Heat does not have time to escape. Useful for very short, intense faults where the insulating material acts as an insulator, trapping heat.

: It provides mathematical formulas to determine the short-circuit rating of cable conductors and metallic sheaths. Unlike simpler methods that assume no heat escapes the conductor (adiabatic), this standard accounts for heat loss into the surrounding insulation.

The most common use of the standard is to check if a conductor is large enough to survive a fault. The formula, derived from the principles of IEC 60949, is the Adiabatic Equation: [ S = \frac\sqrtI^2 \cdot tk ] Where: Heat does not have time to escape
