30、d substantively since GGG-G-15Bof 1970. During the intervening years there have been a number of very important shiftsin the use of gage blocks, a large growth of internationalization in design and manufactureof parts, and even changes to basic concepts like uncertainty and traceability. With all of
31、these factors in mind, the B89.1.9 Committee began to consider a total rewrite of thestandard in the early 1990s. Our basic criteria were to adhere to the International StandardISO 3650 as closely as possible, while making necessary additions to adapt the standardto measuring practice in the United
32、States.The most obvious additions were specifications for inch system gage blocks. We haveavoided the more traditional term “English” system because the metric system is the legalsystem of units in England. The International Standard also only defines rectangular gageblocks, the United States being
33、perhaps the only country to have square “Hoke” style blocksin significant numbers. Since the new grades have some of the same designations as theold standard we have added prefix “AS” to the names of Grades 1 and 2 to preventmisidentification. We have also added a Grade 00 with tolerances near those
34、 of the currentU.S. Grade 1. While the committee basically agreed with the logic behind the ISO 3650grade tolerances, we also recognized that the use of graded sets is deeply imbedded insome industries, and the loss of the high accuracy grade would be a hardship for some users.There are a large numb
35、er of appendixes to the standard. Most of these appendixes haveinformation that is not in the current ISO 3650, but was in GGG-G-15C or previous editionsof B89.1.9. The two largest and most important of these describe the differences betweenthis Standard and its predecessors in Nonmandatory Appendix
36、 B, and the definition andtolerances on gage block accessories in Nonmandatory Appendix H.The committee would also like to acknowledge the large number of people who, whilenot members of the committee, were kind enough to attend an occasional meeting or sendcomments on the early drafts of the standa
37、rd. These interactions increased the committeesknowledge of actual gage block use in industry, and were very important in drafting thechanges made to ISO 3650 to correspond to U.S. practice.This Standard was approved as an American National Standard on January 14, 2002.vASME STANDARDS COMMITTEE B89D

42、 developed and maintained with the intent torepresent the consensus of concerned interests. As such, users of this Standard may interactwith the Committee by requesting interpretations, proposing revisions, and attending Committeemeetings. Correspondence should be addressed to:Secretary, B89 Main Co
43、mmitteeThe American Society of Mechanical EngineersThree Park AvenueNew York, NY 10016-5990Proposed 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. Appro
44、ved revisions will be published periodically.The Committee welcomes proposals for revisions to this Standard. Such proposals shouldbe as specific as possible: citing the paragraph number(s), the proposed wording, and adetailed description of the reasons for the proposal, including any pertinent docu
45、mentation.Interpretations. Upon request, the B89 Committee will render an interpretation of anyrequirement of the standard. 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 unambigu
46、ous. It is further recommendedthat the inquirer submit his/her request in the following format:Subject: Cite the applicable paragraph number(s) and provide a concise description.Edition: Cite the applicable edition of the standard for which the interpretationis being requested.Question: Phrase the q
47、uestion as a request for an interpretation of a specificrequirement 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
48、, which may inadvertently change the intent of theoriginal request.ASME procedures provide for reconsideration of any interpretation when or if additionalinformation which might affect an interpretation is available. Further, persons aggrieved byan interpretation may appeal to the cognizant ASME com
49、mittee or subcommittee. ASMEdoes not approve, certify, rate, or endorse any item, construction, proprietarydevice, or activity.Attending Committee Meetings. The B89 Main Committee regularly holds meetings thatare open to the public. Persons wishing to attend any meeting should contact the Secretaryof the B89 Main Committee.viiIntentionally left blank ASME B89.1.9-2002GAGE BLOCKS0 INTRODUCTIONGage blocks are length standards representing specificfractions of the unit of length, the meter, of theinternational system of units
