ISO 8502-4 describes whether conditions at the job are suitable for painting or not.

DewCheck4: Complex Coating Climate

As ISO 8502-4 indicates the ideal coating climate depends on many, often instable, parameters:
Parameter
Air temperature:
Relative humidity:
Dewpoint temperature:
Surface temperature:
Influenced by
wind, sun, shadow, ventilation, heating, ...
air temperature, wind, ventilation, rain, location, type of coating (water based)
calculated using the two above mentioned instable parameters.
type of surface material (steel, aluminium, concrete etc.), air temperature, wind,
sun, shadow, mass of surface, shape and type of structure....
