1. Scope | ||||||
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. |
