It needs to also be secured versus warm gasses and flame. It has to additionally pass the time-temperature test of ASTM E 119 or UL 263. The duct needs to additionally pass penetration testing under a positive pressure differential of 0.01 inch (2.49 Pa) and be continuous to the outside of the building.

Course 3 duct

SMACNA air duct layout standards specify that the course of the piping system must meet the Seal Course C or greater. This puts on all cases except for variable volume air ducts. STV stands for typical building and construction category of variable volume air ducts. For other stress classes and also their details, see S1.9. In enhancement to S1.9, the SMACNA High Stress Manual also specifies duct seal needs. In many cases, the course of the air duct have to match the design pressure class.

Span Type RE 3 is one of the most common design of Course 3. It is a double-walled duct with a perforated inner wall that must abide with the SMACNA building standards. The inner wall of the duct need to have a diameter of one-half inch and a span of one inch. The outer wall of the duct must have 2 vanes, one for each and every sided of the air duct The double-wall duct has a perforated outer wall surface as well as a layered fiberglass insulation on the inside.

Class 5 air duct
