SN EN 15085-1:2023 is a standard published by the Swiss Association for Standardization (SNV) that outlines the requirements for welding railway vehicles and their components. This standard is essential for ensuring safety, quality, and reliability in the manufacturing processes used within the railway industry.

Purpose and objectives

The primary objective of SN EN 15085-1:2023 is to provide guidelines for the welding of railway vehicles and components to ensure that the resulting assemblies meet safety and quality standards. The standard aims to harmonize practices across the railway sector, promoting international compliance and reliability in manufacturing. By establishing clear requirements for welding processes, the standard helps manufacturers minimize risks associated with welding defects and enhances the overall durability and safety of railway vehicles.

Scope: who must comply

SN EN 15085-1:2023 applies to organizations involved in the design, construction, and maintenance of railway vehicles and components. This includes:

• Manufacturers of railway vehicles and subassemblies.
• Organizations providing welding services within the railway sector.
• Maintenance companies responsible for the upkeep of railway equipment.

Typical profiles include large-scale manufacturers, specialized welding companies, and maintenance facilities that adhere to the regulatory requirements of the railway industry. Compliance with this standard is crucial for ensuring that all welded components meet the necessary safety and operational standards.

How SN EN 15085-1:2023 relates to other standards

SN EN 15085-1:2023 is part of a broader framework of standards governing welding and manufacturing practices. Related standards include:

• EN ISO 4063: This standard provides a classification system for welding processes, which is relevant for ensuring the correct methods are employed in compliance with SN EN 15085-1:2023.
