The official repository of all IEC standards.

To put it simply, imagine a power cable is hit by a massive short-circuit. The cable heats up instantly. The standard provides a mathematical framework to calculate the exact current the cable can handle for a split second before the insulation melts, without failing.

For the full text—including the complex empirical coefficients for non-adiabatic calculation of screens and small conductors—purchasing the standard from an accredited retailer is the only way to ensure you are working with the authentic, legally-binding document. Use this guide as your roadmap; let the official purchase be your final destination.

IEC 60949 introduces a correction factor (ε) to account for heat dissipation into the insulation: The official repository of all IEC standards

In the field of electrical engineering, particularly within power systems and cable installation design, safety and precision are paramount. One of the critical standards governing this safety is , titled "Calculation of thermally permissible short-circuit currents, taking into account non-adiabatic heating effects." The standard provides a mathematical framework to calculate

: Calculate a factor that accounts for the heat absorbed by adjacent materials.

It calculates the maximum allowable short-circuit current ( ) a cable conductor can handle within a specific time ( ) before the insulation suffers thermal damage.
