Purpose and objectives

The SN EN 15085-2+A2:2025 is a CEN standard that sets forth requirements for manufacturers involved in welding for railway applications. Its primary objective is to ensure the quality and safety of welded components in the railway industry by establishing classification levels and conformity assessment procedures. This standard aims to enhance the consistency of welding processes, promote effective welding coordination, and ensure that manufacturers meet the necessary quality assurance measures. By following this standard, manufacturers can demonstrate compliance and reliability in their welded products, thereby enhancing safety in railway operations.

Scope: who must comply

The SN EN 15085-2+A2:2025 standard applies to manufacturers engaged in the production of welded components for the railway sector. This includes a wide range of companies, from large-scale manufacturers to specialized welding shops. Typical industries affected by this standard encompass rail vehicle manufacturers, infrastructure providers, and service providers involved in railway applications. Compliance with the SN EN 15085-2+A2:2025 is crucial for these organizations to ensure that their welding processes meet the established quality and safety criteria, thereby safeguarding the integrity of railway operations.

How SN EN 15085-2+A2:2025 relates to other standards

The SN EN 15085-2+A2:2025 standard is part of a broader framework of welding standards. It is closely related to the following:

• ISO 3834: This is a standard that specifies quality requirements for fusion welding of metallic materials, complementing the requirements of SN EN 15085-2+A2:2025.
• EN 1090: This standard covers the execution of steel and aluminum structures, which includes welding requirements relevant to construction projects in the railway industry.
• ISO 14731: This standard outlines the responsibilities for welding coordination, providing guidelines that support the implementation of SN EN 15085-2+A2:2025.

Revision history and current status

The SN EN 15085-2+A2:2025 was published by the European Committee for Standardization (CEN) in 2025. This current revision reflects updates aimed at enhancing clarity and applicability of the welding requirements in the railway industry. The most recent changes include refined classification levels for welded components and more specific guidelines on the roles of welders and welding operators. These revisions ensure that the standard remains relevant and effective in promoting high-quality welding practices.
