Retrieved from ” https: Slips, trips and falls. In order to determine the sliding friction coefficient, this force is divided by the vertically acting force. The 5107 of dynamic friction measured with the GMG or with its predecessor, the GMGare evaluated as follows.
The method for measurement of the slip resistance of shoes is described in EN . No single test currently in use is perfect. At coefficients lower than 0. These devices are not covered by a standard at present.
PTVs can be obtained for dry surfaces and surfaces contaminated with fin.
DIN states provisions governing tribometers. This test requires an operator who is protected by a fall restraint harness.
Measuring the slip resistance of floorings and footwear
It envisages three classes for hard floor coverings:. Beginning with the ramp in a horizontal position, he gradually increases the angle of inclination until the limit of safe walking is reached and the test person slips.
The ramp test allows testing of all types of floorings, such as ceramics, granite, natural stone, timber, steel gratings and flexible materials. A widely used test is the ramp test according to the German norm DIN The slip resistance of the floor must be improved. This is the PTV pendulum test value. Five resistance classes R9 to R13, see Table 1 are used for this purpose.
However, ramp test work requires well-trained operators in order for reliable and reproducible results to be obtained.
Coverings are classified through the measurement of surface characteristics of the material primary surface parameters measured using optical topography techniques. The operator, wearing standard footwear, walks backwards and forwards over a sample of a flooring material that has been evenly coated with oil.
The pendulum does not always accurately measure heavily profiled surfaces. All have their advantages, but also their own particular flaws and disadvantages. The dib of footwear to be tested is placed on a ceramic tile or steel floor, subjected to a given normal force, and moved horizontally relative to the surface. Pendulum tests can be performed both in a lab and on-site. Retrieved 9 Junefrom: Floor coverings with the resistance class R9 satisfy the lowest requirements for slip resistance; those with class R13 the highest.
It exhibits an adequate slip resistance potential, and the risk of slipping is low even under unfavourable conditions, such as moisture.
The ramp test is also carried out barefoot with the use of soapy water as a contaminant DIN . This test is not suitable for on-site tests.
Measuring the slip resistance of floorings and footwear: OSHwiki
This device is predominantly used in Germany, Poland and Austria. Figure 2 shows as an example the GMG test device.
It was conceived as a joint approach to overcome the objections to and shortcomings of the various approaches outlined above.
The angle at 5097 slipping occurs is used to establish an A, B or C rating for the barefoot test Table 2 . Numerous different methods and devices have been developed over the years to measure the slip resistance of floorings and footwear.
