The minimum humidity level for class A3 is the higher (more moisture) of the -12°C dew point and
the 8% relative humidity. These intersect at approximately 25°C. Below this intersection (~25°C),
the dew point (-12°C) represents the minimum moisture level; above the intersection, relative
humidity (8%) is the minimum.
