Includes ANSI/ASHRAE addenda listed in Appendix O - Ventilation for Acceptable Indoor Air Quality

Abstract

This American National Standard (ANS) is a national voluntary consensus Standard developed under the auspices of ASHRAE.

Consensus is defined by the American National Standards Institute (ANSI), of which ASHRAE is a member and which has approved this Standard as an ANS, as “substantial agreement reached by directly and materially affected interest categories.

This signifies the concurrence of more than a simple majority, but not necessarily unanimity.

Consensus requires that all views and objections be considered, and that an effort be made toward their resolution.”

Compliance with this Standard is voluntary until and unless a legal jurisdiction makes compliance mandatory through legislation
