The machine is used to test the resistance to wear of ceramictiles according to the “Mazaud” method, as per standardCSTB Cahier 3659_V3 2010 annex 10 for U4 classification(with particular reference to exports to France).The test consists in placing a tile measuring 300×300 mm ontoa special rotating plate driven by a gear motor. The upper partof the tile is scored by a stainless steel wheel with neutral gearmovement. The wheel applies an overall force of 590 N on thetile. The test is performed with 22.320 revolutions (whichare equal to a run of 14.000 m) at 93 rpm.At the end of the test, the glazed surface of the tile is visuallyinspected to check its degree of deterioration.The machine is made up of an oven-painted metal structurewith levelling feet.It has an electric cabinet with programmable operator paneland opening external safety hatches with safety microswitchlocks. The working chamber is internally soundproofed withsoundproofing panels. It has a power socket, fitting for compressedair and for a connection pipe to the dust extractionsystem.
