EN 15085 Railway applications – Welding of railway vehicles and components

The EN 15085 standard series applies to the design, manufacturing, testing and conformity assessment of welded railway vehicles, components and assemblies. It sets requirements for the quality system, welding process approvals, as well as performance qualifications for welder and welding operator.

The maintenance and hence repair of in-service railway vehicles is covered in DIN 27201-6.  A manufacturer who performs maintenance and repair work is required to receive certification according to DIN 26701, as this series of standards establishes the certification and the quality requirements for welding operations in production and maintenance work.

ECE Global has worked with over 400 companies related with EN 15085, AWS D15.1, AWS D1.1, AWS D1.2 and other specification.

We are familiar with many local or additional regulations and requirements, such as AWS D15.1, AWS D1.1, ASME, DIN 6700, DIN 27201, ISO 15614, ISO 15613, ISO 9606, and more.

ECE Gobal’s vast experience prevents “reinventing the wheel” and provides improvement or optimization opportunities in an effort to compliance.

Our experts performed either the accredited certification or provided services related to the implementation of systems, process and qualifications, but not both and one manufacturer.

Background Information

EN 15085 Scope

The series of European Standards EN 15085 “Railway applications – Welding of railway vehicles and components” consists of the following parts:

EN 15085 Part 1: General

  • EN 15085 Part 1 provides an overview and scope of the 15085 series of standards and how it applies to the welding of metallic materials in the manufacture and maintenance of railway vehicles and their parts.

EN 15085 Part 2: Quality requirements and certification of welding manufacturer

  • EN 15085 Part 2 of the standard defines the certification and quality requirements for the welding manufacturer to undertake for new fabrication and repair work.
  • It then provides an essential link between performance requirements defined during design to achieve the appropriate quality welds during production and the demonstration of the required quality by inspection.

EN 15085 Part 3: Design requirements

  • EN 15085 Part 3 defines weld performance class during design, which is based on safety and stress factors relevant to railway operation.
  • Quality levels of imperfections are assigned to weld performance classes to ensure a certain level of performance intended during design.

EN 15085 Part 4: Production requirements

  • Based on the weld performance classes, certification levels for production, as well as inspection and testing and qualifications for welding personnel of the manufacturer are specified.

EN 15085 Part 5: Inspection, testing and documentation

  • This standard deals with inspections and testing to be executed on the welds, destructive as well as non-destructive tests to be performed and necessary documentation to issue to declare the conformity of the products.
  • The EN 15085 series of standards does not deal with product qualification.


EN 15085 Governing Standards

For US manufacturers, implemented welding procedures that meet the AWS (American Welding Society) requirements will be approved according to the applicable European Norms and Requirements. A list of Norms (see below) includes the applicable welding standards.

Some of the governing standards for a Manufacturers Approval according to EN 15085 Parts 1-5 – Welding of Rail Road Vehicles and Vehicle Parts are:

EN ISO 14731:2006, Welding coordination – Tasks and responsibilities (ISO 14731:2006)

EN ISO 3834 (all parts), Quality requirements for fusion welding of metallic materials

DIN EN 12663 Railway applications – Structural requirements of railway vehicles bodies

EN ISO 15609 (all parts), Specification and qualification of welding procedures for metallic materials – Welding procedure specification

EN ISO 15614 (part 1) Specification and qualification of welding procedures for metallic materials – Welding procedure test

  • Describes general rules for the specification and approval of welding for metallic materials.
  • Refers to several other standards.
  • Assumes the welding procedure specifications are used in production by competent welders.
  • Applies when approval of the welding procedure is required.
  • Covers normative references, definitions, specification of welding procedures and approval of welding procedure.

EN ISO 9606-1 (replaced EN 287-1), Qualification test of welders – Fusion welding – Part 1: Steels

  • Describes essential requirements, ranges of approval, test conditions, acceptance requirements and certification for the approval testing welder performance for the welding of steels.
  • During the approval test the welder should be required to show adequate practical experience and job knowledge.
  • Applicable when the welder’s approval testing is required by the purchaser, inspection authorities or other organizations.
  • Applies to the approval testing welders for the fusion welding of steels.
  • Includes those fusion welding processes which are designated as manual or partly mechanized welding.
  • It does not cover fully mechanized for fully automatic processes (EN ISO 14732 (replaced EN 1418))

EN ISO 9606-2, Qualification test of welders – Fusion welding – Part 2: Aluminum and aluminum alloys (ISO 9606-2:2004) – Description equivalent to above EN 287-1

EN ISO/IEC 17025, General requirements for the competence of testing and calibration laboratories (ISO/IEC 17025:2005)

The European community has defined rules and regulations for railway applications to ensure the safety of people, the environment and equipment operation. The process of harmonizing the various standards for railway applications across the EU members has been a gradual process that has culminated in the publication and implementation of the EN 15085 series of standards in 2007. The diagram below illustrates how the new standards are implemented based on the European Directives issued by the EU Parliament and supported by local rules and sound engineering practices to achieve a standard that is mandatory across all of the EU countries.
