EN 13674-1 Standard: Vignole Railway Rails (46 kg/m and above)
This part of the international standard establishes strict technical requirements for the production and performance characteristics of Vignole rails weighing 46 kg/m and above. Products supplied by EV Group China fully comply with these standards to ensure safety on public tracks and high-speed railways.
Technical specifications cover nine grades of pearlitic steel with a hardness range from 200 HBW to 440 HBW. The range includes both non-alloy and alloy steels, which may or may not be heat-treated to improve mechanical properties.
The standard regulates 23 rail profiles and defines two classes of straightness, as well as requirements for surface geometry and rail head profile accuracy.
EN 13674-2 Standard: Rails for Switches and Crossings
This section of the EN 13674 specification defines the parameters for rail products intended for integration into switches and crossings used in conjunction with Vignole-type rails (from 46 kg/m). It is important to note that the standard does not apply to check rails that do not bear wheel loads.
For the production of these elements, EV Group China uses eight grades of pearlitic steels with a hardness range of 200–390 HBW. The standard covers 34 profiles that ensure high wear resistance in areas of increased dynamic loads.
EN 13674-3 Standard: Check Rail Profiles
This part of the standard focuses on technical requirements and materials for specialized check rails. The regulation does not cover guard rails for bridge structures or viaducts. The current nomenclature includes five profiles manufactured from three steel grades, optimized for specific control tasks.
EN 13674-4 Standard: Light Vignole Rails (from 27 to 46 kg/m)
This standard describes the characteristics of flat-bottomed railway rails (Vignole type) with a linear mass from 27 kg/m to 46 kg/m (excluding 46 kg/m). The products meet high reliability requirements for access roads and industrial lines.
To ensure regulated hardness indicators (200–390 HBW), five grades of pearlitic steel are used. The standard describes 13 profiles, the availability of which can be confirmed upon ordering from EV Group China.
