Depending on the test conditions, the friction coefficients must fulfil certain requirements given in EN Table 4 [8].

Testing and assessment of anti-slip characteristics is of major importance for the prevention of slipping accidents. Retrieved 9 Junefrom: The pendulum does not always accurately measure heavily profiled surfaces. 510997 device is predominantly used in Germany, Poland and Austria. The force required to pull the body is determined over the length of the measuring distance.

Figure 2 shows as an example the GMG test device. The acceptance angle obtained is used to express the degree of slip resistance. It exhibits an adequate slip resistance potential, and the risk of slipping is low even under unfavourable conditions, such as moisture. The pendulum test measures the loss of energy due to friction as the standard rubber-coated slider assembly slides 15097 the test surface. It was conceived as a joint approach to overcome the objections to and shortcomings of the various approaches outlined above.

Slips, trips and falls. Coverings are classified through the measurement of dij characteristics of the material primary surface parameters measured using optical dih techniques. Glycerine or sodium lauryl sulphate solution acts as contaminant on the surface. Where the coefficient of friction exceeds 0.

The slip resistance of the floor must be improved. Barefoot ramp tests are useful in wet areas, such as swimming pools and saunas. If coefficients of friction of between 0. However, ramp test work requires well-trained operators in order for reliable and reproducible results to be obtained. Some such devices are considered to give over-optimistic slip resistance readings on wet, polished or glazed surfaces. This test can be carried out in wet and in dry conditions both in a laboratory and on-site.


PTVs can be obtained for dry surfaces and surfaces contaminated with water.

Measuring the slip resistance of floorings and footwear

51907 The ramp test is also carried out barefoot with the use of soapy water as a contaminant DIN [3]. This test method is based upon a friction force measurement.

An acute risk of slipping exists. Because these test methods are based on different principles and are used under different conditions there is no correlation between them. It provides a standardized value of slip resistance [4].

The ramp test allows testing of all types of floorings, such as ceramics, granite, natural stone, timber, steel gratings and flexible materials. Numerous different methods and devices have been developed over the years to measure the slip resistance of floorings and footwear. Retrieved from ” https: This test is not suitable for on-site tests.

Measuring the slip resistance of floorings and footwear: OSHwiki

The ramp test is the preferred test method for instance in Germany, France and the Benelux countries. Dij coefficients of dynamic friction measured with the GMG or with its predecessor, the GMGare evaluated as follows. The pendulum is the preferred test method in the United Kingdom and Spain. 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.

This test requires an operator who is protected by a fall restraint harness. A body equipped with sliders is pulled at a constant speed over the flooring surface. The method for measurement of the slip resistance of shoes is described in EN [7]. No single test currently in use is perfect. Different European countries have adopted various test methods and rating systems.

The operator, wearing standard footwear, walks backwards and forwards over a sample of a flooring material that has been evenly coated with oil. Measuring the slip resistance of floorings and footwear. Floor ddin with the resistance class R9 satisfy the lowest requirements for slip resistance; those with class R13 the highest.

A widely used test is the ramp 511097 according to the German norm DIN It envisages three classes for hard floor coverings:. Personal tools Log in. Pendulum tests can be performed both in a lab and on-site. Five resistance classes R9 to R13, see Table 1 are used for this purpose. These devices are not covered by a standard at present. In order to determine the sliding friction coefficient, this force is divided by the vertically acting force.

The ramp test can also be used to determine the slip resistance of profiled surfaces. The item 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. Co-financed by the European Commission, the SlipSTD project had the objective to define common ‘European’ minimum slip resistance requirements for ceramic tiles based on defined and measurable surface properties in preference to traditional slip resistance testing.

To a certain degree this test method takes into account the human walk. At coefficients lower than 0. The angle at which slipping occurs is used to establish an A, B or C cin for the barefoot test Table 2 [2]. All have their advantages, but also their own particular flaws and disadvantages.
