EN 14535 – Part 2: Brake Discs Mounted onto the Wheel, Dimensions, and Quality Requirements Standard

Brake discs are a crucial component in railway systems, ensuring safe and efficient braking operations. To ensure consistent quality and performance, standards such as EN 14535 – Part 2 have been established specifically for brake discs mounted onto the wheel. This standard outlines the dimensions and quality requirements that must be met for these critical parts.

1. Purpose and Scope

EN 14535 – Part 2 focuses on brake discs that are directly mounted onto the wheel. It specifies the dimensional and performance characteristics necessary for proper functioning within a railway system. This standard covers various aspects, including material composition, geometrical tolerances, hardness levels, and surface finish requirements.

2. Dimensional Requirements

The standard defines the dimensions of brake discs, including their diameter, thickness, and location of mounting holes or slots. These specifications ensure compatibility with the wheel’s design and ensure a proper fit.

3. Material Composition and Quality

EN 14535 – Part 2 emphasizes the importance of using high-quality materials for brake discs. The standard provides guidelines regarding the chemical composition, mechanical properties, and heat treatment processes required to meet specific performance criteria. These requirements help ensure durability and resistance to wear, corrosion, and thermal stress.

4. Geometrical Tolerances

To maintain optimal performance, the standard sets strict limits on the accepted variations in dimensions, such as flatness, parallelism, and runout. Adhering to these tolerances ensures smooth operation, minimizes vibrations, and prevents premature wear.

5. Hardness Levels

Brake discs must exhibit sufficient hardness to withstand the forces and temperatures experienced during braking. EN 14535 – Part 2 specifies the minimum hardness levels that must be achieved through appropriate heat treatment methods. This ensures the integrity and longevity of the brake disc under demanding operating conditions.

6. Surface Finish Requirements

The standard addresses the surface finish of brake discs, including roughness and cleanliness criteria. Smooth surfaces are essential to promote effective braking and prevent excessive wear on brake pads or shoes.

In summary, EN 14535 – Part 2 is a vital standard for the railway industry, specifically concerning brake discs mounted onto the wheel. It outlines the dimensional requirements, material composition, geometrical tolerances, hardness levels, and surface finish specifications necessary for reliable and efficient braking operations. By adhering to this standard, engineers and technical personnel can ensure the safe and optimal performance of railway systems.
