This part is part 6 of GB/T 3810.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This part of the replacement GB/T 3810.6-2006 "ceramic tile test method Part 6. no glaze brick wear depth determination." this part of the main changes compared with GB/T 3810.6-2006 as follows.

--- modified the reference file (see Chapter 2, Chapter 2 of the 2006 edition);

--- modified abrasive requirements (see 4.3, version 4.3);

--- The corresponding values of chord length and volume are modified (see Table 1, version 1.26).

This part uses the translation method equivalent to ISO 10545-6.:2010 "Ceramic tiles Part 6. Determination of wear-resistant depth of glazed tiles" (English Version).

In this part of the normative reference to the international documents have a consistent correspondence between the following documents.

3 Principle

In the case of specified conditions and abrasive in the case of friction by the wheel in the brick rotation of the front of the grinding pit, measured by the length of the measured pit the abrasion resistance of glazed tiles.

4 Equipment

4.1 wear test machine (see Figure 1).

It consists of a friction wheel, a hopper with an abrasive feed device, a sample holder and a counterweight. Friction wheel is Made of ISO 630-1 steel, the diameter is.200mm ± 0.2mm, the edge thickness is 10mm ± 0.1mm, the speed is 75r/min.

The specimen is subjected to the reverse pressure of the friction wheel and is passed through the corundum adjustment test machine. Pressure adjustment with F80 (ISO 8486-1) corundum After the abrasive 150 turns, a grinding pit with a chord length of 24 mm ± 0.5 mm is produced. Quartz glass as a basic standard can also be used float glass or Other applicable materials.

When the friction wheel wears to 0.5% of the original diameter, the grinding wheel must be replaced.

4.2 Measuring tool with measuring accuracy of 0.1mm.

4.3 abrasive.

Conforms to F80 as specified in ISO 8486-1. Grinding materials that produce the same result can also be used.
