Standard Test Methods for Measuring High Speed Baseball Bat Performance Factor
1.1 This specification defines a method for determining bat performance by measuring the bat-ball coefficient of restitution (BBCOR), deriving the bat performance factor (BPF), deriving the ball exit speed ratio (BESR), and calculating a batted-ball speed (BBS). It is applicable to baseball and softball bats of any construction or material. The method provides a quantitative measure of bat dynamic performance that may be used for comparison purposes.
1.2 The BBCOR, BPF, BESR, and BBS are each calculated from measurements taken in the laboratory on test equipment meeting the requirements defined in this specification.
1.3 The values stated in English units are to be regarded as the standard.
1.4 This standard does not purport to address all of the safety concerns, 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.
