ASTM F2569-11(2019)

5.1 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.

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

5.3 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.

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

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.

1.3 The test methods described are applicable in both laboratory and field settings.

1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
