1. Scope
1.1 This procedure is intended to standardize a method of measuring the dynamic stiffness (DS) of baseballs and softballs.
1.2 This procedure is established to provide a single, repeatable, and uniform test method.
1.3 This procedure is for a ball that is intended for use inthe game of baseball or softball.
1.4 The test method is based on ball speed measurements before and after impact with a cylindrical test surface and the impact force between the ball and impacted surface.
1.5 This standard does not purport to address all of the safety concersn, 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.
