Значение и использование

This test method offers a laboratory means to measure the inertial properties of bats, specifically weight, balance point, center of percussion, and MOI, in support of other test methods including the ASTM standards referenced in this document.

Use of this test method can provide sports governing bodies the means to establish rules regarding the physical properties of bats, specifically MOI.

Область применения

1.1 This test method covers a method for determining the moment of inertia (MOI) and balance point (BP) of baseball and softball bats. These physical properties are used in calculations in other key ASTM standards.

1.2 The MOI and BP are measured 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 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.
