EN 286- Part 4: Aluminium Alloy Pressure Vessels for Railway Rolling Stock

EN 286- Part 4 is a prominent industry standard that focuses on aluminium alloy pressure vessels designed specifically for air braking equipment and auxiliary pneumatic equipment used in railway rolling stock. This standard sets forth essential requirements and guidelines to ensure the safe and efficient operation of these pressure vessels within the railway industry.

1. Purpose and Scope:

EN 286- Part 4 establishes the necessary specifications for the design, construction, and testing of aluminium alloy pressure vessels used in the context of air braking systems and auxiliary pneumatic equipment in railway rolling stock. The standard aims to guarantee the integrity and reliability of these pressure vessels, ensuring they withstand the demanding operating conditions encountered in railway applications.

2. Design Considerations:

The standard specifies various aspects that need to be taken into account during the design phase. These include the vessel’s dimensions, materials, wall thickness, reinforcement, fittings, connections, safety devices, and pressure ratings. Compliance with EN 286- Part 4 ensures that the pressure vessels are robust, corrosion-resistant, and capable of withstanding the mechanical stresses and temperature variations experienced in railway environments.

3. Testing and Certification:

EN 286- Part 4 outlines rigorous testing procedures and criteria that pressure vessels must undergo to verify their compliance with the standard. These tests include hydrostatic pressure testing, fatigue testing, and burst pressure testing, among others. Additionally, certification bodies assess the manufacturing processes and quality control systems to grant the necessary certifications, confirming that the pressure vessels meet the required safety and performance standards.
