14、chine 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 Automotive Engineers and the AmericanSociety of Mechanical Engineers as
15、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 opinion developed between the manufacturersand users of taper machine p
