DIN 51130:2014-02

This standard specifies a method which serves as a performance test for the determination and classification of the slip resistance of floor coverings used in workplaces and working areas where there is a risk of slipping. In addition, this standard specifies a method of measuring the volume of the displacement spaces in floor coverings with profiled surfaces. A tester wearing testing footwear walks forwards and backwards in an upright position across the floor covering to be tested, which is initially in a horizontal position and then gradually tilted until the acceptance angle has been reached. The acceptance angle is determined using a floor covering coated with lubricant. The mean acceptance angle reached is used to classify the degree of slip resistance. Subjective influences on the acceptance angle are limited by means of a calibration procedure. For determination of the displacement space the test specimen is levelled out by filling the profile cavities with paste until this is flush with the surface and its mass is measured before and after this process. The volume of the displacement space is calculated from the difference in mass and the density of the paste. The committee responsible for this standard is NA 062-08-82 AA "Prüfung der rutschhemmenden Eigenschaft von Bodenbelägen" ("Testing of the anti-slip property of floor coverings") at DIN.
