ISO/TS 22163 Rail Quality Management Certification

Quality Management System (QMS) Certification for the Rail Industry

About the ISO/TS 22163 Standard

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.

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 audits in order to create a higher level of transparency throughout the railway supply chain.
