Significance and Use | ||||||||||||||||||
The g-max values obtained by these procedures are indicative of the impact attenuation characteristics of playing surfaces used for sports such as American football, soccer, baseball, lacrosse, rugby, etc. Optional time history data can be used to further describe these properties. |

1. Scope | ||||||||||||||||||
1.1 This test method is used to determine the impact-attenuation characteristics of natural turfgrass and soil playing surface systems with a lightweight portable apparatus. This test method can be used to compare the impact attenuation characteristics of natural playing surface systems, as well as assessing the effects of management practices on the impact attenuation characteristics. This test method also can be used to assess the compactibility of natural playing surfaces by recording g-max values or penetration of successive impacts, or both. 1.2 This test method provides a procedure for assessing impact attenuation characteristics in the field, on both actual playing surfaces and research plots. Numerical data will not be comparable to data obtained using a different missile mass or geometry, different drop height, or different standard method, for example, Test Method . 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 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. |
