CHANTILLY, Va. — The Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA) announced that the American National Standards Institute (ANSI) has approved its HVAC Air Duct Leakage Test Manual, second edition, as an American National Standard.
SMACNA said the new manual covers revised leakage criteria and builds on the methods for testing ductwork for air leaks contained in the first edition. A new chapter written specifically for designers and specifiers was added to help reduce some of the misunderstandings related to duct leakage and the methods of testing.
