ASTM D4230-02e1<\/h3>\n

Historical Standard: Standard Test Method of Measuring Humidity with Cooled-Surface Condensation (Dew-Point) Hygrometer<\/h4>\n
\n

ASTM D4230<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers the determination of the thermodynamic dew- or frost-point temperature of ambient air by the condensation of water vapor on a cooled surface. For brevity this is referred to in this method as the condensation temperature.<\/p>\n

1.2 This test method is applicable for the range of condensation temperatures from 60\u00b0C to -70\u00b0C.<\/p>\n

1.3 This test method includes a general description of the instrumentation and operational procedures, including site selection, to be used for obtaining the measurements and a description of the procedures to be used for calculating the results.<\/p>\n

1.4 This test method is applicable for the continuous measurement of ambient humidity in the natural atmosphere on a stationary platform.<\/p>\n

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/i> For specific precautionary statements, see Section 8.<\/p>\n
