If coefficients of friction of between 0. The ramp test allows testing of all types of floorings, such as ceramics, granite, natural stone, timber, steel gratings and flexible materials.

Personal tools Log in. 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. These devices are not covered by a standard at present. The method for 5107 of the slip resistance of shoes is described in EN [7].

The ramp test is also carried out barefoot with the use of soapy water as a contaminant DIN [3]. The pendulum test measures the loss of energy due to friction as the standard rubber-coated slider assembly slides across the test surface. DIN states provisions governing tribometers. This test method is based upon a friction force measurement. Co-financed by the European Commission, the SlipSTD project had the objective to define common ‘European’ minimum slip resistance requirements for ceramic dun based on defined and measurable surface properties in preference to traditional slip resistance testing.

The coefficients of dynamic friction measured with the GMG or with its predecessor, the GMGare evaluated as follows. The acceptance angle obtained is used to express the degree of slip resistance. Where the coefficient of friction exceeds 0. The ramp test is the preferred test method for instance in Germany, France and the Benelux countries.

Testing and assessment of anti-slip characteristics is of major importance for the prevention of slipping dij.

This test requires an operator who is protected by a fall restraint harness. Barefoot ramp tests are useful in wet areas, such as swimming pools and saunas. The angle at which slipping occurs is used to establish an A, B or C rating for the barefoot test Table 2 [2]. It exhibits an adequate slip resistance potential, and the risk of slipping is low even under unfavourable conditions, such as moisture.

Measuring the slip resistance of floorings and footwear

An acute risk of slipping exists. At coefficients lower than 0. Five resistance classes R9 to R13, see Table 1 are used for this purpose. This test is not suitable for on-site tests. The pendulum is the preferred test method in the United Kingdom and Spain.

PTVs can be obtained for dry surfaces and surfaces contaminated with water. The item of footwear to be tested is placed on a ceramic tile or steel floor, subjected to a given normal force, di moved horizontally relative to the surface. Measuring the slip resistance of floorings and footwear. Retrieved 9 Junefrom: Retrieved from ” https: No single test currently in use is perfect. It was conceived as a joint approach to overcome the objections to and shortcomings di the various approaches outlined dinn.

This test can be carried out in wet and in dry conditions both in a laboratory and on-site. It provides a standardized value of slip resistance [4]. Depending on the test conditions, the friction coefficients must fulfil certain requirements given in EN Table 4 [8].

It envisages three classes for hard floor coverings:. This is the PTV pendulum test value.

In order to determine the sliding friction coefficient, this force is divided 511097 the vertically acting force. Pendulum tests can be performed both in a lab and on-site.

The pendulum does not always accurately measure heavily profiled surfaces. Different European countries have adopted various test methods and rating systems.

Measuring the slip resistance of floorings and footwear: OSHwiki

Coverings are classified through the measurement of surface characteristics of the material primary surface parameters measured using optical topography techniques. Because these 50197 methods are based on different principles and are used under different conditions there is no correlation between them.

Some such devices are considered to give over-optimistic slip resistance readings on wet, polished or glazed surfaces.

Ddin device is predominantly used in Germany, Poland and Austria. The frictional force is measured and the dynamic coefficient of friction is calculated. A body equipped with sliders is pulled at a constant speed over the flooring surface. The slip resistance of the floor must be improved. Glycerine or sodium lauryl sulphate solution acts as contaminant on the surface. To a certain degree this test method takes into account the human walk.

If necessary, a new floor must be installed. Numerous different methods and devices have been developed over the years to measure the slip resistance of floorings and footwear. A widely used test is the ramp test according to the German norm DIN
