Significance and Use
4.1 These test methods offer a laboratory means to quantitatively compare the performance of softball and baseball bats.
1.1 A method for determining bat performance by measuring the bat-ball coefficient of restitution (BBCOR) and deriving the bat performance factor (BPF). It is applicable to softball and baseball 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 and BPF are calculated from measurements taken in the laboratory on test equipment meeting the requirements defined in this method.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are units that are provided for information only and are not considered 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
