29、license from IHS-,-,-FOREWORD (This Foreword is not part of ASME 818.8.1-1994.) The need for a standard covering machine pins was recognized by industry as far back as March, 1926, when the Sectional Committee on the Standardization of Machine Pins was organized under the procedure of the American S
30、tandards Association (later the United States of America Standards Institute and as of October 6, 1969, the American National Standards Institute, Inc.), with the Society of Automotive Engineers and the American Society of Mechanical Engineers as joint sponsors. For the next year or two, an effort w
31、as made via correspondence to develop a basis on which a standard for straight, taper, split, and dowel pins might be established. This correspondence developed a distinct difference of opinion on the part of ,the manufac- turers and users of taper machine pins, which fact seemed to discourage the m
32、embers of the committee from attempting standardization on any of the types of pins within its scope. The sponsor organizations made frequent efforts to revive this project through letters and the distribution of technical literature on this general subject, without avail. In December, 1941, in its
33、periodic review of standards projects for which the Society is sponsor, the ASME Standardization Committee decided that there was little hope for reviving this project and voted, subject to acceptance by the sponsors, to suggest to the ASA the transfer of this project to Sectional Committee B5 on th
34、e Standardization of Small Tools and Machine Tool Elements. The sponsors agreed and on July 7, 1942, the ASA santioned this action and Sectional Committee B43 was discharged and the project was officially transferred to Section Committee B5. At its meeting in December, 1942, Sectional Committee B5 v
35、oted to enlarge its scope to include machine pins. Technical Committee No. 23 was subsequently established and charged with the responsibility for technical content of standards covering machine pins. This group held its first meeting on November 30, 1943, at which time a Subgroup on Correlation and
36、 Recommendations was appointed and it was voted to include clevis pins in addition to the other pin types already under consideration. Several drafts were pre- pared by the subgroup, distributed for critical comment to users, manufacturers, and general interests, and revised and resubmitted for comm
37、ents. This action finally resulted in acceptance by Techinical Committee 23 of a draft dated November, 1945, which was duplicated in printers proof form, under a date of October, 1946, and distributed to the members of Sectional Committee B5 for letter ballot approval. Subsequent to the ap- proval o
38、f the Sectional Committee, the proposal was next approved by the sponsor bodies, and presented to the American Standards Association for approval as an American Standard. This designation was granted on July 7, 1947. Following the issuance of the standard, it became apparent that the table on cotter
39、 pins needed revision. Accordingly, in 1953 a proposed revision was submitted to the Sectional Committee. After attaining Sectional Committee and sponsor approval, this revision was approved by the American Standards Association on July 9, 1954 as ASA iii B5.20-1954. Copyright ASME International Pro
40、vided by IHS under license with ASMENot for ResaleNo reproduction or networking permitted without license from IHS-,-,-ASME BLB.Be3 94 m 0759670 0543439 696 W In 1956 and 1957, in response to requests from industry, extensive changes were in- corporated into a proposed revision. These included revis
41、ions to chamfer values and tolerances on straight pins and unhardened ground dowel pins; revisons to under head to hole, pin end dimensions, and hole size tolerances on clevis pins; addition of chisel point to cotter pin end styles and the incorporaton of coverage on grooved pins. Following Sectiona
42、l Committee and sponsor approvals, this revision was adopted by the American Standards Association on March 25, 1958, as ASA B5.20-1958. Later in 1961, Sectional Committee B5 suggested that Sectional Committee B18 on the standardization of bolts, nuts, rivets, screws, and similar fasteners assume ju
43、risdiction over standards forpins. Recognizing that the bulk of the products covered in the ASA B5.20 standards were fastener rather that machine oriented, this recommendation was supported by the B18 Committee and officially endorsed by the sponsor organizations. Consequently, at the September 14,1
44、962 meeting of this Committee it was decreed that Subcommittee 23l should be formed to undertake a review and updating of the pin standard. At the initial meeting of Subcommittee 23 held on June 3,1964, it was decided to add standards for spring pins (inch series) and to establish seven subgroups, e
45、ach of which would have technical responsiblity for specific pin products, and to publish respective products under separate cover as projects were completed. Over the ensuing four years, work by Subgroups 1 and 7 culminated in the development of a proposal for revision of the standards for clevis p
46、ins and cotter pins which was approved by letter ballot of Subcommittee 8 on June 19,1969. Subsequent to acceptance by American National Standards Committee B18 and the sponsor organizations, this document was duly submitted to the American National Standards Institute for approval as an American Na
47、tional Standard. This was granted on May 10,1972 and the standard was published under the designation ANSI B18.8.1, superseding in part the coverage provided in ASA B5.20-1958. Subcommittee 8 proposed revisions to the 1972 edition on July 23,1988. After several Main Committee ballots and reviews, th
48、e final proposal was submitted to the Board on Standardization which approved the standard on November 19, 1993. The standard was later approved by ANSI on April 5, 1994. As of April 1, 1966 Subcommittee 23 was redesignated Subcommittee B. iv Copyright ASME International Provided by IHS under licens
