    1、Designation: B23 00 (Reapproved 2014)Standard Specification forWhite Metal Bearing Alloys(Known Commercially as “Babbitt Metal”)1This standard is issued under the fixed designation B23; the number immediately following the designation indicates the year of originaladoption or, in the case of revisio

    2、n, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscriptepsilon () 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. Scope1.1 This specificatio

    3、n covers eight typical white metalbearing alloys, in bar or ingot form, known commercially as“babbitt metal.” The alloys are specified, covering the rangecommercially used, and are designated by the alloy numbersshown in Table 1.1.2 The values stated in inch-pound units are to be regardedas standard

    4、. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standa

    5、rd to become familiarwith all hazards including those identified in the appropriateMaterial Safety Data Sheet (MSDS) for this product/materialas provided by the manufacturer, to establish appropriatesafety and health practices, and determine the applicability ofregulatory limitations prior to use.2.
