No localised bumps greater than 6mm below 4 m straight edge, 3 mm below 1 m edge.
1.3 Surface thickness
Surface shall be at least 12 mm - nowhere less than 10 mm
1.4 Force Reduction
Berlin Athlete value must be greater than 35 %
1.5 Modified Vertical Deformation
Stuttgart Athlete value must lie between 0.6 and 1.8 mm
Must be greater than 0.5 wet as measured by the BTRRL friction tester .
1.7 Tensile Properties
Minimun tensile strengths: Porous 0.4 MPa, Non-Porous 0.5 MPa
Uniform to one position of the Methuen Handbook of Colour
Must drain of excess water in less than 20 min.
