Scope

The force reduction property is just one of the important properties of a surface used for athletic activity. It may be an indicator of the performance, safety, comfort, or suitability of the surface.

Manufacturers of athletic surfaces may use this test method to evaluate the effects of design changes on the impact forces generated on the surface.

Facility owners may use this standard to evaluate the performance of existing sport/athletic surfaces. Results may be useful during the selection process for a replacement surface, or for an additional athletic surface being added to the facility.

Facility owners may also use this test method to verify that newly installed surfaces perform at or near the levels included in project specifications.

FIG. 1 Force Reduction Test Apparatus

1.1 This test method covers the quantitative measurement and normalization of impact forces generated through a mechanical impact test on an athletic surface. The impact forces simulated in this test method are intended to represent those produced by lower extremities of an athlete during landing events on sport or athletic surfaces.

1.2 This test method may be applied to any surface where athletic activity may be conducted.
