(PDF) Humidity and Dew Point: Their Effect on Corrosion

However, unlike relative humidity, if dew point increases, it is only because the amount of moisture increases. So dew point is strictly a measure of absolute humidity or the amount of moisture in the air. This understanding of dew point and condensation can help explain corrosion mechanisms and problems with paint application.
