Known U.S. / European Conflicts (10)

NIST SP 800-82 Rev 3↔IEC 62443-3-3· Control system cybersecuritySimilar
Map NIST controls to 62443 SRs; target SL2 minimum for SIS networks.
UFC 4-010-06↔IEC 62443-3-3· Facility control system securityPartial
UFC requires DoD RMF authorization; 62443 certification alone does not satisfy ATO.
IEC 61511↔DIN EN ISO 13849-1· Safety control systemsPartial
Partial alignment; supplemental U.S. testing or documentation required.
UFC 4-010-06↔IEC 62443· OT cybersecurityPartial
Partial alignment; supplemental U.S. testing or documentation required.
ASME PCC-2↔IEC 61511· Voltage levelsSimilar
Requirements broadly equivalent; document equivalency in design analysis.
UFGS 13 34 19↔IEC 61511· Fire doorsSimilar
Requirements broadly equivalent; document equivalency in design analysis.
UFGS 08 34 63↔IEC 61511· Crane designSimilar
Requirements broadly equivalent; document equivalency in design analysis.
UFGS 26 05 00↔EN 764-7· UPS systemsSignificant Difference
Fundamental differences; requires AHJ/NRTL review and likely redesign or re-certification.
NFPA 400↔IEC 61511· Generator testingSimilar
Requirements broadly equivalent; document equivalency in design analysis.
UFGS 44 11 00↔IEC 61511· NDT methodsSimilar
Requirements broadly equivalent; document equivalency in design analysis.
