24、f national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. In
25、ternational organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with
26、the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval
27、 by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 2815 was prepared by Technical Committee I
28、SO/TC 35, Paints and varnishes, Subcommittee SC 9, General test methods for paints and varnishes. This second edition cancels and replaces the first edition (ISO 2815:1973), which has been technically revised. The main changes are as follows: only indentation length is now determined; the conversion
29、 of indentation length to indentation resistance is described in an informative annex. EN ISO 2815:2003 INTENRATIONAL TSANDADR IS:5182 O3002(E) I SO 3002 All irhgts seredevr 1 Paints and varnishes Buchholz indentation test 1 Scope This International Standard describes a method for carrying out an in
30、dentation test on a single coating or multicoat system of paint, varnish or related product, using a Buchholz indentor. The length of the indentation produced is indicative of the residual deformation of the coating. This indentation test is not suitable for products which contain a strong plasticiz
31、er. NOTE 1 Since the indentation test, like other physical tests on paints, gives results which can be dependent upon time, temperature and humidity, comparable results will only be obtained if the test is carried out under well-defined conditions. NOTE 2 Since the indentation depth depends upon the
32、 film thickness, the result obtained for the indentation length is only valid if the coating thickness exceeds a certain minimum value (see Annex A). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the editi

The indentation length is measured in millimetres (see Annex A). 4 Apparatus 4.1 Indent
35、ation apparatus This is shown in Figure 1. It consists essentially of a rectangular block of metal, which forms the body of the instrument, an indentor and two pointed feet.

36、indentor is a sharpened sharp-edged metal wheel of hardened tool steel. The cross-section through its axis of rotation and its dimensions shall be as shown in Figure 2.

38、at, when the instrument is placed on a level surface, it is stable, its upper surface is horizontal and the effective load upon the indentor is (500 5) g. 4.2 Measuring device A suitable device for measuring the length of the indentation consists of a microscope with 20 magnification and an eyepiece
39、 fitted with a graduated scale capable of reading to 0,1 mm. The area of indentation shall be illuminated by means of a light source located so that the angle of incidence of the light exceeds 60, as shown in Figure 4. The microscope shall be positioned vertically over the illuminated area and focus
40、ed to bring the shadow produced by the indentation (see Figures 4 and 5) and the graduated scale together. NOTE The position of the indentation mark can be located by means of a suitable template prepared from a triangular sheet of transparent plastics film (see Figure 6). Key 1 light source 2 micro

43、n the case of a multicoat system), as described in ISO 15528. The sample shall then be examined and prepared for testing as described in ISO 1513. 6 Test panels 6.1 Materials and dimensions Unless otherwise agreed, the test panels shall be of metal or glass conforming to the requirements of ISO 1514
44、. The test panels shall be flat and free from distortion, and the surface shall be free from any visible ridges or cracks. EN ISO 2815:2003 IS:5182 O3002(E) I SO 3002 All irhgts seredevr 5 Unless otherwise agreed, the test panels shall have minimum dimensions of 150 mm 100 mm and a thickness of not
45、less than 0,75 mm. NOTE The test panels may be cut to size after coating and drying, provided no distortion occurs. 6.2 Preparation and coating of panels The test panels shall be prepared in accordance with ISO 1514, unless otherwise agreed, and shall then be coated by the specified method with the
46、product or system under test to the specified film thickness limits. Any variation from the requirements of ISO 1514 shall be noted in the test report (see Clause 10). 6.3 Drying and conditioning of the test panels The coated test panels shall be dried (or stoved) and aged (if applicable) for the sp
47、ecified time and under the specified conditions and, unless otherwise specified, shall be conditioned at a temperature of (23 2) C and a relative humidity of (50 5) % for a minimum of 16 h. The test procedure shall then be carried out as soon as possible. 6.4 Thickness of coating The average thickne
48、ss, in micrometres, of the dry coating in the region to be tested shall be determined by the method specified, using one of the procedures specified in ISO 2808. 7 Procedure 7.1 Ambient conditions The test shall be carried out at a temperature of (23 2) C and a relative humidity of (50 5) %, unless
49、otherwise agreed. 7.2 Determination of indentation length Place the test panel, paint film uppermost, on a firm horizontal surface. Take the indentation apparatus (4.1) and place it gently and without any tilting or lateral movement on the test panel, leave the indentor in position for (30 1) s and remove it carefully. When the apparatus is put in place, the feet of the apparatus shall first
