Partial alignment; supplemental U.S. testing or documentation required.
UL 508A↔IEC 60204-1· Industrial machinery electricalPartial
Partial alignment; supplemental U.S. testing or documentation required.
IEEE 1584↔IEC 61482· Arc flashSignificant Difference
Fundamental differences; requires AHJ/NRTL review and likely redesign or re-certification.
UFC 4-010-06↔IEC 62443· OT cybersecurityPartial
