Preventing permanent damage to cable insulation during a fault.
The standard (now officially designated as IEC 60949 ) is the international benchmark for calculating the thermally permissible short-circuit currents for electrical cables.
Unlike the simpler adiabatic method, the full IEC 949 approach accounts for into surrounding materials like insulation or the cable sheath. IEC 60949:1988
