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 documents 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 documents does not deal with product qualification.
NOTE This series of documents 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."

3.1
safety relevance
description of the consequences of a failure of a welded component with respect to the effects on persons,
facilities and the environment
Note 1 to entry: The safety relevance of a welded component is distinguished as follows:
Low: Failure of the welded component does not lead to any direct impairment of the overall function.
Consequential events with personal injuries are unlikely
Medium: Failure of the welded component leads to an impairment of the overall function and/or may lead to
consequential events with personal injuries
High: Failure of the welded component leads to consequential events with personal injuries and breakdown
of the overall function
Note 2 to entry: Safety relevance assessment should be done according to EN 50126 series.
4 Classification levels and activities of manufacturers
4.1 Classification level
Manufacturers and the components they weld are classified in three levels depending on the safety
relevance of the welded component (see 3.1).
The classification levels are defined as follows:
