Full Description

This is a reaffirmation of ASHRAE Standard 41.4-1996. 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.

The change made for the 2006 reaffirmation was that the name of the standard was added to the Table of Contents.
