2.3 Atmosphere condition:
Relative humidity of the atmosphere couldn't exceed 50%
when the highest temperature is +40℃; much higher relative
humidity is allowable under the condition of lower
temperature, for example, when the temperature reaches
+20℃, the relative humidity is up to 90%. As for dews, which
contingently appear due to change of temperature, special
steps should be taken.
