Certification according to EN 15085-2 is an established element of quality assurance and is always more required in Europe as well as outside of Europe for the acceptance of welded works in railway market and industry.
Welding and joining processes, in particular on load-bearing structures, require special attention and implementation of quality criteria of EN15085 ensure that the fundamental technical welding requirements are met by manufacturing companies.


RINA SERVICES is a certification body with deep experience on welding processes in many industrial sectors including railway sector.
RINA SERVICES operates as manufacturer certification body recognized by National safety authority for railway traffic (ANSF) and National accreditation body (Accredia).


The audit’s duration depends on certification level (CL) required by manufacturer and size of company in terms of number of workers involved in manufacturing activities by welding.
The validity of the certificate is limited to a maximum of 3 years. During the period of validity RINA verifies at least annually compliance with the requirements of the standard. Before the certificate expires the welding manufacturer may request RINA to renew it.
