Establishes the physiological effects of electric current and calculates tolerable body current limits based on body weight (50 kg or 70 kg models).
The , titled the "IEEE Guide for Safety in AC Substation Grounding," provides the definitive methodology for designing and evaluating grounding systems to ensure personnel safety during electrical faults. It primarily addresses the mitigation of hazardous touch and step voltages that can occur when a fault current is discharged into the earth.

The standard updated the decrement factor ($D_f$) calculations. This factor accounts for the asymmetry of the fault current wave (the DC offset). The 2013 revision provided more detailed methods for calculating the RMS magnitude of the fault current, ensuring the grid is sized for the worst-case thermal scenario.
