EN 15085 Certification for Railway Welding Quality | PRVÁ ZVÁRAČSKÁ, a. s.
Introduction
In the railway industry, welding plays a vital role in ensuring structural integrity and long-term operational safety. Components are exposed to constant vibration, dynamic loads, and environmental stress, making welding quality a critical factor.
The EN 15085 standard provides a comprehensive framework for welding railway vehicles and components, ensuring consistency, safety, and compliance across Europe.
With PRVÁ ZVÁRAČSKÁ, a. s., achieve certification and meet strict railway industry requirements.
What is EN 15085?
EN 15085 is a European standard that defines quality requirements for welding in railway applications. It applies to manufacturers, fabricators, and maintenance organizations involved in rail vehicles and components.
The standard ensures that:
- Welding processes are controlled and validated
- Personnel are properly qualified
- Materials are traceable
- Final products meet strict safety standards
Structure of EN 15085
The EN 15085 series consists of multiple parts, each addressing a specific area:
- EN 15085-1 – General requirements
- EN 15085-2 – Certification of welding manufacturers
- EN 15085-3 – Design requirements
- EN 15085-4 – Production requirements
- EN 15085-5 – Inspection, testing, and documentation
Together, these parts form a complete welding quality system for railway applications.
Certification Levels (CL Classes)
EN 15085 defines certification levels based on safety and application:
- CL1 – Critical safety components
- CL2 – Important structural parts
- CL3 – Standard components
- CL4 – Basic or non-critical components
Higher levels (CL1, CL2) require stricter controls and more advanced quality systems.
Typical Applications
EN 15085 is used in:
- Train and metro car body manufacturing
- Bogies and chassis fabrication
- Freight wagons
- Railway infrastructure components
- Maintenance and repair operations
It is essential for companies working in European railway supply chains.
