Summary

< div style=" text-align:left " class=" NoteLevel1" >

< span class=" note cdone" style=" text-transform: uppercase " > Note 1:< / span> & #x00a0 < span class=" note cdone" > Use of the standard designation ISO 6944 refers to both ISO 6944:1985 and ISO 6944-1:2008.< / span>

< / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.1< / span> & #x00a0 These test methods evaluate the fire-resistive metallic HVAC duct system& #x2019 s fire resistance and fire-engulfment with horizontal and vertical through-penetration firestops.

< div style=" text-align:left " class=" NoteLevel1" >

< span class=" note cdone" style=" text-transform: uppercase " > Note 2:< / span> & #x00a0 < span class=" note cdone" > 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.< / span>

< / div> < / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.2< / span> & #x00a0 These test methods evaluate the fire performance of HVAC ducts, including both supply (pressurized: Condition A & #x2013 Horizontal and Condition B & #x2013 Vertical) and return (exhaust: Condition C & #x2013 Horizontal and Condition D & #x2013 Vertical).

< / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.3< / span> & #x00a0 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:

< div class=" SectionLevel3" > < p class=" subsec2 cdone2" > < span class=" Head4 cdone" > 1.3.1< / span> & #x00a0 < span class=" Head4Title cdone" > Condition A& #x2014 < / span> Fire exposure from the outside of the horizontal HVAC duct system without openings,

< / div> < div class=" SectionLevel3" > < p class=" subsec2 cdone2" > < span class=" Head4 cdone" > 1.3.2< / span> & #x00a0 < span class=" Head4Title cdone" > Condition B& #x2014 < / span> Fire exposure from the outside of the vertical HVAC duct system without openings,

< / div> < div class=" SectionLevel3" > < p class=" subsec2 cdone2" > < span class=" Head4 cdone" > 1.3.3< / span> & #x00a0 < span class=" Head4Title cdone" > Condition C& #x2014 < / span> Fire exposure from the outside with hot gases entering the inside of the horizontal HVAC duct system with unprotected openings,

< div style=" text-align:left " class=" NoteLevel2" >

< span class=" note cdone" style=" text-transform: uppercase " > Note 3:< / span> & #x00a0 < span class=" note cdone" > Unprotected openings are openings that are not protected by fire dampers.< / span>

< / div> < / div> < div class=" SectionLevel3" > < p class=" subsec2 cdone2" > < span class=" Head4 cdone" > 1.3.4< / span> & #x00a0 < span class=" Head4Title cdone" > Condition D& #x2014 < / span> Fire exposure from the outside with hot gases entering the inside of the vertical HVAC duct system with unprotected openings.

< / div> < / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.4< / span> & #x00a0 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 < span class=" Body-link1 cdone" > E119< / span> .

< div class=" SectionLevel3" > < p class=" subsec2 cdone2" > < span class=" Head4 cdone" > 1.4.1< / span> & #x00a0 < span class=" Head4Title cdone" > Condition A& #x2014 < / span> 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.

< / div> < div class=" SectionLevel3" > < p class=" subsec2 cdone2" > < span class=" Head4 cdone" > 1.4.2< / span> & #x00a0 < span class=" Head4Title cdone" > Condition B& #x2014 < / span> 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.

< / div> < div class=" SectionLevel3" > < p class=" subsec2 cdone2" > < span class=" Head4 cdone" > 1.4.3< / span> & #x00a0 < span class=" Head4Title cdone" > Condition C& #x2014 < / span> 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.

< / div> < div class=" SectionLevel3" > < p class=" subsec2 cdone2" > < span class=" Head4 cdone" > 1.4.4< / span> & #x00a0 < span class=" Head4Title cdone" > Condition D& #x2014 < / span> 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.

< / div> < / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.5< / span> & #x00a0 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.

< / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.6< / span> & #x00a0 The values stated in inch-pound units are to be regarded as the standard. The SI values given in parentheses are for information only, unless the SI units are used consistently to perform all of the test methods referenced herein. In this case, the SI units will be regarded as the standard and will be used in Section < span class=" Body-link1 cdone" > 13< / span> , Report.

< / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.7< / span> & #x00a0 The text of these test methods references notes and footnotes which provide explanatory material and (excluding those in tables and figures) shall not be considered as requirements of the fire-test-response standard.

< / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.8< / span> & #x00a0 This document specifically excludes evaluating ducts that carry combustibles, flammable vapors, combustible gases, and commercial kitchen ventilation systems commonly called grease ducts or hazardous exhaust ducts, which are tested in compliance with Test Methods < span class=" Body-link1 cdone" > E2336< / span> .

< / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.9< / span> & #x00a0 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.

< / div> < div class=" SectionLevel2" > < p class=" caveat cdone2" > < span class=" Head3 cdone" > 1.10< / span> & #x00a0 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

< / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.11< / span> & #x00a0 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
