.1 Hydraulic or electronic dynamometer with: a movable jaw speed of (300 30) mm/min; a measuring scale usually reading from 0 N to 10 N; a traction meter set so that the force required to strip the film lies between 15 % and 85 % of the measuring scale.

30、preparation 8.1.1 Self-adhesive strippable film When self-adhesive strippable film is applied in the laboratory, observe the following requirements: a) Store the roll of film before use for a minimum of 24 h at ambient temperature and humidity. For more accurate measurements, as required for instanc
31、e in case of dispute, the temperature shall be (23 2) C and relative humidity (50 5) %, in accordance with EN 23270:1991. Apply the film under these conditions. b) Apply the film to the surface of the test samples immediately after it has been uncoiled from the roll; take every care to avoid folds a
32、nd 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 a pressure of 2,0 N/mm width to press down the film, the metal roller being made to travel twice
33、 in a longitudinal direction over and back across the film surface; speed of travel shall be as close as practicable to 10 mm/s; no additional pressure shall be exerted on the test panel surface. Measure adhesion values (10 1) min after the film has been applied. Measure the adhesion of the strippab
34、le film at ambient conditions. 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 23270:1991. 8.1.2 Non-adhesive strippable film When non-adhesive strippable film is applied in the labora
35、tory, heat the substrate before application to a temperature specified by the film supplier. After application of the strippable film, cool down the sample in a way as close as possible to the production line conditions. DIN EN 13523-17:2012-02 EN 13523-17:2011 (E) 7 8.2 Determination 8.2.1 Method 1
36、 Prepare five samples of dimensions 200 mm 60 mm. The 200 mm edge should be cut in the rolling direction (see 1 in Figure 1). Cut through the strippable film with a cutting tool approximately 10 mm from each long edge and along the full length of each panel. Remove the film along both edges leaving
37、approximately 40 mm of film along the centre of the samples. Make five reference marks on each long edge of the samples at intervals of 30 mm, the first 50 mm from one end (end c). The marks shall be 5 mm long, neither touching nor damaging the film (see Figure 1). Detach by hand not more than 25 mm
38、 of film from end c perpendicular to the surface of the sample. Clamp the bared end (c) of the sample in one jaw of the dynamometer. Fold the detached film back by 180 degrees and clamp in the other jaw so that the film surfaces are accurately aligned without touching. Start the dynamometer at a spe
39、ed of (300 30) mm/min ensuring that the removed film moves parallel to, and does not touch, the film remaining on the sample (no friction between film surfaces). As the point of contact between film and sample reaches a reference point, the force indicated on the dynamometer scale shall be recorded.
40、 The result for the sample shall be the mean of the five measurements. Carry out the test on all five samples.

41、 Prepare a sample of dimensions 150 mm 200 mm. The 150 mm edge should be cut in the rolling direction (see 1 in Figure 2). Cut through the strippable film with a cutting tool approximately 25 mm from and parallel to a short edge. Make five further cuts parallel to the first cut at 30 mm intervals. R
42、emove the film at both edges leaving five strips of 30 mm (see Figure 2). Detach by hand not more than 55 mm of one end of the first strip of film. Clamp the detached end of the film strip to the spring balance. Hold down the sample and peel off the film by raising the spring balance perpendicular t
43、o the sample surface at a constant speed so that a steady reading is obtained. Record the reading indicated on the spring balance. Repeat the test on the remaining strips.
