Track materials Rails Differences UIC-K 860 E - DIN EN 13674-1 Page: 211-03 Difference between UIC-Kodex 860 E and DIN EN 13674-1:2008-01 The European Standard 13674-1 • includes the following qualification tests for steel rails: - Fracture toughness (KIc), Paragraph 8.2 - Assessment of crack growth rate, Paragraph 8.3 - Dynamic fatigue test, Paragraph 8.4 - Determination of the residual stresses in the rail foot, Paragraph 8.5 - Profile of the surface hardness on the runway at HH - rails, Paragraph 8.6 - Determination of tensile strength and elongation using a regression formula, Paragraph 8.7 • • • • • • • • • • • • • • • regulates the hydrogen and oxygen content and also the accompanying elements such as amongst Al, V, N, Cu, Sn etc.- Table 4, Paragraph 9.1.2 regulates surface decarburisation - Table 4, Paragraph 9.1.4 regulates efficiency of the rails - Table 4, Paragraph 9.1.5 contains sulphur prints, Paragraph 9.1.6 (Appendix D) allows tensile test only once every 2000 t under the condition of a regression formula refer to the rails after the minimum hardness, such as R260, instead of its minimum strength, such as 9000A according to UIC-Kodex 860 E refer the new rail sections (60E1 instead UIC 60), Appendix A, Page 43 includes the profile drawings (which were earlier included in UIC 861) allows two profile classes (X,Y) and two straightness classes (A,B) and on the contrary defines UIC-Kodex 860 E also the straightness between the ends, paragraph 9.2 defines the criteria for testing gauge as well as the methods of measurement, Paragraph 9.3 defines the test criteria for Us-audit, Paragraph 9.4.1 specifies criteria/tolerances and surface finish, paragraph 9.4.2 regulates the procedure for interoperability EU-Directives, Paragraph ZA is a pure material and testing standards no more includes the impact test (see Paragraph 2.6, UIC-Kodex 860 E) Without scale/schematic diagram Date of issue 08/10
