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 and health practices and determine the applicability of regulatory limitations prior to use.
