Joints and seams shall with either the IMC ·International Mc�chanical Code or IRC • International Residenti;il Code, as applicable. R403.3.3 Duct testing (Mandatory). Ducts shall be pressure tested to determine air leakage by one of the following methods. 1: Rough-In Test: Total leakage shall be measured with a pressure differential of 0.1 inch w.g. (25 Pa) across the system, including the manufacturer air handlers enclosure if installed at the time of th<➔ test. All registers shall be taped or otherwise sealed during the test. 2: Post-construction test: Total leakage shall be measured with a pressure differential of 0.31 inch w.g. (25 PA) across the system, including the manufacturer air handlers enclosure if installed at the time of the test. All registers shall be taped or otherwise sealed during the test. Exception: Duct air leakage test shall not be required where the dlicts .ind .iir handlers are located within the building thermal envelop�?. A written report of the results of the test shall be �igned by the conducting the test and provided to the code official. R403.3.4 Duct leakage (Prescriptive) The total leakage of the ducts. were measured in accordance with Section R403.3.3, shall follow: l: Rough-in test. The total leakage shall be less than or equal to 4 cubic feet per minute (113.3 l/min.) per 100 square feet (9.29 m2) of conditioned floor area where the air handlEar is installed at the time of the test. Where the air handler is not installed at the time of the test, the total leakage shall be less than or equal to 3 ctibic feet per minute� (85 l/min) per 100 square feet {9.29 m2) of conditioned floor area. 2: Post-construction test: Total leakage shall be less than or equal to 4 cubic feet per minute (113.3 L/min) per 100 square feet (92.9 m2) of conditioned floor area. R403.3.5 Building cavities (Mandatory). Building framing cavities shall not be used as ducts or plenum's. No Panning of wall cavities for supply or return ducts & plenum's.
