TILES AND CERAMIC SLABS. Part 11. Determination of glaze crack resistance. Glazed tiles and slabs. German edition EN ISO 10545-11:1996 (ISO 10545-11:1994)
Application area
This standard specifies a test method for determining the cracking resistance of glazes on ceramic tiles and slabs, unless glaze cracking is a characteristic feature of the product.
Note : Requirements for the performance of tiles and slabs, as well as other information on these products, are contained in ISO 13006, Ceramic tiles and slabs - Definitions, classification, characteristics and labeling.
Essence of the method
To determine the resistance to cracking of the glaze, all tiles and slabs are subjected to high pressure steam in an autoclave. Then the tiles and slabs, after applying the dye to the glazed surfaces, are examined for the presence of cracks in the glaze.
