4、 by Technical Committee Eindimensionale Lngenprftechnik of theNormenausschuss Technische Grundlagen (Fundamentals in Technology Standards Committee), takinginto account the specifications of DIN EN ISO 1119.AmendmentsThis standard differs from the October 2000 edition in that it has been editorially
5、 revised and now coversonly those specifications not dealt with in DIN EN ISO 1119.Previous editionsDIN 254: 1922-01, 1939-12, 1957-10, 1962-07, 1974-06, 2000-10.IntroductionThe term rate of taper has been introduced to denote the geometric expression for the difference in thediameters of two cone s
6、ections over the distance between these sections, D d/L, and to distinguish it fromthe term cone denoting a geometric body. Previously, the term cone was used in both cases.1 ScopeThis standard gives a series of cones or conical tapers intended for general use in mechanical engineering.It also speci
7、fies values for the half cone angle and setting height of the cones covered in DIN EN ISO 1119.Cones for particular applications are given in Annex A.This standard, together withDIN EN ISO 1119, April 2003edition, supersedes October2000 edition.Page 2DIN 254 : 2003-042 Normative referencesThis stand
