12、andards Committee B89 on Dimensional Metrology, under procedures approvedby the American National Standards Institute (ANSI), prepares standards that encompasstheinspectionandthemeansofmeasuringcharacteristicsofsuchvariousgeometricparametersas diameter,length, flatness parallelism, concentricity, an
13、dsquareness. Becausedial indicatorsare widely used for the measurement and comparison of some of these features, the chairof the B89.1 Main Committee on Length authorized formation of Working Group B89.1.10to prepare this Standard.Most dial indicators used in the U.S. are built to inch measure speci
14、fications butInternational Organization for Standardization (ISO) standards do not address all the needsof U.S. industry. The inch measure portion of this Standard is strongly influence byCommercial Standard CS(E) 119-45, effective January 1, 1945, which was prepared by theAmerican Gage Design Commi
15、ttee (from which the term AGD Standard is derived), anddistributed by the Department of Commerce. It is also based in part on Commercial ItemDescription A-A-2348B, dated July 30, 1991, developed by the General Services Administra-tion (GSA). It is also based on manufacturers current practices and te
16、chnologies. Themetric measure portion of this Standard is based primarily on ISO efforts in support ofinternational commerce.Working Group B89.1.10 wishes to acknowledge the leadership of its chair, BruceRobertson, whose untimely passing has prevented him from seeing the end result of hiscontributio
17、ns to the work of this group.This Standard was approved by ANSI on April 10, 2001.ivASME STANDARDS COMMITTEE B89Dimensional Metrology(The following is the roster of the Committee at the time of approval of this Standard.)OFFICERSR.

22、n CommitteeThe American Society of Mechanical EngineersThree Park AvenueNew York, NY 10016Proposed Revisions. Revisions are made periodically to the standard to incorporate changesthat appear necessary or desirable, as demonstrated by the experience gained from theapplication of the standard. Approv

Interpretations can only be rendered in response to a writtenrequest sent to the Secretary of the B89 Main Committee.The request for interpretation should be clear and unambiguou
25、s. It is further recommendedthat the inquirer submit his/her request in the following format:Subject: Citetheapplicableparagraphnumber(s)andprovideaconcisedescription.Edition: Cite the applicable edition of the standard for which the interpretationis being requested.Question: Phrase the question as
26、a request for an interpretation of a specifcrequirement suitable for general understanding and use, not as a requestfor an approval of a proprietary design or situation.Requests that are not in this format may be rewritten in the appropriate format by theCommittee prior to being answered, which may
