4、uts, rivets and similar fasteners was organized in March 1922, as Sectional Com,mittee 818, under the aegis of the American Engineering Standards Committee (later the American Standards Association, then the United States of America Standards Institute and, as of October 6, 1969, the American Nation

5、al Standards Institute, 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

6、at development of a standard covering solid rivets of less than 1/2 inch nominal diameter which was approved and designated 8 18a-1927. This was followed by a standard covering tinners, coop.ers and belt rivets that was adopted under the designation 8189-1928. Extensive research, periods of experime

7、ntation, and consultation 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 1/2 inch nominal size and larger. This pr

8、oposal, following approval by the Sectional Committee and sponsor organ- izations was designated an American Standard, 818.4-1937, 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

9、 up to date and, as necessary, develop them into complete product standards. A thorough study of the 818.4 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 chang

10、ed to conform with the 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 of the 818 Committee and sponsors, and presented

11、to the American Standards Association for approval and designa- tion as an American Standard. This was given on August 30, 1950. The 818 Committee by letter ballot of August13,1956 approved reaffirmation of the 818.4-1950 docu- ment and, following approval by the sponsors, this status was confirmed

12、by the American Standards 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 revis

13、ion incorporating changes 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 818 Committee and sponsor organizations, the revision was subm
