3 Terms and definitions
The following terms and definitions as defined in GB/T 9195 and GB/T 4100 apply to this document.
3.1 Anti-slip performance slipresistance
Reduces the risk of slippage between the pedestrian and the surface of the ceramic tile.
[GB/T 35153-2017, definition 3.1]
3.2 Static friction
When there is a tendency to move in a horizontal direction between an object that is stationary on a horizontal plane and a horizontal plane, the object is subjected to a horizontal plane.
The force that prevents this relative movement trend.
Note. Static friction will increase as this relative motion trend increases, until the maximum static friction produces relative motion.
3.3 Static friction coefficient
The ratio of the maximum static friction to the pressure exerted by the object on the horizontal plane.
3.4 Pendulum slip value
The value of the test for the slip resistance of the pendulum measured by a pendulum slip resistance tester.
3.5 Critical angle acceptanceangle
The maximum slope angle at which a person can walk safely on a slope without slipping.
4 rating
4.1
Static friction coefficient (dry) The classification of anti-skid grades is shown in Table 1.
