Terminology3.1 Definitions:3.2 point-elastic, adjdescribes sports floors which areonly comprised of an
6、elastic layer or layers. (for example,surfaces such as poured urethanes, vinyl or rubber sheetgoods).3.3 combination-elastic, adjdescribes sports floors havinga point elastic upper layer in combination with a rigid structurallayer (for example, wood, high density composites, pourednon-resilient mate
7、rials) and resilient support components (forexample, elastic pads, foam blanket or poured urethane).3.4 area-elastic, adjdescribes sports floors having a rigidupper layer (for example, wood) supported by resilient com-ponents.4. Summary of Test Methods4.1 Force ReductionTest Method F2569 provides a
8、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 surfacein certain movement situations. It is principally
9、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 ability of thetest surface to prevent head trauma.4.2 Ba
10、ll ReboundEN 12235/C1 provides a non-destructive means that can be used both in the laboratory andin the field by which to identify the ball rebound height ofvarious balls used for indoor sports activities. Ball Rebound isan optional consideration for certain activities commonlyassociated with indoo
11、r 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. Specimen Preparation5.1 Testing in the laboratory shall be performed at atemperature of 23 6 2C (73 +4/3F) unless

The test specimenshall be placed over a substrate typically required by themanufacturer. Non-free floating floors shall be soundly

24、all inflation may bedetermined by using either timed duration, or computed orvisual rebound height.7.2.2.1 When using timed duration, proper inflation requiresthat each reading results in a value between 0.938 and 0.960 sinclusive.7.2.2.2 When using computed or visual height, properinflation require
25、s that each reading results in a value to thebottom of the ball between 1.03 and 1.08 m (40.5 and 42.5 in.)inclusive.7.2.2.3 Perform a set of five repetitive drops on a rigidconcrete surface recording the readings between the first andsecond impacts. If the results of all five individual readings in
26、the 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 until all five readings in the set comply.8.
