1.1本规范定义了一种通过测量蝙蝠球恢复系数（BBCOR）、推导蝙蝠性能系数（BPF）、推导出球出口速度比（BESR）和计算击球速度（BBS）来确定蝙蝠性能的方法。它适用于任何结构或材料的棒球和垒球球棒。该方法提供了bat动态性能的定量测量，可用于比较目的。 1.2 BBCOR、BPF、BESR和BBS均根据实验室在满足本规范规定要求的测试设备上进行的测量进行计算。 1.3以英制单位表示的数值应视为标准。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

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.
