(2006)DISCUSSIONThis usually draws more air into the fire. (2006)combustible, adjcapable of undergoing combu
38、stion. (1985)DISCUSSIONThe term combustible is often delimited to specificfire-exposure conditions. For example, building materials are consid-ered combustible if they are capable of undergoing combustion in air atpressures and temperatures that might occur during a fire in a building.Similarly, som
39、e materials that are not combustible under such condi-tions may be combustible when exposed to higher temperatures andpressures or to an oxygen-enriched environment. Materials that are notcombustible in bulk form may be combustible in finely divided form.(1985)combustion, na chemical process of oxid

(See also glow and smolder-ing. ) (1989)combustion products, neffluent produced when a materialundergoes combustion (see also smoke; see also combus-tion). (2001)DISCUSSIONThe combustion pr
41、ocess releases effluents that havemass, in gaseous, liquid, or solid form, and generates radiant energy, asheat or light, and sometimes sound. However, the common usage of theterm combustion products in ASTM E05 standards is only for thosewhich have mass. (2001)composite, nstructured combination of

(2008)effective heat of combustion, nthe amount of heat generatedper unit mass lost by a material, product or assembly, whenexposed to specific fire test conditions (contrast gross heatof co
43、mbustion) (2003).DISCUSSIONThe effective heat of combustion depends on the testmethod and is determined by dividing the measured heat release by themass loss during a specified period of time under the specified testconditions. Typically, the specified fire test conditions are provided bythe specifi
44、cations of the fire test standard that cites effective heat ofcombustion as a quantity to be measured. For certain fire testconditions, involving very high heat and high oxygen concentrationsunder high pressure, the effective heat of combustion will approximatethe gross heat of combustion. More ofte
45、n, the fire test conditions willrepresent or approximate certain real fire exposure conditions, and theeffective heat of combustion is the appropriate measure. Typical unitsare kJ/g or MJ/kg.

(See also firehazard, fire risk, and fire-test-response characteristic.)(1993)DISCUSSIONAn array of fire-test-response characteristics in a set ofdata relevant to the assessment of

In other words, all the fire tests used would have a demon-strated validity for the fire scenario in question, for example by havingcomparable fire intensities.
