IEC 61508 Industrial Functional Safety Professional (IFSP) Training

Our flagship program, delivered directly as an approved SGS-TÜV Saar partner. We systematically simplify the 10-part structure of the master standard so working engineers can apply it on real hardware — with practical guidance on risk assessment, Safety Integrity Level (SIL) determination, and software safety requirement validation.
