DIN EN 13523-2:2014-08 EN 13523-2:2014 (E) 5 Introduction In EN 1396 and EN 10169, tolerances against nominal gloss are given for different gloss ranges of the coil coated product. DIN EN 135
27、23-2:2014-08 EN 13523-2:2014 (E) 6 1 Scope This part of EN 13523 specifies the procedure for determining the gloss of an organic coating on a metallic substrate. Gloss is a characteristic of fundamental importance to the appearance of the coil coated product. The apparatus requires a flat specimen o
28、f size greater than the aperture, thus, uneven surfaces cannot be measured. This method is applicable to all pigmented and unpigmented coatings including metallic/pearlescent coatings. However, for textured coatings it is only indicative. 2 Normative references The following documents, in whole or i
29、n part, are normatively 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 meth

31、s For the purposes of this document, the terms and definitions given in EN 13523-0:2014 and the following apply. 3.1 gloss optical property of a surface, characterized by its ability to reflect light specularly SOURCE: FprEN ISO 4618:2014, 2.132, modified, Note 1 to entry deleted 4 Principle The glo
32、ss of the organic coating is determined by measuring the specular reflectance. The angle of incident light is usually 60, but angles of 20 or 85 may be used for more accurate measurement of high or low gloss values. 5 Apparatus Ordinary laboratory apparatus, together with the following: 5.1 60 gloss
33、meter or multi-angle glossmeter, in accordance with EN ISO 2813. 5.2 Calibration standards, as recommended by the manufacturer of the glossmeter, in accordance with EN ISO 2813. 6 Sampling See EN 13523-0. DIN EN 13523-2:2014-08 EN 13523-2:2014 (E) 7 7 Test panels See EN 13523-0. 8 Procedure 8.1 Sele
34、ction of the measuring geometry Specify the optimum reflector geometry based on a measurement of the sample with the 60 geometry: The 60 geometry is applicable to all paint films, but for very high gloss and near-matt films 20 or 85 might be more suitable. The 20 geometry is intended to give improve
35、d differentiation between high-gloss paint films, i.e. films with a 60 gloss higher than about 70 GU (gloss units). The 85 geometry is intended to give improved differentiation between low-gloss paint films, i.e. films with a 60 gloss lower than about 10 GU (gloss units). 8.2 Calibration Adjust the
36、instrument with a high-gloss reference standard to the assigned gloss value, as specified in EN ISO 2813. 8.3 Measurement Measure the gloss at ambient temperature. For more accurate measurements, as required for instance in case of dispute, the temperature shall be (23 2) C and the relative humidity
37、 (50 5) %, in accordance with EN 23270. Conditioning is carried out in accordance with EN 13523-0:2014, Clause 6. The gloss may be measured in the rolling direction or perpendicular to the rolling direction. The direction of measurement shall be stated in the test report. Place the instruments apert
38、ure over the coated specimen and note the gloss reading. Take readings at not less than three different parts of the coated specimen at the specified geometry (60, 20 or 85). Report the gloss as the average of these readings and report the geometry used if it is not 60. 9 Expression of results Expre
39、ss the result of the measurements in gloss units (GU), as the average of the readings taken. 10 Precision For precision data see EN ISO 2813. 11 Test report The test report shall contain at least the following information: a) all details necessary to identify the product tested; b) a reference to th
40、is part of EN 13523 (EN 13523-2); c) the geometry used if it is not 60; d) whether the measurement has been taken in the rolling direction or perpendicular to the rolling direction; DIN EN 13523-2:2014-08 EN 13523-2:2014 (E) 8 e) the results of the test, as indicated in Clause 9; f) any deviation fr
41、om the test method specified; g) any unusual features (anomalies) observed during the test; h) the date of the test.
