Why IRIS Certification Is More Demanding Than ISO 9001
IRIS — the Business Management System Standard for the Railway Sector (ISO/TS 22163) — extends ISO 9001 with rail-specific requirements covering project management, RAMS (Reliability, Availability, Maintainability, Safety), maintenance management and supply chain control. Organisations from non-rail sectors entering the rail supply chain consistently underestimate the depth of these additional requirements.
