This European Standard defi nes methods for determining the dimensional characteristics (length, width, thickness, straightness of sides, rectangularity, surface flatness) and the surface quality of all ceramic tiles.
Tiles with areas less than 4 cm2 are excluded from measure-ments of length, width, straightness of sides, rectangularity and surface flatness.
Spacer lugs and glaze blobs and other irregularities of the sides shall be ignored when measuring length, width, straightness of sides and rectangularity if these are subsequently hidden in the joints after fixing.
