(Test Method)Standard Test Method for Shock-Absorbing Properties of Playing Surface Systems and Materials
Standard Test Method for Shock-Absorbing Properties of Playing Surface Systems and Materials
SIGNIFICANCE AND USE
Dynamic data obtained by these procedures are indicative of the cushioning properties of the playing surface systems and materials under the specific conditions selected.
SCOPE
1.1 This test method covers the measurement of certain shock-absorbing characteristics, the impact force-time relationships, and the rebound properties of playing surface systems. This test method is applicable to natural and artificial playing surface systems and to components thereof. Typical playing surfaces are wrestling mats, football fields, soccer fields, playgrounds, and so forth.Note 1—This test method may also be used to measure the shock-attenuation properties of materials used as protective padding, such as the padding on trampoline frames, football goal posts, gymnasium wall, shoulder pads, body padding, and so forth. It should not be used, without some modifications, to test the finished products.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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.
