Hvac Air Duct Leakage Test

This american national standard ansi smacna 016 2012 covers revised leakage criteria and builds on the proven methods for testing ductwork for air leaks from the first edition.

Hvac air duct leakage test. So once you ve measured the amount of air moving through the fan you ve quantified the duct leakage at the test pressure. Hvac air duct leakage test manual order no. The hvac air duct leakage test manual provides practical and detailed procedures for conducting leakage tests. This means that when we measure say 120 cubic feet per minute of duct leakage at 25.

This american national standard ansi smacna 016 2012 covers revised leakage criteria and builds on the proven methods for testing ductwork for air leaks from the first edition. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow. Figure 5 1l from the 2012 smacna hvac air duct leakage test manual shows the allowable leakage as a function of duct leakage classification and static pressure in the duct. Leakage class can be calculated using equation 3 but needs to be specified if duct air leakage tests are required.

1972 2 nd edition 2012 122 pages. Potential accuracy of flow measurements should be evaluated. A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating ventilating and air conditioning hvac ductwork.
