This standard applies to the measurement of humidity of moist air from sea level to 3048 m (10,000 ft), within the drybulb temperature range of –50°C to 160°C (–58°F to 320°F),and within the dew-point temperature range of –50°C to 99°C (–58°F to 210°F). 2.2 This standard applies to methods for the direct measurement of wet-bulb temperature, dew-point temperature, relative humidity (RH), and humidity ratio. 2.3 This standard requires determining the uncertainty of direct humidity measurements due to various sources of errors
