ASHRAE’s Standard 62, “Ventilation for Acceptable Indoor Air Quality,” has generated a lot of controversy over the years. That controversy came to a climax when the ASHRAE board took the unprecedented step of placing the old standard (62-89) into continuous maintenance in June 1997. That meant the committee had to start back at square one, which it did in January 1998.
Thankfully, things have settled down a little since then. With the approval of four addenda in June 1999, the standard has been renamed 62-1999.
