ScopeThis European Standard specifies a method for determining the anti-slip characteristics of the base of sports matstypes 1 to 8 of EN 12503-1:2001 or type 12 of EN 12503-3:2001.2
Normative referencesThis Europen Standard incorporates, by dated or undated reference, provisions from other publications.

PrincipleThe mass of the mat is determined together with the slip resistance characteristics of the base of the mat. This ismeasured by an aluminium foot (slider) attached to the arm of a pendulum, which is allowed to slide over the basefor a set distance and the energy absorbed by friction measured.4
Apparatus4.1
Friction tester4.1.1
The friction tester shall be in accordance with figure 1 and comprise of the following:a) a spring loaded slider of the mass, size and shape specified in 4.1.3 mounted on the end of a pendulum (see4.1.2) so that the sliding edge is approximately 510 mm from the axis of suspension;b) means for setting the column of the instrument vertical;c) means for raising and lowering the axis of suspension of the pendulum so that the slider can1) swing clear of the surface of the test piece, and2) be set to slide over a fixed length of surface of 126,0 mm. This length should be as near as is visuallypossible but in any case within ± 1 mm;d) means for holding and releasing the pendulum;e) a pointer balanced about the axis of suspension, indicating the position of the pendulum throughout its forwardswing and moving over the circular scale drawn as specified in 4.2. The mass of the pointer shall be not
