21、2 (E) DIN EN ISO 10545-6:2012-05 3 1 Scope This part of ISO 10545 specifies a test method for determining the resistance to deep abrasion of all unglazed ceramic tiles used for floor coverings. 2 Normative references The following referenced documents are indispensable for the application of this do
22、cument. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

23、n of grain size distribution Part 1: Macrogrits F4 to F220 3 Principle Determination of the abrasion resistance of unglazed tiles by measuring the length of the groove produced in the proper surface by means of a rotating steel disc, under given conditions and with the use of abrasive material. 4 Ap
24、paratus 4.1 Abrasion apparatus, consisting essentially of a rotating disc, a storage hopper with a dispensing device for the abrasive material, a test specimen support and a counterweight (see Figure 1). The disc shall be made of E 235 A (Fe 360 A) conforming to ISO 630, with a diameter of (200 0,2)
25、 mm and a thickness at the edge of (10 0,1) mm, and with a revolution rate of 75 r/min. The pressure with which the test specimens are held against the steel disc shall be determined by calibrating the apparatus against transparent fused silica. The pressure shall be adjusted such that, after 150 re
26、volutions using F80 abrasive, which shall be in accordance with ISO 8486-1, a chord of (24 0,5) mm shall be produced. Transparent fused silica shall be used as a primary standard. A secondary standard of float glass or other products may be used. When the diameter has worn by 0,5 % of the initial di
27、ameter, the steel disc shall be replaced. 4.2 Measuring gauge, accurate to 0,1 mm. EN ISO 10545-6:2012 (E) DIN EN ISO 10545-6:2012-05 44.3 Abrasive material, of white fused aluminium oxide with a grain size of F80, in accordance with ISO 8486-1. An equivalent abrasive material may be used if it can
28、be shown to lead to the same results. 5 Test specimens 5.1 Types of test specimen Tests shall be carried out using whole tiles or test specimens of suitable dimensions. Before testing, small specimens shall be fixed with an adhesive on to a larger background, avoiding joints. 5.2 Preparation of test
29、 specimens Clean, dry test specimens shall be used. 5.3 Number of test specimens A minimum of five test specimens shall be tested. 6 Procedure Place a test specimen in the apparatus (4.1) so that it is tangential against the rotating disc. Ensure that abrasive material (4.3) is fed uniformly into th
30、e grinding zone at a rate of (100 10) g/100 revolutions. Rotate the steel disc for 150 revolutions. Remove the test specimen from the apparatus and measure the chord length, L, of the groove to the nearest 0,5 mm (see Figure 2). Test each test specimen on its proper surface, in at least two places a
31、t right angles to each other. In the case of relief surfaces interfering with the determination of the abrasion resistance, the projections may be ground off, but the results of the test would not be the same as for similar tiles having plane surfaces. Do not re-use the abrasive material. 7 Expressi
32、on of results The resistance to deep abrasion is expressed as the volume, V, in cubic millimetres, of material removed, and is calculated from the chord length, L, of the groove using the following equation: 2sin180 8hdV= with ()sin 0,5Ld = where is the angle, in degrees, subtended at the centre of
33、the rotating disc by the chord (see Figure 2); h is the thickness, in millimetres, of the rotating disc; EN ISO 10545-6:2012 (E) DIN EN ISO 10545-6:2012-05 5 d is the diameter, in millimetres, of the rotating disc; L is the maximum length, in millimetres, of the chord. Some equivalent values of L an
34、d V are given in Table 1. 8 Test report The test report shall include the following information: a) reference to this part of ISO 10545, i.e. ISO 10545-6; b) a description of the tiles; c) the chord length, L, of each groove, to the nearest 0,5 mm; d) the volume, V, in cubic millimetres, for each in
35、dividual groove; e) the average volume, Vm, in cubic millimetres.
