Rail length and other geometric dimensions and tolerances, etc., from the "8" in the corresponding light and heavy rail standards.
(1) After rolling the rail should be straight, no significant bending and torsion. For the light and heavy rail local bending and torsion and its correction of deformation, the track end of the tilt, etc., shall not exceed the standard requirements.
(2) rail surface should be clean and smooth, shall not have cracks, scarring, scratches and other defects; the end surface may not have shrinkage traces and sandwich. For light rails the overall surface allow the existence of defects and the extent of its geometric volume, shall not exceed the standard requirements.
