IEEE 1584.2-2025
New data collection standard for arc flash studies
The IEEE 1584 family welcomes a third document: IEEE Guide and Checklists for Data Collection for Performing an Arc-Flash Hazard Calculation Study in Accordance with IEEE Std 1584™ and IEEE Std 1584.1™ for Systems Operating at Three-Phase 50/60 Hz AC 1000 V and Below. Published September 19, 2025 and ANSI approved February 11, 2026.
The other two, for reference
- IEEE 1584-2018 - IEEE Guide for Performing Arc-Flash Hazard Calculations
- IEEE 1584.1-2022 - IEEE Guide for the Specification of Scope and Deliverable Requirements for an Arc-Flash Hazard Calculation Study in Accordance with IEEE Std 1584
How this may affect your facility
- Field data for an arc flash study now has an official IEEE checklist, with equipment-specific lists for switchgear, switchboards, panelboards, and motor control centers.
- Scope is arc flash studies at 1000 V and below. Data collection for short circuit and coordination studies is outside it.
Next up
A revision to the incident energy models (IEEE 1584) is on the IEEE schedule as active project P1584, to supersede 1584-2018. Scope stays 208 V to 15 kV three-phase AC. No draft or ballot date has been published yet.
