IEC 61641, titled "Application of metal-enclosed switchgear and controlgear for rated voltages above 1 kV and up to and including 52 kV — Guidelines for testing of switchgear for internal arc classification (IAC) — Verification by application of the power-frequency voltage withstand test," (note: exact title may vary by edition) is a technical standard providing guidelines and test procedures related to internal arcing faults in high-voltage metal-enclosed switchgear. Its core purpose is to help manufacturers, test houses, and end-users evaluate and verify the internal arc performance and classification (IAC) of switchgear assemblies to improve safety and limit damage and personnel hazard in the event of internal arcs.

Here are the specific helpful features defined in the standard that you will find detailed in the PDF: iec 61641 pdf

The testing procedure simulates a worst-case scenario where a fault (such as a forgotten tool or vermin) creates a plasma arc between live parts. IEC TR 61641:2014 IEC TR 61641:2014 While both address arc hazards,

While both address arc hazards, they serve different safety functions: IEC TR 61641 Equipment containment and pressure relief. Calculating incident energy for PPE selection. Goal Verify the assembly can withstand an internal arc. Protect workers during live maintenance/operation. Standard Type Technical Report (Guidance). Calculation Guide. 5. Critical Technical Considerations How to Increase Safety of LV Switchgear using IEC TR 61641 Protect workers during live maintenance/operation
