FAQ
To classify the anti-slip properties of floor coverings, German standard DIN 51130 tests each covering at 5 different angles of inclination in order to find the angle at which slipping begins. A material is deemed to have a low coefficient of friction when feet start slipping when the test ramp is set at a small angle.
