 | 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 | | Resistance to superficial deterioration for glazed tiles | Class I - IV | | Resistance to deep deterioration for non glaz. tiles / volume loss, mm ³ | Maximum of 300 mm ³ | | Chemical stability (except stability to influence fluoric acid and its connections – for non glaz. tiles | Corresponds | Chemical stability (except stability to influence fluoric acid and its connections – for tiles: Against acids and alkalis Against the substances leaving stains Against the chemical substances used in housekeeping Against the substances added in water in pools | Corresponds for the groups specified by the manufacturer on chemical stability | | Resistibility to occurrence of cracks and ruptures in glaze for glazed tiles | Corresponds | | The hardness of a surface defined by a method of a scratching on scale Mohs: for tiles, the minimum individual value | 5 | 5 | | Stability to difference of temperatures | Corresponds | | Factor of thermal expansion at temperature of a premise to 100 °С | 4х10-6/L-1 до 8х10-6L-1 | 5х10-6/L-1 до 13х10-6L-1 | | The hardness of a surface defined by a method of a scratching on scale Mohs: for tiles, the minimum individual value | 6 | 6 |
