It is based on GB/T3810.2-2006 to determine the degree of unglazed ceramic tiles' property of wear-resistant.

1. Friction wheel speed: 75 ±4R/min;

  first grinding diameter: 200 ±0.2mm; thickness: 10 ±0.1mm, hardness: above HB500 (suitable for GB/T3810.7-2006),

  second grinding diameter: 200 ±0.2mm; thickness: 70 ±0.1mm, hardness: above HB500 (suitable for GB/T12988-91);

2. Materials entry speed: 100 ±10(g/100r);

3. Sample size: 100×150mm;

4. Abrasive particle size is white F80 alumina melt which is set in ISO 8486-1986;

5. Hoper volume is larger than 5L; first mass of pressure code: 2.5 KG, applicable standards: GB/T12988-91;

6. Friction has functions of computation and preset, which can set time to auto-complete the experiment.
