Summary of Test Method4.1 This fire-test-response test method determines a number of fire-test-response characteristics associated with a stack of fivestacking chairs, ignited with a propane gas burner. Measurements to be made include the rate of heat and smoke release, totalam

25、ount of heat released, rates and concentrations of carbon oxides released, and rates and amounts of mass of test specimen lost.Other optional measurements are also described.4.2 In Test Configurations A and B, the test specimen is placed on a weighing platform located in a test room. An exhaust hood

26、,connected to a duct, is located at the doorway of the room.4.3 In Test Configuration C, the test specimen is placed on a weighing platform located directly under a hood.4.4 Heat, smoke, and combustion gas release instrumentation is placed in the duct.3 Available from International Organization for

Significance and Use5.1 This test method provides a means of measuring a variety of fire-test-response characteristics resulting from burning a stackof five stacking chairs. After i

30、gnition using a propane gas burner, the test specimen is permitted to burn freely under well-ventilatedconditions. The most important fire-test-response characteristic measured in this test method is the rate of heat release, whichquantifies the intensity of the fire generated.5.2 The rate of heat r

31、elease is measured by the principle of oxygen consumption. Annex A3 discusses the assumptions andlimitations.5.3 This test method also provides measures of other fire-test-response characteristics, including smoke obscuration (as the rateof smoke release, total smoke released or optical density of s

32、moke), combustion gas release (as concentrations of combustiongases), and mass loss, that are important to making decisions on fire safety.5.4 In the majority of fires, the most important gaseous components of smoke are the carbon oxides present in all fires. Theyare indicators of the toxicity of th

33、e atmosphere and of the completeness of combustion. Measurement of concentrations of carbonoxides are useful for two purposes: as part of fire hazard assessment calculations and to improve the accuracy of heat-releasemeasurements. Other toxic combustion gases, which are specific to certain materials

34、, are also indicators of the toxicity of theatmospheres, but are less crucial for determining combustion completeness and are optional measures; however fire hazardassessment often requires their measurement.5.5 The type of ignition chosen (flaming source) is common in both accidental and intentiona

35、l fires in public occupancies. Thistest method is thus applicable to stacked chairs in public occupancies. Such facilities include, but are not limited to, health-carefacilities, old-age convalescent and board and care homes, college dormitories and residence halls, and hotels and motels.5.6 One of

36、the following three configurations is to be used in this test method:5.6.1 Test Configuration AA test room with the following dimensions: 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 following dimensions: 3.66 by 3.05 by 2.44 m high (12 by 10 by 8 ft).

37、5.6.3 Test Configuration CAn open calorimeter (or furniture calorimeter).5.7 Rooms of other dimensions are acceptable where it has been shown that equivalent test results are obtained.5.8 Measurements in the three test configurations listed in 5.6 have been shown to give similar results for heat rel

38、ease in theduct and mass loss up to a rate of heat release of 600 kW (1).85.9 Measurements of temperatures, gas concentrations, and smoke obscuration in the room are dependent on room size.5.10 Studies on the flammability performance of furniture indicate that bench-scale fire tests are useful for p

39、reliminaryevaluations of component materials for substitution purposes (see Appendix X2).5.11 Limitations:5.11.1 This test method is not applicable to ignition by cigarettes or by any other smoldering source.5.11.2 The ignition source in this test method is a flaming source. Moreover, this particula

40、r ignition source has been shown tobe able to provide a distinction among different kinds of stacked chairs. However, the fraction of actual flaming stacked chair firesoccurring with ignitions more or less intense than that used here is not known.5.11.3 It is not known whether the results of this te

41、st method will be equally valid when stacking chairs are burned underconditions different from those specified. In particular, it is unclear whether the use of a different ignition source, the same ignitionsource but having a different duration of flame exposure, or a different gas-flow rate will ch

42、ange the results.5.11.4 The value of rate of heat release corresponding to the critical limit between propagating fires and nonpropagating firesis not known.5.11.5 As yet, there is not a known direct correlation between smoke obscuration or smoke toxicity measurements in the exhaustduct and overall

43、fire hazard.6.
