Highest quality and process reliability
With an IRIS certification, companies ensure that their products and processes meet the strict requirements of the railway industry. Consistent error prevention and continuous process optimisation increase reliability and help to reduce supply chain failures.
Recognition and market access
IRIS Certification® is a globally recognised system within the rail vehicle industry. A certified quality management system makes it easier for companies to access important markets and strengthens their position in the supply chain of well-known vehicle manufacturers and railway operators.
Clear and optimised processes
IRIS Certification® promotes a structured approach in all areas of the company. Thus, sources of error are minimised, workflows are made more efficient and processes are clearly defined. This leads to higher quality, improved safety and increased customer satisfaction.
If you feel fit for the standard, you are welcome to use the form above to register for certification. Otherwise, your path to an IRIS certification could look like this:

#1 – Building up the system
Implement your management system in accordance with the requirements of the standard so that you are ready for your first external certification audit by SQS.
#2 – Registration for the certification
After registering for certification, you can benefit from a preliminary talk or pre-audit. The pre-audit identifies system-relevant gaps and enables efficient certification.
#3 – Auditing
We first review your system documentation, assess your readiness for certification and draw up a detailed audit plan together with you. Our auditors then visit your company to assess the relevant test objects and the maturity degree of the management system and compile a report.
#4 – Certificate with a three-year validity
If the report is positive, you receive the certificate in digital and printed form. You can communicate it internally and externally for three years. Annual audits ensure compliance with the standard and enable continuous improvements. A comprehensive recertification takes place after three years.
The duration depends on the size of the company, the complexity of the processes and the degree of preparation. Both well-organised documentation and preparation speed up the procedure.
The certificate is valid for three years. During this time, a surveillance audit is carried out every year and recertification audit takes place after three years.
The costs vary depending on the size and complexity of the organisation. We would be happy to provide you with a customised offer.
No, our core competence is certification. However, if required, we will be happy to connect you with external experts or organise training courses so that you can optimally prepare for certification.
The certification body checks neutrally and independently whether your quality management system fulfils the requirements of IRIS Certification® and issues the certificate if the audit report is positive.
There is a central online database for IRIS certificates at www.iris-rail.org. To check the validity of a certificate, you can search there either by the name of the company, the registration number or other search criteria (such as location or scope).
If non-conformities are identified during an audit, the company is given a deadline to implement corrective measures. The certification cannot be issued or maintained without successful implementation.
IRIS is based on the principles of a quality management system (ISO 9001), but includes additional requirements that are specifically tailored to the railway industry, particularly with regard to safety, risk management and supplier control.
IRIS Certification® considers customer-specific and railway-specific requirements. Therefore, these must be integrated into the management system to fully meet the requirements of the railway industry.
A successful IRIS certification shows that a company fulfils the highest quality and safety standards and is continuously developing. This strengthens the trust of customers, investors and business partners and can secure the company's competitive position in the long term.
