1、 AN AMERICAN NATIONAL STANDARD Gages and Gaging for Unified Inch Screw Threads ANWASME B1.Z1983 (REVISION OF ANSI B1.2-1974) SPONSORED AND PUBLISHED BY THE AMERICAN SOCIETY OF MECHANICAL ENGINEERS United Engineering Center 345 East 47th Street New York, N. Y. 10017 This Standard will be revised when

2、 the Society approves the issuance of a new edition. There will be no addenda or written interpretations of the requirements of this Standard issued to this Edition. Date of Issuance: June 15, 1984 This code or standard was developed under procedures accredited as meeting the criteria for Ameri- can

3、 National Standards. The Consensus Committee that approved the code or standard was balanced to assure that individuals from competent and concerned interests have had an opportunity to partici- pate. The proposed code or standard was made available for public review and comment which pro- vides an

FOREWORD (This Foreword is not part of American National Standard ANSVASME 61.2-l 983, Gages and Gaging for Unified Inch Screw Threads.) American National Standards Committee Bl for the Standardization of screw threads was org

9、anized in 1920 as Sectional Committee Bl under the aegis of the American Engi- neering Standards Committee (later the American National Standards Association, then the United States of America Standards Institute and, as of October 6, 1969, the American National Standards Institute, Inc.), with the

10、Society of Automotive Engineers and the American Society of Mechanical Engineers as joint sponsors. In 1982, American National Standards Committee Bl was reorganized as the ASME Standards Committee Bl, and since then it has operated under the American Society of Mechanical Engineers Procedures to pr

11、oduce and update standards which may become ANSI Standards after final approval by the American National Standards Institute. A declaration of accord with respect to the unification of screw threads was signed on November 18, 1948, by representatives of the services and industry of the United States

12、, the United Kingdom, and Canada. The ANSI Unified Screw Thread Standard B 1.1, through the quadripartite standardization agreement (QST AC) 247, Unified Threads, is subject to an international standardization agreement through the instrumentality of the American- British-Canadian-Australian Army St

13、andardization Program, which recognizes B 1.1 as a standard for Unified Threads when it is required to effect the interchangeability of parts and equipment between the armies of the participating nations. The first American National Standard for Screw Thread Gages and Gaging was pub- lished as ASA B

14、 1.2- 194 1 to supplement the parent Standard AS A B 1. l- 1935, Screw Threads for Bolts, Nuts, Machine Screws and Threaded Parts. That Standard was revised and re- published as a Unified Standard ASA Bl.l-1949 and again as ASA Bl.l-1960. The Uni- fled Gage Standard was republished as ASA B1.2-1951

15、and USA B1.2-1966. On February 9, 1973, a meeting was held by the Department of Commerce at the Na- tional Bureau of Standards, Washington, D.C., attended by representatives of government and industry screw thread interests. With the goal of eliminating parallel standards, those at the meeting recom

16、mended that the NBS Handbook H-28 be converted into a coordinat- ing document for government screw thread standards wherein sections of H-28 would be replaced by single page references to existing industry standards. It was further recom- mended that the chairman of American National Standards Commi

17、ttee B I set up a group to clearly define and establish identified levels of acceptability for screw threads. At an American National Standards Committee Bl meeting held on May 3, 1973, unani- mous approval was given to the following motion: “The Bl Committee recognizing the needs of industry for di

18、fferent levels of acceptability for screw threads, establishes new scopes for Standards B 1.1 and B 1.2 and sets up a new standard, B 1.3.” References to con- formance criteria were removed from ANSI B1.2-1974 and additional gages and gaging data were added to suit additional conformance requirement

19、s specified in ANSI B1.3 or other Bl thread documents. This new publication, designated ANSI/ASME B1.2-1983, has had considerable new material added to cover the many options of gages and measuring equipment shown in ANSI B 1.3, Screw Thread Gaging Systems for Dimensional Acceptability. It has also

20、re- . . . 111 applied HI and LO to function as NOT GO gages and has eliminated gages with pitch di- ameter outside product thread limits. ANSl B1.2 was approved by the ASME Standards Committee Bl on March 18, 1983. The proposed standard was submitted by the ASME Board of Standardization to the Ameri

21、can National Standards Institute. It was approved and formally designated an American National Standard on May 16, 1983.
