The recommendations from this study for HS test conditions in IEC TS 63126:2020.

Hot-spot endurance test	Standard (IEC 61215:2021)	Level 1 (70 °C < T₉₈ ≤ 80 °C)	Level 2 (80 °C < T₉₈ ≤ 90 °C)
IEC TS 63126:2020*	55±15 °C	60±10 °C	70±10 °C
Proposal of this study	55±15 °C	75±10 °C	85±10 °C

*When IEC TS 63126:2020 was published, still IEC 61215-2:2016 was in action and module temperature of the HS test was 50±10 °C.
