24、 Scope This part of ISO 1518 specifies a test method for determining under defined conditions the resistance of a single coating or a multi-coat system of paint, varnish or related product to penetration by scratching with a scratch stylus loaded with a specified load. Penetration of the stylus is t
25、o the substrate, except in the case of a multi-coat system, in which case the stylus can penetrate either to the substrate or to an intermediate coat. The method specified can be carried out a) either as a “pass/fail” test, by testing with a single specified load applied to the stylus to assess comp
26、liance with a particular specification; b) or by applying increasing loads to the stylus to determine the minimum load at which the coating is penetrated. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the
27、edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

28、ination of film thickness ISO 15528, Paints, varnishes and raw materials for paints and varnishes Sampling 3 Principle A scratch stylus loaded with a specified load is drawn over a coating at a constant speed. The following test parameters are specified: the geometry of the stylus tip; the range wit
29、hin which the test load may lie and the increments by which it may be increased; the procedure by which the stylus is lowered on to the coating; the speed at which the stylus travels and the minimum length of the scratch. DIN EN ISO 1518-1:2011-09 EN ISO 1518-1:2011 (E) 4 The scratch is examined to
30、see if the coating has been penetrated to the extent specified for a single specified test load (“pass/fail” test) or to determine the minimum test load required for penetration. 4 Apparatus 4.1 Scratch apparatus, two versions of which are illustrated in Figure 1 and Figure 2, with the following cha
31、racteristics: The test load acting on the scratch stylus fixed to the load beam can be produced either by a weight attached to the stylus (see Figure 1) or by a weight which slides along a graduated load beam (see Figure 2). The test load shall be 1 N to 20 N, shall be adjustable in increments of 0,
32、5 N and shall be accurate to within 0,2 N. The test panel held in a panel holder is moved relative to the stylus by means of a linear actuator driven by a motor. The speed at which the stylus travels shall be (35 5) mm/s and the length of the scratch shall be at least 40 mm. The length of the scratc
33、h can affect the result. A lowering device with a flat ramp brings the stylus smoothly into contact with the coating at the beginning of the movement of the panel holder. The angle of the ramp shall be (12,5 2,5). Some types of apparatus are designed so that the load beam moves and the test panel is
34、 fixed. Such types of apparatus may also be used. 4.2 Scratch stylus A, having a hemispherical hard-metal tip of radius (0,50 0,01) mm. 4.3 Scratch stylus B, having a hemispherical hard-metal tip of radius (0,25 0,01) mm. 4.4 Scratch stylus C, having a hemispherical synthetic-ruby tip of radius (0,5
35、0 0,01) mm. 4.5 Scratch stylus D, having a hemispherical synthetic-ruby tip of radius (0,25 0,01) mm. 4.6 Indicating device, based on electrical contact between the stylus and the metallic substrate, to show when the coating has been penetrated. NOTE 1 This device is not suitable for paints containi
36、ng electrically conducting pigments, for non-metallic substrates or if penetration to an intermediate non-conducting coat is required. NOTE 2 The indicating device can only be used when certain parts of the scratch apparatus are electrically insulated. 4.7 Magnifying lens, with at least 4 magnificat
37、ion. 5 Sampling Take a representative sample of the product to be tested (or of each product in the case of a multi-coat system), as described in ISO 15528.

The panels should preferably have a size of 200 mm 100 mm. 6.2 Preparation and coating
41、Prepare each test panel in accordance with ISO 1514 and coat it according to the specified method with the product or system under test. The method of application of the coating shall be as specified by the manufacturer or agreed between the interested parties and shall be included in the test repor
42、t see Clause 9, item c) 2). 6.3 Drying and conditioning Dry (or stove) and age, if applicable, each coated test panel for the specified time and under the specified conditions. Before testing, condition the coated panels at a temperature of (23 2) C and a relative humidity of (50 5) % (i.e. in accor
43、dance with ISO 3270) for a minimum period of 16 h. Carry out the test procedure immediately after the removal of the test panels from the conditioning chamber. The drying (or stoving) and ageing time and conditions shall be as specified by the manufacturer or agreed between interested parties and sh
44、all be included in the test report see Clause 9, item c) 3). 6.4 Thickness of coating Determine the thickness, in micrometres, of the dried coating by one of the procedures specified in ISO 2808. The dry-film thickness shall be as specified by the manufacturer or agreed between the interested partie
45、s and shall be included in the test report see Clause 9, item c) 4). 7 Procedure 7.1 Test conditions Carry out the test at (23 2) C and a relative humidity of (50 5) %. 7.2 General test procedure 7.2.1 Clamp a coated test panel on the panel holder with the coating facing upwards. Position the test p
46、anel so that the distance between the scratches to be made will be at least 5 mm and the distance from the scratches to the edge of the test panel will be at least 10 mm. 7.2.2 Fix the scratch stylus in the load beam so that, when in position on the test panel, the stylus will be perpendicular to th
47、e panel. 7.2.3 With the stylus unloaded, balance the load beam by means of the tare weight. 7.2.4 Adjust the test load to the required value by placing a weight on the stylus or by moving the sliding weight, depending on the type of apparatus used. 7.2.5 Activate the indicating device, if used, and
48、check that it is functioning correctly. DIN EN ISO 1518-1:2011-09 EN ISO 1518-1:2011 (E) 7 7.2.6 Start the motor of the apparatus and allow the scratch to be made in the coating. Observe the indicating device during the test, if appropriate, to determine whether electrical contact occurs between the
49、 stylus and the substrate. 7.2.7 Remove the panel and immediately examine the scratch, with the aid of the magnifying lens, for penetration to the extent specified. 7.3 Procedure for a single specified load (“pass/fail” test) Carry out the procedure specified in 7.2 three times on each of two test panels. If the coating has not been penetrated beyond the specified extent in any of the six test runs, report the result as “pass”. If the coating has been penetr
