Standard Test Method for Measuring Baseball Bat Performance Factor (Withdrawn 2014)
| 분야 | 15.07 : 스포츠 장비와 시설, 보행자 보도 안전과 신발 안전, 놀이 기구 |
|---|---|
| 적용범위 | 1.1 This test method defines a method for determining bat performance by measuring the bat-ball coefficient of restitution (BBCOR), deriving the bat performance factor (BPF), and calculating batted-ball speed (BBS). It is applicable to baseball bats of any construction or material. The test method provides a quantitative measure of bat dynamic performance that may be used for comparison purposes. 1.2 The BBCOR, BPF, and BBS are each calculated from measurements taken in the laboratory on test equipment meeting the requirements defined in this test method. 1.3 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. 1.4 This standard does not purport to address all 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 to determine the applicability of regulatory limitations prior to use. |
