NC-2009 IEQp2:Environmental Tobacco Smoke (ETS) Control

ANSI/ASTM-E779-03 vs E779-10

For Mid-rise residential buildings it is required to perform a blower door test according E779-03 but international ASTM web site indicates that this standard has been superseded by ASTM E779-10. Some one knows which is the difference between them and why this information has not been updated in the USGBc web site at credit library section?. Thanks so much!

Hi Maria, I don't know how the standard may have changed but since E779-03 is referenced specifically in the rating system language, that would be the safer standard to follow. But there may be good reason to use the updated standard and if you wanted to do that I would submit a project specific CIR to get clearance before conducting the testing.
