Phạm vi áp dụng / Scope of standard

3.1 This test method offers a means to compare the barrel compression of softball and baseball bats. This test is not intended for wood or solid bats.

1.1 This test method describes a comparative measurement method for determining the compression force of softball and baseball bat barrels as defined by a static compression displacement test.

1.2 This standard is not intended to define the performance of softball or baseball bats but to determine the intrinsic barrel compression of a specific bat.

1.3 This standard can be used to compare the relative barrel compression force of bats using a relatively slow, non-impact loading rate.

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 and health practices and determine the applicability of regulatory limitations prior to use.
