Summary of Te
21、st Methods5.1 Force ReductionTest Method F2569 provides a non-destructive means for evaluating the force reduction propertiesof the surface in both laboratory and field settings. Forcereduction is a characteristic of sports surfaces indicating thedegree of force attenuation provided or caused by the
22、 surfacein certain movement situations. It is principally related to thegive of the surface upon impact. The higher the force reduc-tion, the greater the absorptive effect. The referenced testmethod is more closely associated with impacts generated bylower extremities and is not an indication of the
23、 ability of thetest surface to prevent head trauma.5.2 Ball ReboundTest Method F2117 provides a nonde-structive means that can be used both in the laboratory and thefield by which to identify the ball rebound height of variousballs used for indoor sports activities. Ball rebound is anoptional consid
24、eration for certain activities commonly associ-ated with indoor sports surfaces. Ball rebound values onparticular surfaces indicate whether those floors provide suit-able or desired values in relation to the preferred activity in thesports hall.5.3 Vertical DeformationTest Method F2157 provides anon
25、destructive means that can be used both in the laboratoryand the field by which to identify vertical deformation as theability of the surface to deform under load. Too high adeformation can affect the safety of the athlete throughinstability of the foot, while the inability of the surface todeform c
26、an cause injuries as a result of impact forces.5.4 Surface Finish EffectTest Method E303 provides anondestructive test for determining the surface finish effectusing the British pendulum skid resistance tester. This tester issuited for laboratory and field testing.6. Dimensions, Mass, and Permissibl
