Description / Abstract: SMACNA HVAC LEAKAGE TEST, 2nd Edition, - HVAC AIR DUCT LEAKAGE TEST MANUAL. FOREWORD. SMACNA first published a procedure for leakage testing of so-called medium and high pressure ductwork since January It appeared in Chapter 10 of the high velocity (later high pressure) construction standards and in Chapter 8. The HVAC Air Duct Leakage Test Manual provides practical and detailed procedures for conducting leakage tests. Apparent differences of about ten percent between fan delivery and sum of airflow measurements at terminals do not necessarily mean poor sealing and excess leakage. Potential accuracy of flow measurements should be evaluated.
