15、3 1 Scope This part of EN 13523 describes the procedure for determining the resistance to abrasion and wear of an organic coating on a metallic substrate. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the
16、edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 13523-0:2001, Coil coated metals Test methods Part 0: General introduction and list of test methods. EN 23270, Paints and varnishes and their raw materials Temperatures
17、 and humidities for conditioning and testing (ISO 3270:1984). ISO 7784-2, Paints and varnishes Determination of resistance to abrasion Part 2: Rotating abrasive rubber wheel method. 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 13523-0:2001 apply. 4
18、 Principle A coated test panel is placed on a rotating disc under a set of two abrasive wheels mounted in parallel and symmetrically on opposite sides of the centre rotating in the reverse direction. 5 Apparatus 5.1 Taber abraser, as specified in ISO 7784-2, or equivalent equipment. 5.2 Analytical b
19、alance, accurate to 0,1 mg. 5.3 Suction device, with two nozzles. One of the nozzles shall be positioned between the two wheels and the other placed diametrically opposite the first. The distance between the axes of the two nozzles shall be (75 2) mm and the distance between them and the test panel
20、1 mm to 2 mm. When the suction nozzles are in position, the air pressure in the suction device shall be 1,5 kPa to 1,6 kPa lower than the atmospheric pressure. 6 Sampling See EN 13523-0. EN 13523-16:2004 (E) 4 7 Test panels See EN 13523-0. Cut three test panels to approximately 100 mm 100 mm with a
21、hole drilled in the centre, appropriate for the apparatus being used. The test panels shall be flat and free from any edge burr to avoid any deformation of the test panels. 8 Procedure 8.1 Test conditions Measure the resistance to abrasion of the organic coating at ambient conditions. For more accur
22、ate 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. 8.2 Determination First determine the mass of each test panel to be tested, using an analytical balance (5.2). Place the test panel on the
23、 panel holder, coated side to be tested facing up, and fix it using a screw. Prepare the two abrading arms with cleaned abrasive wheels, e.g. type CS 10 or the more abrasive CS 17 (see ASTM D 4060-01), and additional masses to make the total load typically 500 g or 1000 g. Place the arms on the test
24、 panel and start the abrader (speed fixed; typically 60 rpm, maximum 100 rpm) for a specified number of revolutions or until the substrate is exposed. A suction device continuously removes the debris from the test panel. The test can be interrupted after 250, 500, 1000 or more revolutions. If the su
25、bstrate is exposed, the test shall be stopped and no mass measurement is required. Otherwise the test panel is re-weighed. The loss of material i.e. difference in mass, in combination with the number of revolutions is a measure of the abrasion resistance. The wheels shall be cleaned after every 1000
26、 revolutions in a continuous test or before every new test, using a fresh refacing disc for 25 revolutions. Repeat the procedure for two further test panels. 9 Expression of results The result shall be expressed either by the mean of the mass loss after every specified number of revolutions or the m
27、ean of the number of revolutions until the substrate is just exposed. 10 Precision No precision data are available EN 13523-16:2004 (E) 5 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 p
28、art of EN 13523 (EN 13523-16); c) the total mass of the abrading arms; d) the type of wheels used; e) the result of the test, as indicated in clause 9; f) any deviation from the test method specified; g) the date of the test.
