BS EN 15085-1:2007+A1:2013

What is BS EN 15085-1 - Welding of railway vehicles and their components about?

BS EN 15085 is a European standard that discusses the welding of railway vehicles and components. BS EN 15085-1 is the first part of a multi-part series that applies to welding of metallic materials in the manufacture and maintenance of railway vehicles and their parts to ensure safety and stress factors relevant to railway operation.

For the railway environment, BS EN 15085-1 defines the certification and quality requirements for the welding manufacturer to undertake new building and repair work.

BS EN 15085-1 provides an essential link between performance requirements defined during design and achieving appropriate quality welds during production and the demonstration of the required quality by inspection.

This link is achieved by defining a weld performance class during design, which is based on safety and stress factors relevant to railway operation.

BS EN 15085-1 deal with welding steel and aluminium alloys including castings (e.g., Cu, Mg).

BS EN 15085-1 also provides general recommendations and definitions for welding railway vehicles and associated components. Except for specific provisions which are laid down contractually, BS EN 15085-1 applies to all assemblies, sub-assemblies or parts welded by any welding process, either manual, partly mechanized, fully mechanized or automatic welding as defined in EN ISO 4063.

Note 1: The principle of BS EN 15085-1 may also be applied for welding of other parent materials.

Note 2: BS EN 15085-1 does not deal with product qualification.

Note 3: Items of equipment subject to specific regulations are not relevant to the scope of BS EN 15085-1, e.g., air reservoirs according to EN 286-3 and EN 286-4.

Who is BS EN 15085-1 - Welding of railway vehicles and their components for?

BS EN 15085-1 on welding of railway vehicles and components is useful for:

• Manufacturers of railway vehicles
• Test centres
• Regulatory authorities

Why should you use BS EN 15085-1 - Welding of railway vehicles and their components?

Welding is a special process in the manufacture of railway vehicles and their parts. Weld performance class is for performance requirements of the welded joint as defined by the stress category and the safety category of the welded joint. Weld inspection class defines the inspections to be carried out for a given weld concerning the weld performance class.

BS EN 15085-1 guideline assists you with the general requirements on the welding process, consumables, and joint preparation for welding of railway vehicles and components.

With compliance and obedience to BS EN 15085-1, you can standardize the welding of railway vehicles and their components and ensure safety during railway operations.
