This draft amendment is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 256.

This draft amendment A1, if approved, will modify the European Standard EN 15085-2:2020. If this draft becomes an
amendment, CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for
inclusion of this amendment into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

European foreword
This document (EN 15085-2:2020/prA1:2021) has been prepared by Technical Committee CEN/TC 256
“Railway applications” the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of EU
Directive(s) / Regulation(s).

1 Modification to Introduction
Replace the current introduction by the following:
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.
