The

23、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. International organizations, governmental and non-gover

24、nmental, 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 the rules given in the ISO/IEC Directives, Part 2. Th

25、e 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 by at least 75 % of the member bodies casting a vote

26、. 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 ISO/TC 35, Paints and varnishes, Subcommittee SC 9, Ge

27、neral 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 of indentation length to indentation resistance is d

28、escribed in an informative annex. ENISO2815:2003INTENRATIONAL TSANDADR IS:5182 O3002(E)I SO 3002 All irhgts seredevr 1Paints and varnishes Buchholz indentation test 1 Scope This International Standard describes a method for carrying out an indentation test on a single coating or multicoat system of

29、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 plasticizer. NOTE 1 Since the indentation test, like other physical

30、 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 film thickness, the result obtained for the indentation l

31、ength 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 edition cited applies. For undated references, the latest editi

32、on of the referenced document (including any amendments) applies.

The indentation length is measured in millimetres (see Annex A). 4 Apparatus 4.1 Indentation apparatus This is shown in Figure 1. It consists ess

34、entially of a rectangular block of metal, which forms the body of the instrument, an indentor and two pointed feet.

37、, 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 fitted with a graduated scale capable of reading to 0,1 mm. The a

38、rea 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 focused to bring the shadow produced by the indentation (see Figures 4

39、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).

41、 position of the indentation 4.3 Timing device Use a stopwatch or other suitable timing device capable of measuring 30 s to the nearest 1 s. 5 Sampling Take a representative sample of the product to be tested (or of each product in the case of a multicoat system), as described in ISO 15528. The samp

42、le 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. The test panels shall be flat and free from distortion, and the surf

43、ace shall be free from any visible ridges or cracks. ENISO2815:2003IS:5182 O3002(E) I SO 3002 All irhgts seredevr 5Unless otherwise agreed, the test panels shall have minimum dimensions of 150 mm 100 mm and a thickness of not less than 0,75 mm. NOTE The test panels may be cut to size after coating a

44、nd 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 product or system under test to the specified film thickness limits. Any v

45、ariation 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 specified time and under the specified conditions and, unless otherwise spec

46、ified, 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 thickness, in micrometres, of the dry coating in the region to be tested shall be

47、 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 otherwise agreed. 7.2 Determination of indentation length Place the test p

48、anel, 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 be allowed to
