Standard Test Method for Measuring the Coefficient of Restitution (COR) of Baseballs and Softballs

Importancia y uso:

5.1 The ball coefficient of restitution is a ball dynamic property of relative velocity change caused by impact with a rigid wall.

5.2 This test method is suitable for obtaining data in research and development, quality control, and classifying balls by liveliness.

5.3 Sports associations can use coefficient of restitution standards in specifications for official baseballs and softballs.

5.4 This same test procedure can be utilized at impact speeds other then that prescribed in this procedure and so noted in any reported test results.
