Details
1.1 A method for determining bat performance by measuring the bat-ball coefficient of restitution (BBCOR), deriving the collision efficiency (ea), and calculating a batted-ball speed (BBS). It is applicable to baseball and softball bats of any construction or material. The test methods provide quantitative measures of bat dynamic performance that may be used for comparison purposes.
1.2 The BBCOR and BBS are each calculated from measurements taken in the laboratory on test equipment meeting the requirements defined in this standard.
1.3 Bat performance is found in this standard assuming the bat is unconstrained.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 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.
1.6 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.
Significance and Use:
4.1 These test methods offer a laboratory means to quantitatively compare the performance of baseball and softball bats.
4.2 Use of these test methods can provide quantitative metrics of bat performance.
