6、.S.A.ii FOREWORD American National Standards Committee 818 for the standardization of bolts,screws,nuts,rivets and similar fasteners was organized in March 1922,as Sectional Committee B18,under the aegis of the American Engineering Standards Committee(later the American Standards Association,then th
7、e 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 Engi-neers as joint sponsors.Subcommittee 1 was subsequently appointed and charged with responsibilit
8、y for the standardization of rivets.Initial efforts of the Subcommittee were directed at development of a standard covering solid rivets of less than 1/2 inch nominal diameter which was approved in 1927 and designated B18a-1927.A proposed standard covering tinners,coopers and belt rivets was granted
9、 recognition as a tentative document in May of 1928 and was approved as an American Standard in January 1929 under the designa-tion B 189-1928.Revisions made to both of these standards relative to physical tests were issued as addendums under the designations B18al-1942 and B18g1-1942,respectively.F
10、ollowing 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 necessary,develop them into complete product standards.Revisions to the documents on small rivets,and tinners,coopers,and belt rivets
11、 were considered at length during several meetings of the Subcommittee held over a period from 1947 to 1951.A draft proposal combining the data contained in both prior documents under the common heading Small Solid Rivets,incorporating dimensional tolerances with no significant change in basic dimen
12、sions was agreed upon by the Subcommittee in November 1952.Following approval by letter ballot of the Sectional Committee and sponsor organizations the revision was submitted to the American Stan-dards Association and was designated an American Standard,B18.1-1953,in June of 1953.Shortly after publi
13、cation of the 1953 standard,Subcommittee 1 undertook development of a revision to include data for chamfered points and other minor refinements to meet requirements of the user industry.The resulting proposal was approved by letter ballot of the 818 Committee conducted on May 10,1954.Subsequent to a
14、pproval by the sponsors,the revision was presented to the American Standards Association for designation as an American Standard.This was granted on October 5,1955.From 1960 to 1962,a number of changes to the standard relating to underhead fillets,dimensioning of countersunk head rivets,points,and m
15、aterial specifications were approved by the Subcommittee.A draft proposal incorporating these revisions and numerous editorial corrections was approved by letter ballot of the Sectional Committee on February 11,1964.Following approval by the sponsor organizations the revision was designated an Ameri
16、can Standard on September 20,1965.During 1969 and 1970,Subcommittee 1 drafted a revision of the 818.1 Standard incorporating the addition of the 60-degree flat countersunk head(formerly on Standard ASAE S228),changes to nomen-clature for countersunk head and truss head rivets,and a complete reworking of the format to conform with related documents.Subsequent to letter ballot approval by American National Standards Committee B18 and the sponsors,the revision was submitted to the American National
