Anti-slip properties

ANTI-SLIP PROPERTIES     DIN 51130, DIN 51097

At the moment there is no European norm that determines the demands for slip resistance. But as in everyday use the slip resistance can be very important we inform you using the current German standards.
The slip resistance is influenced by maintenance and wear.

The standards distinguish between the slipperiness of floor surfaces in areas where people walk with their shoes on (R9-R13) and with bare feet (A,B,C). The R level indicates the angle of slippage.

The measurement method specified in DIN 51130 distinguishes among the following slipperiness classes and provides indications as to where they may be used:

  • R9 (6°- 10°) entrances and stairways accessed from outside; restaurants; shops; clinics; hospitals; schools.
  • R10 (10° - 19°)  shared toilets and showers; small kitchens in restaurants and cafés; garages and basements.
  • R11 (19°- 27°) food production facilities; mid-sized kitchens in restaurants and cafés; working environments where there is a lot of water and sludge; laboratories; laundries; hangars.
  • R12 (27°- 35°) production facilities for foods rich in fats such as dairy products, food oils, cured meats; large kitchens in restaurants and cafés; industrial areas where slipper substances are used.
  • R13 (>35°) places where large quantities of fats are used; food processing areas.

The slip resistance for areas where people walk with bare feet is divided into categories from A, B to C.

    A –  dry areas where people walk barefoot and changing rooms.

    B – showers, bathrooms, areas surround swimming pools, children’s swimming pool, bottom of shallow pools.

              C – crossing area in swimming pool, tilted edges of swimming
