Summary of Test Method4.1 This fire-test-response test method determines a numberof fire-test-response characteristics associated with a stack of

23、five stacking chairs, ignited with a propane gas burner. Mea-surements to be made include the rate of heat and smokerelease, total amount of heat released, rates and concentrationsof carbon oxides released, and rates and amounts of mass oftest specimen lost. Other optional measurements are alsodescr

24、ibed.4.2 In Test Configurations A and B, the test specimen isplaced on a weighing platform located in a test room. Anexhaust hood, connected to a duct, is located at the doorway ofthe room.4.3 In Test Configuration C, the test specimen is placed ona weighing platform located directly under a hood.4.

25、4 Heat, smoke, and combustion gas release instrumenta-tion is placed in the duct.4.5 Additional (optional) instrumentation placed in the testroom is also described.5. Significance and Use5.1 This test method provides a means of measuring avariety of fire-test-response characteristics resulting from

26、burn-ing a stack of five stacking chairs. After ignition using apropane gas burner, the test specimen is permitted to burnfreely under well-ventilated conditions. The most importantfire-test-response characteristic measured in this test method isthe rate of heat release, which quantifies the intensi

27、ty of the firegenerated.5.2 The rate of heat release is measured by the principle ofoxygen consumption.AnnexA3 discusses the assumptions andlimitations.5.3 This test method also provides measures of other fire-test-response characteristics, including smoke obscuration (asthe rate of smoke release, t

28、otal smoke released or opticaldensity of smoke), combustion gas release (as concentrationsof combustion gases), and mass loss, that are important tomaking decisions on fire safety.5.4 In the majority of fires, the most important gaseouscomponents of smoke are the carbon oxides present in all fires.T

29、hey are indicators of the toxicity of the atmosphere and of thecompleteness of combustion. Measurement of concentrationsof carbon oxides are useful for two purposes: as part of firehazard assessment calculations and to improve the accuracy ofheat-release measurements. Other toxic combustion gases,wh

30、ich are specific to certain materials, are also indicators of thetoxicity of the atmospheres, but are less crucial for determiningcombustion completeness and are optional measures; howeverfire hazard assessment often requires their measurement.5.5 The type of ignition chosen (flaming source) is comm

31、onin both accidental and intentional fires in public occupancies.This test method is thus applicable to stacked chairs in publicoccupancies. Such facilities include, but are not limited to,health-care facilities, old-age convalescent and board and carehomes, college dormitories and residence halls,

32、and hotels andmotels.5.6 One of the following three configurations is to be usedin this test method:5.6.1 Test Configuration AA test room with the followingdimensions: 3.66 by 2.44 by 2.44 m high (12 by 8 by 8 ft).5.6.2 Test Configuration BA test room with the followingdimensions: 3.66 by 3.05 by 2.

33、44 m high (12 by 10 by 8 ft).5.6.3 Test Configuration CAn open calorimeter (or furni-ture calorimeter).5.7 Rooms of other dimensions are acceptable where it hasbeen shown that equivalent test results are obtained.5Available from California Bureau of Home Furnishings and Thermal Insula-tion, State of

Box 22, SF-00341, Helsingfors, Finland.E18220725.8 Measurements in the three test configurations listed in5.6 have been shown to give similar results for heat release inthe

35、 duct and mass loss up to a rate of heat release of 600 kW(1).75.9 Measurements of temperatures, gas concentrations, andsmoke obscuration in the room are dependent on room size.5.10 Studies on the flammability performance of furnitureindicate that bench-scale fire tests are useful for preliminaryeva

36、luations of component materials for substitution purposes(see Appendix X2).5.11 Limitations:5.11.1 This test method is not applicable to ignition bycigarettes or by any other smoldering source.5.11.2 The ignition source in this test method is a flamingsource. Moreover, this particular ignition sourc

37、e has beenshown to be able to provide a distinction among different kindsof stacked chairs. However, the fraction of actual flamingstacked chair fires occurring with ignitions more or less intensethan that used here is not known.5.11.3 It is not known whether the results of this test methodwill be e

38、qually valid when stacking chairs are burned underconditions different from those specified. In particular, it isunclear whether the use of a different ignition source, the sameignition source but having a different duration of flameexposure, or a different gas-flow rate will change the results.5.11

39、.4 The value of rate of heat release corresponding to thecritical limit between propagating fires and nonpropagatingfires is not known.5.11.5 As yet, there is not a known direct correlationbetween smoke obscuration or smoke toxicity measurements inthe exhaust duct and overall fire hazard.6.
