Ceramic tiles - Definitions, classification, characteristics and marking

This European Standard defines and gives terms, specifies requirements and marking criteria for ceramic tiles (produced by extrusion and dry-pressing techniques) of the best commercial quality (first quality). Tiles not of first commercial quality are also covered following the provisions of Annex Q. This European Standard does not cover tiles made by other than the normal processes of extrusion or dry-pressing nor decorative accessories or trim (such as edges, corners, skirting, capping, coves, beads, steps, curved tiles and other accessory pieces) or mosaics (i.e. any piece that can fit into a 7 cm  7 cm area, see custom nomenclature). NOTE EN ISO 10545 describes the test procedures required to determine the product characteristics listed in this European Standard. EN ISO 10545 is divided into parts, each describing a specific test procedure or related matter.
