ANSI/ASHRAE 41.6-1994 (R2006) Standard Method for Measurement of Moist Air Properties

ANSI/ASHRAE 41.6-1994 (R2006) Standard Method for Measurement of Moist Air Properties is a reaffirmation of ASHRAE Standard 41.6-1994. This standard falls under the Standards Committee classification of Standard Method of Measurement. This standard was prepared under the auspices of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). It may be used, in whole or in part, by an association or government agency with due credit to ASHRAE. Adherence is strictly on a voluntary basis and is merely in the interest of obtaining uniform standards throughout the industry.

ANSI/ASHRAE 41.6-1994 (R2006) Standard Method for Measurement of Moist Air Properties sets forth recommended practices and procedures for the measurement and calculation of moist air properties in order to promote accurate measurement methods for specific use in the preparation of other ASHRAE standards.

ANSI/ASHRAE 41.6-1994 (R2006) Standard Method for Measurement of Moist Air Properties recommends procedures for measurement of moist air properties in connection with (a) the establishment of the desired moist air environment for tests of heating, refrigerating, humidifying, dehumidifying, and other air-conditioning equipment and (b) the determination of the quantity of moisture in airstreams moving through or within such equipment or spaces.

The scope of ANSI/ASHRAE 41.6-1994 (R2006) Standard Method for Measurement of Moist Air Properties is to describe various instruments and techniques for the measurement of moist air properties. Attention is given to methods appropriate for use in ASHRAE standard methods of test for rating or for determining compliance with ASHRAE environmental standards. These descriptions include the range of conditions over which their use is practicable, the associated attainable accuracy, and proper techniques of use to achieve desired accuracy. Specific attention is given to the wet-bulb and dry-bulb psychrometer and the dew-point hygrometer, while other methods are also discussed. A discussion also is presented concerning calibration, reference standards, and traceability to standards of the National Institute of Standards and Technology (NIST) to help ensure accurate measurements.

ANSI approved.
