The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has published three new standards on hvac air ducts, cool storage systems, and measuring refrigerant flow rates.
ANSI/ASHRAE/SMACNA Standard 126-2000, “Methods of Testing Hvac Air Ducts,” can be used to determine hvac air duct structural strength, dimensional stability, durability, and leakage characteristics, said Herman Behls, chair of the committee that wrote the standard. Tests simulate structural stresses and conditions that ductwork will see in service.
