ASTM F1702-96 - 1.1.1996
 
1. Scope

1.1 This test method covers the determination of shock-attenuation characteristics of natural turf grass and soil playing surface systems using lightweight portable apparatus. This test method is applicable for comparing natural surfaces and for assessing the effects of management practices on shock attenuation. This test method also can be used to assess the compatibility of natural surfaces by recording G max values or penetration of successive impacts, or both.

1.2 This test method provides a procedure for assessing impact characteristics in the field, on actual playing surfaces and on research plots. Numerical data will not be comparable to data obtained using a different missile mass or geometry, using a different drop height, or using a different standard method, for example, Test Method F 355.

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 may involve hazardous materials, operations and equipment. 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.
