General Information & Regulations

Non-slip tiles are specialised tiles with different kinds of profiled or roughened surfaces. Accident insurers stipulate their use especially on work flooring, in commercial areas with an increased risk of slipping, and in moisture-prone barefoot areas.

These regulations do not apply to private households. There, non-slip tiles can be used – but do not have to be – in outdoor areas (e.g. terraces) and around swimming pools and saunas.

 

Work rooms, commercial and public areas

Tiles used in work rooms, commercial and public areas have to demonstrate a stipulated level of grippiness as categorised in evaluation groups R9 to R13 in DIN 51130 (proof furnished by manufacturer). In a test, the test-person has to stand and walk on a sloping surface while wearing protective shoes. Oil is applied to the surface as a lubricant. The greater the angle of inclination of the surface being tested, the higher the R group.

 

Evaluation group
Angle of inclination
 
R 9 >6°-10°
Low friction
Rutschhemmung - R 9 - Deutscher Industrieverband Keramische Fliesen + Platten e.V.
R 10 >10°-19°
Normal friction
Rutschhemmung - R 10 - Deutscher Industrieverband Keramische Fliesen + Platten e.V.
R 11 >19°-27°
Increased friction
Rutschhemmung - R 11 - Deutscher Industrieverband Keramische Fliesen + Platten e.V.
R 12 >27°-35°
High friction
Rutschhemmung - R 12 - Deutscher Industrieverband Keramische Fliesen + Platten e.V.
R 13 >35°
Very high friction
Rutschhemmung - R 13 - Deutscher Industrieverband Keramische Fliesen + Platten e.V.

Displacement groups V

Work rooms and areas in which a displacement space is necessary beneath the flooring because of the presence of particularly slippery substances are designated by a V in conjunction with the number indicating the minimum volume of the displacement space.

 

V groups
Minimum volume of displacement space
 
V 4 4 cm3/dm2 v4
V 6 6 cm3/dm2 v6
V 8 8 cm3/dm2 v8
V 10 10 cm3/dm2 v10

 

Moisture-prone barefoot areas

In barefoot areas in swimming pools, public saunas, around pools, and in cleaning areas at sports venues, flooring is categorised by DIN 51097 into groups A (lowest requirements), B and C (highest requirements). Again, grippiness is determined by a test-person walking on an inclined surface made slippery by water containing soap.

Non-slip categories range from A to B to C. A test-person walks upright back and forth along the flooring that is being tested. It begins level, then inclines until the test-person becomes unstable. Tiles in evaluation group A reach a minimum angle of inclination of 12° in this testing process, while B corresponds to a minimum angle of inclination of 18°, and C to 24°.

 

Slip resistance evaluation groups as per GUV.85.27 (formerly GUV.26.17)
