General Information & Regulations

Anti-slip tiles are special tiles with different profiled or rough surfaces. Accident insurers require these specifically for floors in work spaces, especially in the commercial sector with an increased risk of slipping, as well as for wet-contaminated barefoot areas.

These rules do not apply to households. Here, however, non-slip tiles can be used outdoors (e.g. terraces) or in connection with swimming pools or saunas.


Workspaces, commercial and public areas

Tiles used in work spaces, commercial and public areas must have the prescribed degree of slip resistance in accordance with evaluation groups R9 to R13 in accordance with DIN 51130 (proof by the manufacturer). During the test, an examiner must stand and walk on a skewed plane with protective shoes. As a lubricant, oil is applied to the surface. The larger the angle of inclination of the surface to be tested, the higher the R group.

Evaluation group

Tilt angle

R 9

> 6° - 10°

Low static friction coefficient

R 10

> 10° - 19°

Normal static friction coefficient

R 11

 > 19° - 27°

Increased coefficient of static friction

R 12

> 27° - 35°

High static friction coefficient

R 13

> 35°

Very high coefficient of static friction

Displacement groups V

The working areas and areas in which a displacement space below the walking plane is required due to the seizure of special sliding substances are indicated by a V in conjunction with the measure for the minimum volume of the displacement space.

Wet-contaminated barefoot areas

In the case of barefoot areas in swimming pools, public pools, by the pool and in cleaning areas of sports facilities, the evaluation is carried out in groups A (lowest requirements), B and C (highest demands) in accordance with DIN 51097. Here, too, the slip resistance is determined by means of a test person at the sloping level, the lubricant is soapy water.

The required slip resistance increases from A to B to C. An examiner moves forwards and backwards on the floor covering to be tested in an upright position. Its inclination is increased from the horizontal to the angle at which the test person becomes unsafe. In this test procedure, tiles of evaluation group A achieve a minimum angle of inclination of 12°, B corresponds to a minimum angle of inclination of 18° and C of 24°.
