22、 resistance to surface abrasion for glazed tiles Part 8: Determination of linear thermal expansion Part 9: Determination of resistance to thermal shock Part 10: Determination of moisture expansion Part 11: Determination of crazing resistance for glazed tiles Part 12: Determination of frost resistanc
23、e Part 13: Determination of chemical resistance Part 14: Determination of resistance to stains Part 15: Determination of lead and cadmium given off by glazed tiles Part 16: Determination of small colour differences 1 ScopeThis part of ISO 10545 defines a test method for determining the coefficient o
24、f linear thermal expansion of ceramic tiles.2 PrincipleDetermination of the linear thermal expansion coefficient for the temperature range from ambient temperature to 100 C.3 Apparatus3.1 Suitable thermal expansion apparatus, capable of a rate of heating of (5 1) C/min with uniform distribution of h
25、eat. Certain types of apparatus require a soaking time at 100 C.3.2 Vernier calipers, or other suitable device.3.3 Drying oven, capable of being operated at (110 5) C. Microwave, infrared or other drying systems may be used provided that it has been determined that equal results are obtained.3.4 Des
26、iccator4 Test specimensCut two test specimens at right angles from the central portion of one tile so that their lengths are suitable for the apparatus. The ends of the test specimens shall be ground flat and parallel.If necessary, grind the test specimens so that the length of any side in cross-sec
27、tion is less than 6 mm and the area of cross-section is greater than 10 mm2. The minimum length of the test specimens should be 25 mm. In the case of glazed tiles, the glaze shall not be ground off the test specimens.5 ProcedureIt is necessary to make a previous calibration of the apparatus with a s
28、tandard test specimen. The dimensions of the standard test specimen shall be the same as the dimensions of the test specimen.Dry the test specimens at (110 5) C until they reach constant mass, i.e. when the difference between two successive weightings at intervals of 24 h is less than 0,1 %. Allow t
29、hem to cool in the desiccator (3.4) at ambient temperature.Using vernier calipers (3.2), determine the lengths to an accuracy of 0,002 times the length.Place a test specimen in the apparatus (3.1) and record the ambient temperature.4DIN EN ISO 10545 8:2014 09 - -EN ISO 10545-8:2014 (E) Initially, an
30、d throughout the heating procedure, measure the length to an accuracy of 0,01 mm. Take temperature and length measurements at temperature intervals of no more than 15 C.The rate of heating shall be (5 1) C/min.6 Expression of resultsThe linear thermal expansion coefficient, l, is expressed in 106per
31、 degree Celsius (106/C), to the first decimal place, in accordance with the expression:lLxLT=1owhereLois the length of the test specimen at the ambient temperature;L is the increase in length of the test specimen between ambient temperature and 100 C;T is the rise in temperature.7 Test reportThe test report shall specify the following:a) reference to this part of ISO 10545, i.e. ISO 10545-8;b) a description of the tiles, including sample preparation;c) the linear thermal expansion coefficient for both test specimens.5DIN EN ISO 10545-8:2014-09EN ISO 10545-8:2014 (E)
