Slip resistance - regulations and safety standards

GriP anti-slip is the world's only anti-slip coating that has been comprehensively tested and certified. Below you will find testing methodes and standards on slip resistance for the DACH countries. Furthermore for Australia, which has the world's highest requirement for slip resistance for pedestrian surfaces.

Testing: Pendulum vs inclined plane

Pendulum test to determine slip resistance and test on inclined plane are not considered comparable. While the pendulum tests are tests with calibrated equipment, the classification of slip resistance on inclined planes is performed by individuals with different characteristics (height, body weight, footwear, fitness). A comparison of the two classifications is therefore not possible. Consequently, the comparative values given here are cited in the technical literature exclusively as values for locations.

Testing: Pendulum vs inclined plane
Locations (selection) Pendulum Test: Wet Inclined plane:

Pavements and ramps, outdoor
Outdoor Slope angle > 1:14

P5 R12
Walkways and ramps, outdoor
Exterior slope angle < 1:14
Balconies, terraces, walkways, crossings, markets, car parks
P4 R11
Hotels, offices, public buildings, schools, day-care centers
Wet areas, toilets


Supermarkets and shopping centers P3 R10
Loading docks, commercial kitchens
Cold storage rooms, bar areas
Swimming pools and sports facilities
Pool ramps and stairs leading into the water
Pool surrounds and shower rooms

Slip resistance of floor coverings in Germany

  • DIN-Standards
    - DIN 51130 (Engine oil with safety shoes on sloping surfaces)
    - DIN 51131 (friction coefficient measuring devices)
    - DIN 51097 (wet barefoot areas on sloping surfaces)

DIN 51097 Slip resistance values / slip resistance classes - wet barefoot areas:

B 18° minimum angle Slip resistance class B
C 24° minimum angle Slip resistance class C


DIN 51130 Slip resistance values / slip resistance classes R-value: working areas with footwear:

Angle of inclination Application
R9 from 6° to 10° Slip resistance R9 Indoor floor coverings, e.g. offices.
R10 >10° – 19° Slip resistance R10 Floor coverings e.g. public toilets.
R11 >19° – 27° Slip resistance R11 Commercial entrances and outdoor stairs. Commercial kitchens in child care centers, nursing homes, sanatoriums, etc.
R12 >27° – 35° Slip resistance R12 Industrial kitchens.
R13 >35° Slip resistance R13 Slaughterhouses.

Slip resistance of floor coverings in Australia:

The Australian guidelines have been the world's most detailed and demanding standards for slip resistance of wet surfaces for pedestrians since 1999. The requirements have also been adopted by industries and companies outside Australia, such as cruise lines.

  • HB 198 Guidelines to the Specification and Testing of Slip Resistance of Pedestrian Surfaces was developed by the Australian Standards Committee BD-094, Slip Resistance of Flooring Surfaces. Manual 198 was published in 2014.
