Quality DIN EN 121
Requirements at water absorption to 3%
Characteristic Surface from ceramic tiles with seams Separate ceramic tiles
Width and length: maximum deviations from factory values, %
±1,25% ±2%
Thickness: maximum deviations from factory values, % ±10% ±10%
Straightforwardness of the parties: maximum deviations in relation to lengths of the parties, % ±0,5% ±0,6%
Flatness of a surface: maximum deviations – settlement value - a bend (curvature) in relation to a diagonal, exceeding value of the factory size, % ±0,5% ±1,5%
Quality (character) of a surface: a share (%) of the accepted tiles Minimum of 95 % of tiles should be without damages of a surface which will be distinguishable on the big area of the laid tile
Water absorption:
• individual value, %
• average value, %
• On the average ≥ 3
• the Maximum individual value = 3,3
Durability on a bend, N/mm ² • On the average ≤ 20
• the Minimum individual value = 18
Frost resistance Correspond
