Railway Industry: IRIS (International Railway Industry Standard)


Since 2006, IRIS (International Railway Industry Standard) has been the most topical Business Management System related to railway industry, which is used and recognized world-wide. This system encompasses the whole line of the value added chain, e.g. design and development, production, sales, project management and purchasing, including subsuppliers.

The IRIS Standard was developed specially for railway industry by UNIFE (Association of European Railway Industries). Considering the railway specific requirements and features, it is based on a series of generic Standards. By now IRIS is a Standard for a Railway Business Management System, which is accepted world-wide and for which as many as 1200 Certificates have already been granted. Such a management system has been made necessary by the rapid technical changes of the vehicle fleet and the increased claims, even in the field of quality – the term of quality not only being restricted to product quality.

The differences to the Standards generally known and the ISO 9001 Standard, which is usable universally, are connected to two items:


  • the specific process approach to the important elements of engineering and production as well as maintenance and the electronic and mechanical contents ofvehicles;
  • considering the value creating processes throughout the supply chain – for a management system that only focuses on the end product definitely cannot assure the quality of an entire vehicle, which is made up of several thousands of single parts.

As the whole value added chain of all parts of vehicles is monitored and in connection with a structured, objective and traceable assessment system, this will, after each audit, provide the company with a clear picture of the quality situation. Consistent implementation of the IRIS requirements will demonstrably help to reduce failure costs at all levels of product realization. Hidden costs will be reduced by consistently keeping the processes. Thus the company’s revenue will be increased.

The audit result will be stated in per cent – the maximum value amounting to 100 %. The audit team can also make suggestions for improvement to the company. However, these suggestions are not aimed at being translated into action but at emphasizing their objectives and mode ofaction. Thanks to the assessment system within the audit procedure, the company will identify the effect of its endeavours relatively rapidly.

Manufacturers certified according to IRIS will be listed in the UNIFE Database. This database is an important information platform for buyers that are looking for potential suppliers.

At companies structured like this, the quality level of the products and of the complete vehicles can be demonstrated and compared to the requirements quite well. Evaluations of the “life cycle costs” and the non-scheduled failures/costs will furnish the relevant data. Some railway administrations have already signed a “Memorandum of Understanding on IRIS“.

All the registered IRIS Auditors are subject to a stringent selection procedure and are rail experts with experience in business systems as well as rail specific knowledge. Annual knowledge checks and further training of the auditors are compulsory.

After the accreditation process has been run through successfully, Quality Austria has been the only Austrian Certification Body to be accredited for IRIS (International Railway Industry Standard) by UNIFE (Association of European Railway Industries) since December 2014.
