EN 15085 certification for the railway sector

EN 15085 certification is now an essential requirement for operating in the railway sector, ensuring the quality of welding processes and accessing European markets without obstacles. For many companies, this means being able to demonstrate compliance, business continuity and the ability to respond to the demands of railway manufacturers and safety authorities. 

DNV supports organizations on this path by offering accredited certification according to the EN 15085 standard, which is recognized both nationally and internationally. Accredia's accreditation according to ISO/IEC 17065, which has just been extended to DNV, ensures customers independent, impartial assessments that are fully aligned with Italian and European regulatory requirements. 

For Italian companies in the railway sector, operating in compliance with regulations is essential. DNV provides: 

  • ANSFISA recognition, which allows you to meet the additional requirements required in Italy for the certification of railway welding. 
  • Participation in the ECWRV system, which allows companies to obtain valid and accepted recognition in the European market, simplifying entry into new countries and collaboration with foreign partners. 

The EN 15085 process is managed in a transparent and guided way, so as to give companies certainty about the steps to be taken: 

  1. Initial pre-assessment to identify specific needs, gaps and priorities. 
  2. Formal request and planning of audits according to the customer's timing and availability. 
  3. Document and onsite audits on processes, traceability, controls and quality requirements. 
  4. Final evaluation and issuance of the certificate, recognized at national and European level. 
  5. Periodic surveillance to maintain compliance over time and manage any regulatory updates. 

Companies in the railway sector operate in a complex technical environment. For this reason, DNV provides auditors with specialized skills in the certification of welding processes and management systems, constantly updated on EN, IEC standards and the guidelines of Italian and European authorities. Customer value is a reliable, accurate evaluation process that is aligned with the operational needs of workshops and quality managers.
