Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope
3、1.1 This specification covers requirements for ferrous and nonferrous inch balls. The balls covered in this specification areintended for use in bearings, bearing applications, check valves, and other components using balls.1.2 This is a general specification. The individual item requirements shall
4、be as specified herein in accordance with the AnnexA2 through Annex A9MS sheet standards. In the event of any conflict between requirements of this specification and the AnnexA2 through Annex A9MS sheet standards, the latter shall govern.1.3 The values stated in inch-pound units are to be regarded a
5、s standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information only and are not considered standard.1.4 This specification contains many of the requirements of MIL-B-1083, which was originally developed by the Departmentof Defense and maintained
