4、 fasteners was organized in March 1922, as Sectional Com,mittee B18, under the aegis of the American Engineering Standards Committee (later the American Standards Association, then the United States of America Standards lflstitute and, as of October 6, 1969, the American National Standards Institute
5、, Inc.) with the Society of Automotive Engineers and the American Society of Mechanical Engi- neers as joint sponsors. Subcommittee 1 was subsequently appointed and charged with responsibility for the standardization of rivets, Initial efforts of the Subcommittee were directed at development of a st
6、andard covering solid rivets of less than 1/2 inch nominal diameter which was approved and designated B 18a-1927. This was followed by a standard covering tinners, coop.ers and belt rivets that was adopted under the designation B18g-1928. Extensive research, periods of experimentation, and consultat
7、ion with the American Society for Testing and Materials and the Boiler Code Committee of the American Society of Mechanical Engineers during the ensuing years culminated in Subcommittee acceptance, in 1936, of a proposal covering rivets 112 inch nominal size and larger. This proposal, following appr
8、oval by the Sectional Committee and sponsor organ- izations was designated an American Standard, B18.4-1937, in March of 1937. Following reorganization of Sectional Committee 818, in 1947, Subcommittee 1 was requested to review the documents under its jurisdiction to bring them up to date and, as ne
9、cessary, develop them into complete product standards. A thorough study of the B18.4 standard was conducted over meetings of the Subcommittee held on October 9, 1947, June 4,1948 and December 1, 1948. This resulted in a recommen- dation that the pan head rivets should be changed to conform with the
10、American Bureau of Shipping and U. S. Navy design which all manufacturers, except one, were found to be producing. A proposal dated September 1959, reflecting this change and additional refinements was approved by letter ballot ofthe B18 Committee and sponsors, and presented to the American Standard
11、s Association for approval and designa- tion as an American Standard This was given on August 30, 1950. The B18 Committee by letter ballot of August13,1956 approved reaffirmation of the B18.4-1950 docu- ment and, following approval by the sponsors, this status was confirmed by the American Standards
12、 P Association on May 27, 1957. A proposed revision dated August, 1959 was approved by the Sectional Committee, the sponsors, and the American Standards Association and was designated an American Standard on March 9, 1960. During 1970, Subcommittee 1 developed a proposed revision incorporating chang
13、es to the nomenclature and the method of dimensioning applicable to countersunk type heads and a complete editorial revamping of the format to conform with related documents. Following letter ballot approval by the B18 Committee and sponsor organizations, the revision was submitted to the American N
14、ational Standards Institute and was designated an American National Standard, ANSI 818.1.2-1972, on January 28, 1972.
