25、rt of EN 13523 specifies the procedure for determining the resistance to cracking and/or pick-off on rapid deformation of an organic coating on a metallic substrate in terms of energy which the specimen will withstand. 2 Normative references The following documents, in whole or in part, are normativ

26、ely referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 13523-0:2014, Coil coated metals Test methods Part 0: General

27、introduction EN 23270, Paints and varnishes and their raw materials Temperatures and humidities for conditioning and testing (ISO 3270) EN 60454-2, Pressure-sensitive adhesive tapes for electrical purposes Part 2: Methods of test (IEC 60454-2) EN ISO 6272-1, Paints and varnishes Rapid-deformation (i

28、mpact resistance) tests Part 1: Falling-weight test, large-area indenter (ISO 6272-1) 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 13523-0:2014 apply. 4 Principle The test specimen is deformed (indentation in the form of a dome), using a falling we

29、ight. Usually, the deformation is carried out from the reverse side but can occasionally be carried out directly on the coated surface under test. The resistance of the coating to cracking and/or pick off is then determined. 5 Apparatus and materials 5.1 Apparatus in accordance with EN ISO 6272-1, e

30、quipped with a hemispherical striker, of diameter 20 mm and having two scales, one of which corresponding to a mass of 1 000 g, the other to a mass of 2 000 g. 5.2 Magnifying glass 10. 5.3 Transparent pressure-sensitive adhesive tape, 25 mm wide, with an adhesion strength of (10 1) N per 25 mm width

31、 when tested in accordance with EN 60454-2. 6 Sampling See EN 13523-0. DIN EN 13523-5:2014-08EN 13523-5:2014 (E) 6 7 Test panels See EN 13523-0. 8 Procedure Measure the resistance to rapid deformation at ambient temperature. For more accurate measurements, as required for instance in case of dispute

32、, the temperature shall be (23 2) C and the relative humidity (50 5) % in accordance with EN 23270. Conditioning is carried out in accordance with EN 13523-0:2014, Clause 6. Place the test panel in the apparatus (5.1) with the coated surface to be tested facing downward (reverse impact test). The te

33、st may occasionally be carried out for forward impact. Drop the mass from the required height to provide the appropriate energy of impact. Assess the resistance to cracking with normal corrected vision and the 10 magnifying glass (5.2). If resistance to pick-off is to be evaluated, remove two comple

34、te laps from a reel of the adhesive tape (5.3) and discard. Remove an additional length at a steady rate and cut a piece, approximately 75 mm long. Place the centre of the tape over the deformation and smooth the tape into place over a distance of at least 20 mm either side with a finger. To ensure

35、good contact with the coating, rub the tape firmly with a fingertip. The colour of the coating seen through the tape is a useful indication of overall contact. Within 5 min of applying the tape, remove the tape by holding the free end and pulling it off steadily in 0,5 s to 1 s at an angle that is a

36、s close as possible to 60 to the panel. Resistance to pick-off is evaluated after removal of tape: no loss of adhesion is allowed. Retain the tape for reference purposes, for example by attaching it to a sheet of transparent film. 9 Expression of results Record the resistance to no cracking and/or n

37、o loss of adhesion in Joules. State whether resistance to cracking and/or loss of adhesion has been measured. 10 Precision No precision data are currently available. 11 Test report The test report shall contain at least the following information: a) all details necessary to identify the product test

38、ed; b) a reference to this part of EN 13523 (EN 13523-5); c) the results of the test, as indicated in Clause 9; DIN EN 13523-5:2014-08EN 13523-5:2014 (E) 7 d) any deviation from the test method specified; e) any unusual features (anomalies) observed during the test; f) the date of the test.
