Quality Management System Certification for the Rail Industry

What is ISO/TS 22163?

ISO/TS 22163 is the global standard for quality management systems in the rail industry. It is based on the ISO 9001 quality management standard, with the addition of rail-specific requirements. Released in May 2017, it replaced the previous quality standard IRIS Rev. 02.

Why is IRIS ISO/TS 22163 certification important?

The ISO/TS 22163 was created to ensure higher quality standards in terms of facilities, operating equipment, and services. It aims to achieve global uniformity in language, assessment guidelines, and IRIS audits to create a higher level of transparency throughout the railway supply chain.

Rail industry organisations that achieve IRIS ISO/TS 22163 certification and set up IRIS management systems enjoy multiple benefits:

  • Deliver consistently high standards of quality
  • Comply with railway quality management standards
  • Discover quality management problems and resolve them fast
  • Gain a competitive edge by demonstrating your dedication to quality

The IRIS railway certification enables clients to verify the quality and safety aspects of the rail industry and the methods used to produce and apply them. This transparency helps build confidence. In addition, the IRIS audit is valuable to the industry to innovate and develop their business and services.


Some benefits of IRIS compliance include:

  • Implementation of a QM system, particularly for railways
  • Enhanced quality standards
  • Increased customer satisfaction
  • Increased chances of winning tenders
  • Reduced risk of liability
