Seefeld, September 28, 2026 - TQ-Group, one of Germany's leading technology service providers, has successfully achieved IRIS Certification® (International Railway Industry Standard) and has been awarded Performance Level Bronze.
For companies undergoing the certification process for the first time, Bronze represents the highest possible performance level. The certification confirms that TQ meets the specific quality requirements of the international railway industry and is now listed in the official UNIFE IRIS Certification® database. The certificate was officially presented during InnoTrans 2026 at the UNIFE exhibition stand.
IRIS Certification® is one of the railway industry's most important quality standards. Developed by the European Rail Supply Industry Association (UNIFE), it sets demanding requirements for quality management, process reliability and continuous improvement throughout the entire supply chain. For TQ, the certification marks another important milestone in expanding its expertise and activities within the international railway and mobility sector.
As part of the certification process, TQ's integrated management system underwent a comprehensive audit conducted by DEKRA Certification. The company demonstrated a high level of compliance with the applicable requirements, achieved an outstanding overall assessment and received explicit recognition from the audit team.
A Strong Quality Credential for the International Railway Market
With the successful certification, TQ further strengthens its position as a development and manufacturing partner for railway industry customers. For many manufacturers and operators, IRIS Certification® serves as an important proof of compliance with industry-specific quality requirements and is often a prerequisite for new projects and tenders. In addition, the standard promotes robust processes, greater transparency throughout the supply chain and the continuous improvement of quality and safety.

Sybille Stieglbauer, Deputy Head of Quality Management at TQ and Project Manager for the certification project, adds: "In many areas, the IRIS standard goes well beyond the requirements of conventional quality management systems. We are therefore particularly pleased to have achieved Performance Level Bronze immediately with our initial certification. This result confirms the high maturity of our processes and the outstanding cross-functional collaboration throughout the entire TQ Group."
Sascha Langermann, Co-Auditor at DEKRA Certification, comments: "TQ achieved an exceptionally strong result during the IRIS certification process. Reaching Performance Level Bronze at the first attempt is by no means a given and reflects the thorough preparation and strong commitment of everyone involved. The quality management system demonstrates a high level of maturity, with processes that are not only well documented but also consistently implemented in practice. TQ has established an excellent foundation for its continued growth in the railway market."
