EN 15085 Welding Certification: Elevating Railway Fabrication Quality, Safety & Global Compliance

In today’s rapidly evolving railway industry, safety, durability, and precision are non-negotiable. One of the most critical standards ensuring these requirements is EN 15085-2 Railway Certification, which governs the welding of railway vehicles and components.

For manufacturers aiming to enter or expand within the global railway supply chain, EN 15085-2 is more than just a certification—it is a mark of credibility, compliance, and technical excellence.

PRVÁ ZVÁRAČSKÁ, a. s., a recognized Manufacturer Certification Body (MCB) accredited by the European Committee for Welding of Railway Vehicles (ECWRV), plays a key role in certifying organizations to meet these stringent requirements.

Why EN 15085-2 Railway Certification Matters in Railway Manufacturing

Railway vehicles operate under extreme conditions—constant vibration, heavy loads, and long service life. Welding is at the core of these structures, making strict quality control essential.

EN 15085-2 Railway Certification ensures that:

• Welding processes are standardized and controlled
• Structures meet strict safety and regulatory requirements
• Manufacturers deliver consistent and reliable quality
• Risks of structural failure are significantly minimized

This makes the certification essential for companies involved in:

• Railway coach and locomotive manufacturing
• Wagon and metro production
• Fabrication of structural railway components

Scope of EN 15085-2 Railway Certification

EN 15085-2 Railway Certification applies to a wide range of railway applications, including:

• Design and manufacturing
• Repair and maintenance
• Assembly of welded components

Certified organizations typically produce:

• Bogies and chassis
• Underframes and car bodies
• Roofs, side walls, and end walls
• Couplers and braking systems
• Tanks, doors, and seating structures

EN 15085-2 Classification Levels Explained

The certification is divided into three Classification Levels (CL) based on safety relevance:

1. CL1 – Critical Safety Components

Applies to components where failure could directly impact railway safety.

Examples include:

• Bogies and wheelset structures
• Brake systems
• Load-bearing car bodies
• Fuel tanks and pressure containers

2. CL2 – Important Structural Components

Covers components with moderate safety importance.

Examples include:

• Interior structures
• Seating frames
• Air pipes and equipment supports
• Passenger-related components

3. CL3 – Non-Critical Components

Applies to simple parts with lower safety impact.

Examples include:

• Window frames
• Ventilation grilles
• Mounting brackets
• Interior fittings

Step-by-Step EN 15085-2 Railway Certification Process

Achieving EN 15085-2 Railway Certification involves a structured and detailed evaluation:

1. Documentation Review

Organizations must submit key documents such as WPS, WPQR, WPQ, welding manuals, weld maps, NDT procedures, and welding coordination qualifications (EN ISO 14731).

2. On-Site Audit

Expert auditors assess production facilities, welding equipment, personnel competence, and quality control systems to ensure compliance.

3. Testing & Verification

This includes non-destructive testing (VT, PT, UT, MT), visual inspections, and dimensional checks to verify weld integrity.

4. Quality System Validation

Verification of a robust welding quality management system ensures traceability, consistency, and compliance with EN 15085-2 requirements.
