FOREWORD
The United States gage block standard has not changed substantively since GGG-G-15B of 197 1970. 0. Dur During ing the interve intervenin ning g years years there there have have been been a num number ber of ver very y imp import ortant ant shift shiftss in the use of gage blocks, a large growth of internationalization in design and manufacture of parts, parts, and even even change changess to basic basic concep concepts ts like like unc uncert ertain ainty ty and trace traceabi ability lity.. With With all of th thes esee fact factor orss in min mind, d, th thee B89. B89.1. 1.9 9 Co Comm mmitt ittee ee be bega gan n to cons consid ider er a tota totall re rewr writ itee of the the standard in the early 1990s. Our basic criteria were to adhere to the International Standard ISO 365 3650 0 as clo closel sely y as possib possible, le, whi while le mak making ing necess necessary ary additio additions ns to ada adapt pt the standa standard rd to measur measuring ing practi practice ce in the Uni United ted States States.. The most most obv obviou iouss additio additions ns wer weree spe specifi cificat cation ionss for inch inch sys system tem gag gagee blocks blocks.. We have have avoided the more traditional term “English” system because the metric system is the legal system syste m of units in Engla England. nd. The Internatio International nal Stand Standard ard also only defines rectangu rectangular lar gage blocks, the United States being perhaps the only country to have square “Hoke” style blocks in signifi significan cantt num number bers. s.

We have also added a Grade 00 with tolerances near those of the current U.S.. Gra U.S Grade de 1. Wh While ile the commi committe tteee bas basica ically lly agreed agreed with the logic beh behind ind the ISO 365 3650 0 grade gra de tole toleran rances ces,, we als also o recogn recognize ized d tha thatt the use of gra graded ded sets is dee deeply ply imbedd imbedded ed in some industries, and the loss of the high accuracy grade would be a hardship for some users. There are a large number of appendixes to the standard. Most of these appendixes have information that is not in the current ISO 3650, but was in GGG-G-15C or previous editions of B89.1. B89.1.9. 9. The two lar larges gestt and most most imp import ortant ant of these these descri describe be the differ differenc ences es betwee between n this this Standa Standard rd and its predec predecess essors ors in Nonman Nonmandat datory ory Append Appendix ix B, and the defi definiti nition on and tolerances toler ances on gage block acce accessor ssories ies in Nonmandato Nonmandatory ry Appen Appendix dix H. The committee committee would als also o like like to acknow acknowled ledge ge the large number number of peo people ple who, whi while le not members of the committee, were kind enough to attend an occasional meeting or send comments on the early drafts of the standard. These interactions increased the committee’s knowle kno wledge dge of actual actual gage block block use in indust industry, ry, and wer weree ver very y imp import ortant ant in dra drafti fting ng the change cha ngess made made to ISO 365 3650 0 to corres correspon pond d to U.S. U.S. pra practic ctice. e.
