C to 50 deg C and wet bulb depressions up to 15
degrees Celsius at 1013 hPa pressure
1b. Dew-point temperature from dry-bulb readings from
1 deg C to 50 deg C and wet-bulb depressions up to
15 degrees Celsius at 1013 hPa pressure
2a. Relative humidity from dry-bulb readings from 51 deg
C to 99 deg C and wet-bulb depressions up to 15
degrees Celsius at 1013 hPa pressure
2b. Dew-point temperature from dry-bulb readings from
51 deg C to 99 deg C and wet-bulb depressions up to
15 degrees Celsius at 1013 hPa pressure
3a. Relative humidity from dry-bulb readings from 2 deg
C to 98 deg C and wet-bulb depressions above 15
degrees Celsius at 1013 hPa pressure
3b. Dew-point temperature from dry-bulb readings from
2 deg C to 98 deg C and wet-bulb depressions above
15 degrees Celsius at 1013 hPa pressure
4. increase in relative humidity compared with 1972
edition, from dry-bulb readings from 2 deg C to
98 deg C and wet-bulb depressions up to 40 degrees
Celsius at 1013 hPa pressure
5. Correction for atmospheric pressure to relative
humidity values in tables 1a, 2a and 3a at a pressure
of 1013 hPa, from dry-bulb readings from 2 deg C to
98 deg C and pressures in hPa, for a wet-bulb
depression of 10 degrees Celsius
Contains tables and equations for the determination of relative humidity and dew point from the readings of a forced-ventilated wet- and dry-bulb hygrometer or aspirated psychrometer over the range of dry-bulb temperatures from 1°C to 99°C at 1013 hPa.
