Safe Environments provide independent ceramic tile classifications and natural stone tiling ceramic tile classifications.
They are actively involved in research presenting at the Qualicer, The World Congress of Ceramic Tile Quality and contribute to Australian Standards Committee Member BD-044 Fixing of Ceramic, Natural and Reconstituted Stone Tiles and the Australian Tile Council.
Ceramic tiles Classification is made according to their method of manufacture (i.e. dry pressed or extruded). They are also classified according to their water absorption characteristics. The Ceramic Tile classification then determines the physical and chemical properties required when tested to AS 4459 Methods of sampling and testing ceramic tiles.
AS 4662-2003 Ceramic tiles - Definitions, classification, characteristics and marking is the applicable Australian Standard of Ceramic Tile Classification. It determines if a ceramic tile is of the best commercial quality (first quality).
