Explanations: 1) Opening against the previous default of Ril. 820,2120, 3 (1): "For complete tracks, rails usually in lengths > 100 m to deliver on the site." The values below "d" are to be observed in the entire range of 3 m in front and behind the weld! 2) News of rail ends and weld joint in the production with the following requirements: vertical flatness*: horizontal flatness*: d ≤ 0,4 mm at L = 3.0 m and d ≤ 0.3 mm at L = 1.0 m d ≤ 0,6 mm at L = 1.5 m
3) News of rail ends and weld joint in the production with the following requirements: vertical flatness*: horizontal flatness*: d ≤ 0,3 mm at L = 3.0 m and d ≤ 0.2 mm at L = 1.0 m d ≤ 0,45 mm at L = 1.5 m
4) News of rail ends and weld joint in the production with the following requirements on the construction site: vertical flatness*: horizontal flatness*: (5) RA = Flash butt welding (6) AS = aluminothermy welds * matched to the design CEN - Standard Pr 13674-1 Table 9 Significant changes d ≤ 0,4 mm at L = 3.0 m and d ≤ 0.3 mm at L = 1.0 m d ≤ 0,6 mm at L = 1.5 m
