This standard specifies the calculation method of relative humidity when using a wet-bulb temperature meter to measure the dry wet-bulb temperature in environmental testing. Humidity data measured by a spherical or columnar mercury thermometer is suitable for calculating relative humidity in environmental testing. The standard provides an accurate relative humidity calculation method for experimenters, which helps to improve the accuracy and conformity of environmental test data.
