Summary of Test 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 thedegre
22、e of force attenuation provided or caused by the surfacein certain movement situations. It is principally related to thegive of the surface upon impact. The higher the forcereduction, the greater the absorptive effect. The referenced testmethod is more closely associated with impacts generated bylow
23、er extremities and is not an indication of the 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
24、 activities. Ball rebound is anoptional consideration 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 Verti
25、cal DeformationTest Method F2157 provides anondestructive 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,
26、 while the inability of the surface todeform can 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 fie
27、ld testing.6.

When the system isdeemed to have a discernible difference in grain from onedirection to the other, each sample shall be tested in twodirections to be defined as with and across the grain.Across thegrain shall

If the results of all five individual readings inthe set are within the prescribed range, the inflation pressure iscorrect. If any of the individual readings within the set do notfall in the specified range, adjust air pressure in the ball andrepeat the set unt
