Updated standard and guide
Institute of Electrical and Electronics Engineers (IEEE) standard titled IEEE 1584
IEEE Guide for Performing Arc-Flash Hazard Calculations.
The updated standard and guide, IEEE 1584-2018 - Guide for Performing Arc-Flash Hazard Calculations, was published on November 30, 2018. This guide provides mathematical models for designers and facility operators to apply in determining the arc-flash hazard distance and the incident energy to which workers could be exposed during their work on or near electrical equipment.
The updates to IEEE 1584-2018 are based on extensive collaborative research undertaken by IEEE and NFPA. The original IEEE 1584-2002 model was re-evaluated to consider new technical information related to arcing fault physics. This resulted in a specific review of the test box sizes and electrode configurations. The range of the IEEE 1584 model has been changed and is now segregated into two sets—208 V to 600 V and 601 V to 15 kV—with each set having several parameters, such as bolted fault current and conductor spacing. Engineering Professionals should consult the IEEE 1584-2018 standard for a more detailed review and additional information.
Note that for systems outside the range of the IEEE 1584 model, including DC systems, other methods are available for calculating arc flash hazard incident energy. Several of these methods are summarized in CSA Z462-18 Workplace Electrical Safety, Appendix D, which specifically references the IEEE 1584-2002 standard; therefore, Engineering Professionals are advised to ensure they review the specific technical requirements of the IEEE 1584-2018 standard.
