1 Scope
This Technical Specification specifies a method of test for measuring the shock absorption, vertical
deformation, and energy restitution characteristics of sports surfaces. It is not considered appropriate for rigid
sports surfaces that have shock absorbing properties of 10 % FR (Force reduction) or less.

3 Terms, definitions and symbols
3.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1.1
shock absorption (SA)
ability of a sports surface to reduce the impact force of a body falling onto the surface
Note 1 to entry: This reduction in impact force is expressed as a percentage reduction in force (Force Reduction)
when compared to a reference force of 6760 N, which is the theoretical maximum impact force that could occur when the
test is undertaken on a rigid non shock absorbing surface (e.g.) concrete.
3.1.2
deformation (D)
measure of how far a test foot compresses or penetrates into the surface when a standard impact force is
applied
3.1.3
energy restitution (ER)
measure of the energy returned by the sports surface after the impact force has been applied
3.1.4
energy restitution coefficient
ratio of the dynamic load energy applied to the surface to the energy returned by the surface (R)
3.1.5
sports surface
