Oriflow provides two test sheets for duct leakage and duct pressurization tests. They are time-saving tools for the calculation of duct surface area, allowable leakage, as well as airflow across orifice plate and pass/fail criteria. One sheet is for jobs requiring use of SMACNA Leakage Class, while the other is for projects specifying DW/143 Pressure Class.
