Surface Abrasion of glazed ceramic surfaces
Suitable for carrying out P.E.I. (wet) method tests in accordance with UNI EN ISO 10545-7 norm. The test involves exposing the glazed material to the abrasive action of a charge comprising balls of different diameters with the addition of corundum and distilled water (P.E.I. method). The different abrasion stages are achieved by programming the machine at an increasingly higher number of revs, with fixed instrument speed as required by the standard. Later on, a visual analysis of the test result will classify it in the various abrasion groups envisaged by the method.
