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

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
