Water vapor tolerance / water vapor capacity

The water vapor tolerance has the dimension of a pressure and is expressed in hPa. DIN 28426 describes the use of an indirect process to determine water vapor tolerance. The water vapor tolerance increases as the exhaust temperature of the pump rises and gas ballast flow q pV,Ballast increases. It decreases at higher ambient pressure.
