Through our testing experience, it has been determined that the lower pressures within the specified range in ASTM E779 are more susceptible to error, due to wind and stack pressure effects that commonly occur in larger structures. Additionally, project specifications typically include whole building air testing performance criteria of a measured air leakage rate at a 75 Pa (not 60 Pa) pressure differential. When testing is limited to higher pressure ranges, induced pressure increments may be less than the increments specified in ASTM E779. The lowest pressure within the induced pressure range may be constrained by weather conditions where the highest pressure within the induced pressure range is typically limited by the fan capacity brought to the site. Ideal weather conditions are difficult to achieve when testing is scheduled weeks in advance. Thus, to achieve the most accurate data and meet the required performance criteria outlined in the project specification, testing is generally limited to smaller induced pressure ranges at higher pressures both above and below the required pressure differential (75 Pa).
