Full Description
Note 1: Use of the standard designation ISO 6944 refers to both ISO 6944:1985 and ISO 6944-1:2008.
1.1 These test methods evaluate the fire-resistive metallic HVAC duct system's fire resistance and fire-engulfment with horizontal and vertical through-penetration firestops.
Note 2: The intent of these test methods is to provide authorities having jurisdiction a means to evaluate the fire performance of HVAC duct systems to enable their application and use.
1.2 These test methods evaluate the fire performance of HVAC ducts, including both supply (pressurized: Condition A - Horizontal and Condition B - Vertical) and return (exhaust: Condition C - Horizontal and Condition D - Vertical).
1.3 These test methods evaluate the ability of a HVAC duct system to resist the spread of fire from one compartment to other compartments separated by a fire resistance rated construction when the HVAC duct system is exposed to fire under one or more of the following conditions:
1.3.1 Condition A-Fire exposure from the outside of the horizontal HVAC duct system without openings,
1.3.2 Condition B-Fire exposure from the outside of the vertical HVAC duct system without openings,
1.3.3 Condition C-Fire exposure from the outside with hot gases entering the inside of the horizontal HVAC duct system with unprotected openings,
Note 3: Unprotected openings are openings that are not protected by fire dampers.
1.3.4 Condition D-Fire exposure from the outside with hot gases entering the inside of the vertical HVAC duct system with unprotected openings.
1.4 These test methods provide a means for determining the fire-resistance of vertical and horizontal HVAC duct systems, when subjected to the standard time-temperature curve of Test Methods E119.
1.4.1 Condition A-These test methods provide a means for evaluating a horizontal HVAC duct system, without openings exposed to fire, passing through a vertical fire-separating element.
1.4.2 Condition B-These test methods provide a means for evaluating a vertical HVAC duct system, without openings exposed to fire and outfitted with a horizontal connection, passing through a horizontal fire-separating element.
1.4.3 Condition C-These test methods provide a means for evaluating a horizontal HVAC duct system, with unprotected openings exposed to fire, passing through a vertical fire-separating element.
1.4.4 Condition D-These test methods provide a means for evaluating a vertical HVAC duct system with a horizontal connection, and with unprotected openings exposed to fire, passing through a horizontal fire-separating element.
1.5 These test methods prescribe a standardized fire exposure for comparing the test results of the fire resistive materials and HVAC duct systems. The results of these tests are one factor in assessing predicted fire performance of HVAC duct systems. Using these test results to predict the performance of actual HVAC duct systems requires the evaluation of test conditions.
1.6 The values stated in inch-pound units are to be regarded as the standard. The SI valu
