Updated On: April 01, 2002
Editorial Change:
 
1.1.1 This test method covers the determination of the humidity of atmospheric air by means of wet- and dry-bulb temperature readings.

1.1.2 This test method is applicable for meteorological measurements at the earth's surface, for the purpose of the testing of materials, and for the determination of the relative humidity of most standard atmospheres and test atmospheres.

1.1.3 This test method is also applicable when the temperature of the wet bulb only is required. In this case, the instrument comprises a wet-bulb thermometer only.

1.1.4 Relative humidity (rh) does not denote a unit. Uncertainties in the relative humidity are expressed in the form U + u % rh, which means that the relative humidity is expected to lie in the range ( U - )% to ( U + )%, where U is the observed relative humidity. All uncertainties are at the 95% confidence level.
