13、the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13523-2:2001. The main technical changes are: a) the text was aligned with the revision of EN ISO 2813, i.e. the result of the measurement is expr
14、essed in gloss units (GU); b) the definition for specular gloss was deleted; c) for calibration of the glossmeter, a reference to EN ISO 2813 was added; d) a remark on preconditioning was added; e) the procedure was amended so that measurements can be taken in the rolling direction or perpendicular
15、to the rolling direction, which has to be stated in the test report; f) the selection of the measuring geometry was aligned with the revision of EN ISO 2813. g) for precision data, a reference to EN ISO 2813 was added.

BS EN 13523-2:2014EN 13523-2:2014 (E) 6 1 Scope This part of EN 13523 specifies the procedure for determining the gloss of an
23、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 of size greater than the aperture, thus, uneven surfaces cannot be measured. This method is applicable to all pigmented an
24、d unpigmented coatings including metallic/pearlescent coatings. However, for textured coatings it is only indicative. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only

27、s 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 gloss of the organic coating is determined by measuring the specular reflectance. The angle of incident light is usually 60,
28、 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 glossmeter or multi-angle glossmeter, in accordance with EN ISO 2813. 5.2 Calibration standards, as recommended by the manufac
29、turer of the glossmeter, in accordance with EN ISO 2813. 6 Sampling See EN 13523-0. BS EN 13523-2:2014EN 13523-2:2014 (E) 7 7 Test panels See EN 13523-0. 8 Procedure 8.1 Selection of the measuring geometry Specify the optimum reflector geometry based on a measurement of the sample with the 60 geomet
30、ry: 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 improved differentiation between high-gloss paint films, i.e. films with a 60 gloss higher than about 70 GU (gloss units). The 85 geo
31、metry 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 instrument with a high-gloss reference standard to the assigned gloss value, as specified in EN ISO 2813. 8.3 Measurement Meas
32、ure 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 (50 5) %, in accordance with EN 23270. Conditioning is carried out in accordance with EN 13523-0:2014, Clause 6. The gloss ma
33、y 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 aperture over the coated specimen and note the gloss reading. Take readings at not less than three different parts of the coated sp
34、ecimen 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 Express the result of the measurements in gloss units (GU), as the average of the readings taken. 10 Precision For precision data s
35、ee 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 this 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 rolli
36、ng direction or perpendicular to the rolling direction; BS EN 13523-2:2014EN 13523-2:2014 (E) 8 e) the results of the test, as indicated in Clause 9; f) any deviation from the test method specified; g) any unusual features (anomalies) observed during the test; h) the date of the test.
