17、ards 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. International orga
18、nizations, 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 the rules given
19、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 by at least 75
20、% 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.

26、hod 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 document.

28、f 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 Apparatus 4.1 Abrasion apparatus, consisting essentially of a rotating disc, a storage h
29、opper 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) mm and a thickness at the edge of (10 0,1) mm, and with a revolution rate of 75 r/min
30、. 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 revolutions using F80 abrasive, which shall be in accordance with ISO 8486-1, a chord of
31、 (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 diameter, the steel disc shall be replaced. 4.2 Measuring gauge, accurate to 0,1 mm. BS

An equivalent abrasive material may be used if it can be shown to lead to the same results. 5 Test specimens 5.1 Types o
33、f 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 specimens Clean, dry test specimens shall be used. 5.3 Number of
34、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 the grinding zone at a rate of (100 10) g/100 revolutions. Rotate th
35、e 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 at right angles to each other. In the case of relief surfaces inter
36、fering 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 Expression of results The resistance to deep abrasion is expressed as the
37、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 the rotating disc by the chord (see Figure 2); h is the thickness,
