12、ch 1926,when the Sectional Committee on the Standardization of Machine Pins wasorganized under the procedure of the American Standards Association(later the UnitedStates of America Standards Institute and as of October 6,1969,the American NationalStandards Institute,Inc.),with the Society of Automot
13、ive Engineers and the AmericanSociety of Mechanical Engineers as joint sponsors.For the next year or two,an effort was made via correspondence to develop a basis onwhich a standard for straight,taper,split,and dowel pins might be established.Throughthis correspondence a distinct difference of opinio
14、n developed between the manufacturersand users of taper machine pins,which seemed to discourage the members of the committeefrom attempting standardization on any of the types of pins within its scope.The sponsororganizations made frequent efforts to revive this project through letters and the distr
