The humidity limits are derived from a psychrometric chart using a maximum wet bulb temperature of 29
_
C. The highest
RH (20%) at the maximum temperature (+60
_
C) diverges from the psychrometric chart (which would indicate 6%). The
20% number is a practical limit. Test chambers cannot be set below this number.
