Slip resistance

The slip resistance or anti-slip characteristics of a floor or road material determines the safety for pedestrians, cyclists and fast-moving traffic. The determination of these characteristics is a complicated business. TCKI has various measuring techniques to gain insight into this.

Walking method-ramp measurement
A measuring technique that can only be implemented in the laboratory is the so-called ramp measurement method. A test walker determines the maximum incline angle at which the tester can still walk on the relevant floor material. There are various options: barefoot or with specific footwear and with soapy water or oil as contaminant. Tests are conducted according to DIN 51130, DIN 51097 and CEN/TS 16165.

Pendulum method
A measurement technique that is used both inside and outside the laboratory on a floor or road surface is the pendulum method (also called the SRT method). Here we measure the extent of overshoot of a rubber slider. This slider is attached to the pendulum arm. The surface characteristics of the material determines the extent of overshoot of the slider when moving the slider over the surface. There are two types of rubber that are used for this slider. The test is usually performed with water as a contaminant. Fresh materials and products are sometimes also polished in order to evaluate the durability of the slip resistance of a product (the so-called PSRV is determined in addition to the USRV).
The test is RvA accredited and is conducted e.g. in accordance with EN 1338, EN 1344, EN 13036-4, EN 1436 and CEN/TS 16165.

Dynamic friction coefficient, pull slider-method
A third measuring technique, which can be implemented both in the laboratory and on site on a floor or road material, determines the dynamic friction coefficient. A GMG 200 apparatus is dragged over a certain length of the surface that requires testing and measures the dynamic friction coefficient of this length of surface. Three rubber blocks, attached to the bottom of the measurement box, are dragged over the test surface in this process.
Tests are conducted according to EN 13893, DIN 51131 and CEN/TS 16165.

TCKI has the knowledge and experience to measure and evaluate slip restistance or anti-slip properties of floor and road materials. Measurements can be conducted both in the laboratory and on site.
