Bibliography
This standard specifies requirements and test methods for strength and air leakage of circular ductwork used in air conditioning and ventilation systems in buildings. The standard is intended to establish the mechanical strength and leakage required to verify the fitness for the intended service as installed ductwork. The standard is primarily intended for in-situ measurements, but provisions are also made for its use in laboratory testing. The requirements and methods are applicable also to rectangular ductwork in respect of air leakage.
