IRIS Certification Components®


The IRIS Certification® scheme comprises of:


ISO/TS 22163:2017

IRIS Certification Conformity assessment:2020

IRIS Certification Technology that includes the Audit-Tool, IRIS Portal and IRIS Certification database.



What is ISO/TS 22163:2017?


ISO/TS 22163:2017 is the standard specifying business management system requirements for rail organisations. ISO/TS 22163:2017 is largely based on ISO 9001:2015 that is a general quality management system standard used by millions of companies around the world. In addition, the ISO/TS 22163:2017 includes specific requirements tailor-made for the high quality business management in the railway sector. The standard functions as a formula describing the best practices for business management in the rail sector. This document is owned and managed by the International Organization for Standardization (ISO), available for purchase on their website as well as on the websites of national standardisation bodies.


How to become IRIS certified?


IRIS Certification Conformity assessment:2020


















Fulfilling the requirements brought out in the ISO/TS 22163:2017 does not automatically grant a company an IRIS Certificate. In addition to fulfilling the requirements specified in the ISO/TS 22163:2017 standard, the IRIS Conformity assessment:2020 defines rules and procedures that must be followed in order to be awarded with the certificate. Issued on 1 May 2020, the IRIS Certification Conformity assessment:2020 publication supersedes the existing “IRIS Certification rules rev. 03:2017” and the IRIS Addendum 2019. The new document is available for purchase via the IRIS Portal Shop here.


What is IRIS Technology?












IRIS Technology enables the functioning of the IRIS Certification scheme. Consisting of the IRIS portal, the Audit-Tool and the database, IRIS Technology offers the necessary tools for awarding and maintaing the IRIS Certification scheme as well as supporting companies in preparation of the audit.


IRIS portal refers to the domain. The portal has a section that is available for everybody without being registered to the system where visitors can find generic information about the IRIS Certification scheme, read news, see IRIS Certified companies and more. However, the majority of the IRIS portal is accessible only for registered companies and IRIS approved certification bodies offering an online platform for monitoring and storing data, exchanging audit information and more.


IRIS database is part of the IRIS portal providing all necessary information about the audits. Every passed audit report with an IRIS certificate will be included in the online database. The name and address of the audited company together with the scope and validity of the certificate are published. The audited company can choose to make more details of the audit available to their stakeholders by giving them specific access. Otherwise this information is strictly confidential.


IRIS Audit-Tool is an integral part of the IRIS Certification system used for recording and evaluating data as well as generating standardized reports of IRIS Certification audits. IRIS Audit-Tool is essential for certification bodies during an IRIS Certification audit but also allows all rail companies to use the tool to increase their quality performance internally. The Tool can be purchased here by all rail companies seeking IRIS Certification during an internal audit allowing to increase the quality performance and prepare its business management systems for IRIS Certification audit.


Quality Performance Levels


Quality performance levels are rewarded to all IRIS Certified companies in order to enhance the overall quality of the rail sector by focusing on the quality performance of rail businesses. There are three quality performance levels – Bronze, Silver and Gold – out of which Bronze and Silver are currently available for audited companies. In order to achieve a higher quality performance level, companies have to fulfil additional criteria improving the performance of their businesses. Quality performance level is displayed in the IRIS portal together with other information related to all IRIS Certified companies. Quality performance levels confirm not only the implementation of a quality management system but also the application and the measured results for the stakeholders.



Objectivity and Transparency












Objectivity and transparency are guaranteed by only using approved and independent certification bodies, known and recognized in the industry. The requirements for certification bodies and auditors are regulated. All certification bodies shall have an accreditation in accordance with ISO/IEC 17021:2015 and an approval from the IRIS Unit. Only IRIS approved auditors who have participated in the IRIS training and who have passed a written and oral examination can perform IRIS Certification audits. The auditors can only audit against their competence in a certain product category. Finally, auditors who comply with these requirements can work for their IRIS approved sponsor certification body. Auditors are allowed to work for multiple certification bodies.



How does my Company Benefit from IRIS Certification®?


The successful implementation of the IRIS Certification creates a win-win situation for all stakeholders - equipment manufacturers, system integrators, operators and business partners.


Equipment Manufacturers











Equipment manufacturers are able to improve their quality level and therefore promote a greater quality image. This enhances equipment manufacturers’ competitiveness, increases their value and visibility in the market. IRIS Portal offers IRIS Certified companies a platform to share their information to system integrators and prospective clients, on approval of the audited company.


In addition, following the best practices required for obtaining the IRIS Certification, allows equipment manufacturers to enhance business management systems and increase efficiency. This in turn results in lowered costs, higher product quality and customer satisfaction.


Finally, equipment manufacturers are able to save time by only having to apply once for the certification, for both ISO 9001 and IRIS Certification at the same time.


System Integrators











Transparent requirements are acceptable and applicable to all parties and become an integral part of the management systems in the participating companies.This results in improved quality among the various production sites of system integrators. A uniform quality standard considerably simplifies the process of evaluating and approving suppliers, removing the need for system integrators‘ own approval audits. Additionally, system integrators are able to access accurate and reliable data from the common IRIS web database.













Operators benefit from the improvements across the entire supply chain, with enhanced equipment, rolling stock and signaling. They are able to rely on a demanding, internationally recognized standard for the whole industry. As a result, quality, safety and reliability increase as well as business management processes of the industry. Operators have also actively contributed to the IRIS Certification rules and IRQB Guidelines by highlighting necessary implementations.
