ABRASION TESTER for NATURAL STONES and CONCRETE TILES
CODE : R197
Used to determine the abrasion-resistance of the natural stones and tiles. The test is carried out by abrading the face of a specimen which will be exposed in use with an abrasive material under standard conditions.
The abrasive required for this test is corundum (white fused alumina) with grit size of 80 in accordance with standard FEPA 42 F 1984. It shall not be used more than three times. (should be ordered separately)
The Abrasion Tester is essentially composed of a wide abrasion disc, a storage hopper, a clamping trolley, and a counterweight.
The wide abrasion disc diameter is 200 ± 1 mm and having a width of 70 ± 1 mm. It is driven to rotate 75 revolutions in (60 ± 3) seconds.
A mobile clamping trolley is mounted on bearings and forced to move forwards to the wheel by a counterweight having a mass of 14 ± 0,01kg.
