Understanding pictograms Pictograms Meaning Commercial / Domestic use classification This symbol indicates suitability for use of the floor covering. Correspondence between domestic and commercial use: Luxury class This symbol indicates the comfort level of the floor covering. Variable from LC1 to LC5. The highest comfort class is LC5 with 5 crowns. A flat needlepunched carpet and a carpet without velour are always classified LC1. Office chair with casters test / Castor chair This symbol indicates the wear resistance of the floor covering by simulating the traffic of a office chair with casters. Dimensional stability This symbol indicates that the floor covering is dimensionally stable. Commercial use Domestic use Good resistance for continuous use Good resistance for occasional use ≤0,2% Domestic use 21 22 23 Commercial use 31 32 33 Use class Use Domestic 21 Moderate 22 General 23 Heavy Commercial 31 Moderate 32 General 33 Heavy Une marque de

Sound absorption against impact noises This symbol indicates the sound absorption coefficient at shocks (αw) which is defined by the ratio between the absorbed noise and the incoming noise. This varies by sound frequency. The absorption coefficient is between 0 and 1: 0: the material does not absorb any noise, so the noise is totally reflected 1: all noise is absorbed by the material Acoustic insulation against impact noise This symbol indicates the performance of a floor covering against shock noise. It is measured in dB Slip resistance DS (Dry Slip resistance) This symbol indicates that the floor covering is slip resistant (coefficient of friction higher than 0.3). Slip resistance behaviour NPD (No Performance Determined) This symbol indicates that it has not been tested. Thermal resistance This symbol indicates whether the floor covering is suitable for use on a underfloor heating system.
