3 ]% e  L  g; ~Can these two be harmonized?
Decision:
When conducting clause 10.12 Humidity-freeze test per IEC 61215-2005 Ed.2,
Figure 12, use clause 10.12 Humidity-freeze test of IEC61646-2008 Ed.2, Figure
5. There will be no RH control requirement during temperature transitions
between room temperature and 85°C.
