Smacna air duct leakage test manual.
Both the 2009 and 2012 iecc require duct tightness to be verified For duct leakage testing, the standard pressure used is 25 pascals, which is close to the operating pressure of a typical duct system This means that when we measure, say, 120 cubic feet per minute of duct leakage at 25 pascals (written 120 cfm25), that number is a pretty good estimate of how much air leaks out of the duct system while it's. It can generate up to 150l/s of airflow and test up to 2500pa static pressure.
The cobra model duct leakage tester is a great all around tester It can test 90 to 95% of the jobs you'll encounter Standard unit has digital gauges and panel mounted variable speed controller. This article will explain how to test for air duct leakage and describe the different types of ductwork to help you determine which tools to use.
