Overview

EN 15085-1:2023 - "Railway applications - Welding of railway vehicles and components - Part 1: General" is the CEN standard that defines the terms and general requirements for welding in the railway sector. Applicable to all assemblies, sub‑assemblies and parts welded by any process (manual, partly mechanized, fully mechanized or automatic) as defined in EN ISO 4063, this Part 1 provides the foundational vocabulary and framework used across the EN 15085 series for quality control and safety in railway welding.

Key Topics

• Scope and terminology: Establishes key definitions such as classification level (CL), safety relevance, weld performance class (CP), and weld inspection class (CT) using CEN/TR 14599, EN ISO 17659 and EN 45020 as references.
• General requirements: Sets expectations that manufacturers demonstrate control over welding quality primarily through manufacturer classification, welder and welding operator qualification, and welding procedure and production weld-test qualification.
• Interface with welding quality standards: Connects welding requirements with EN ISO 3834 (quality requirements for fusion welding) and links weld performance classes to stress and safety categories (see EN 15085-3:2022).
• Other applicable regulations: Clarifies items excluded or governed by specific legislation (e.g., pressure vessels) and introduces rules for trade-supplied components, where compatibility with railway conditions must be proven via technical specifications, type/endurance tests, calculation reports or return of experience.
• Annex A - Welding on tank wagons: Normative guidance distinguishing underframe welding (EN 15085 scope) from tank welding (subject to RID and competent authority approval).

Applications

EN 15085-1:2023 is used to:

• Establish a common vocabulary and baseline requirements for railway welding activities.
• Guide manufacturers in selecting and documenting welding processes, qualification evidence and inspection regimes.
• Support design teams in defining weld performance class and weld inspection class requirements.
• Assist certification bodies, procurement teams and maintenance organizations in assessing supplier capability and compliance. Typical users: rolling stock manufacturers, subcontractors, maintenance workshops, welding engineers, NDT personnel and regulatory/certification bodies.

Related Standards

• EN 15085-2:2020 - Requirements for welding manufacturer
• EN 15085-3:2022 - Design requirements (stress and safety categories)
• EN 15085-4:2023 - Production requirements
• EN 15085-5:2023 - Inspection, testing and documentation
• EN 15085-6:2022 - Maintenance welding requirements
• EN ISO 4063, EN ISO 3834, EN ISO 9606, EN ISO 9712

EN 15085-1:2023 is essential for consistent, safe and auditable welding practice across the railway sector and serves as the terminology and general-requirements backbone for the EN 15085 series.

Introduction
Welding is a special process in the manufacture of railway vehicles and their parts. The required
provisions for this process are laid down in the standards series EN ISO 3834. The basis of these
provisions is the basic technical welding standards with respect to the special requirements for the
construction of railway vehicles.
This series of standards applies to welding of metallic materials in the manufacture and maintenance of
railway vehicles and their parts.
It describes the control for the welding process for railway vehicles and their components for new
manufacture and maintenance.
With respect to the railway environment, this series of standards defines the quality requirements for
the welding manufacturer to undertake new building and repair work.
Components, parts and subassemblies are assigned a classification level, based on their safety relevance.
According to these levels, qualifications for welding personnel of the manufacturer are specified.
This series provides an essential link between the weld performance class defined during design, the
quality of the weld, and the demonstration of the required quality by inspection.
This series of standards does not deal with product qualification.
NOTE This series of standards can also be used by internal and external parties, including certification bodies,
to assess the organization's ability to meet customer, regulatory and the organization's own requirements.
