This is a reaffirmation of ASHRAE Standard 94.1-2002. 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 merely in the interests of obtaining uniform standards throughout the industry.

This latent Standard Method of Measurement or Test has been many years under development by a group of volunteers representing users, design engineers, manufacturers, scientists, and the federal government. Work sponsored by the U.S. Department of Energy through government laboratories has been especially helpful in accomplishing this step, particularly by James Martin at Oak Ridge National Laboratory and Roger Cole at Argonne National Laboratory.
