The current version is IEC 60949:2016 . If your "IEC 949" PDF does not include the 2016 modifications (especially correction factors for copper-clad aluminum), you are using outdated safety data.

Q: Why is IEC 949 compliance important? A: IEC 949 compliance is important for ensuring safety, increasing market access, reducing liability, and improving product quality. iec 949 pdf

The basic formula for permissible adiabatic short-circuit current ( IADcap I sub cap A cap D end-sub The current version is IEC 60949:2016

The standard formerly known as (now integrated into IEC 60949 ) provides the calculation methods for determining the thermally permissible short-circuit currents for electrical cables. It is primarily used to ensure that a cable’s conductor, screen, or sheath can withstand the rapid heat rise during a fault without exceeding its temperature limits. Core Content of IEC 60949 A: IEC 949 compliance is important for ensuring

: Reciprocal of the temperature coefficient of resistance (e.g., 234.5 for copper). Why Use Non-Adiabatic Calculations?
