1、Designation: E603 12aAn American National StandardStandard Guide forRoom Fire Experiments1This standard is issued under the fixed designation E603; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number
2、 in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis guide has been written to assist those planning to conduct full-scale compartment fireexperiments. There are many issues that should be
3、resolved before such an experimental program isinitiated, and this guide is written with the objective of identifying some of these issues and presentingconsiderations that will affect each choice of procedure.This guide deals with any or all stages of fire growth in a compartment. Whether it is a s
4、ingle- ormulti-room experiment, observations can be made from ignition to flashover or beyond full-roominvolvement.One major reason for conducting research on room fires is to learn about the room fire buildupprocess so the results of standard fire test methods can be related to performance in full-
5、scale roomfires, allowing the further refinement of these test methods or development of new ones.Another reason concerns computer fire modeling. Full-scale tests can generate data needed formodeling. Comparisons of modeling with full-scale test results can serve to validate the model.The various re
6、sults among room fire tests reflect different experimental conditions. The intent of thisguide is to identify these conditions and discuss their effects so meaningful comparisons can be madeamong the room fire experiments conducted by various organizations.1. Scope1.1 This guide addresses means of c
7、onducting full-scale fireexperiments that evaluate the fire-test-response characteristicsof materials, products, or assemblies under actual fire condi-tions.1.2 It is intended as a guide for the design of the experimentand for the use and interpretation of its results. The guide isalso useful for es
8、tablishing laboratory conditions that simulatea given set of fire conditions to the greatest extent possible.1.3 This guide allows users to obtain fire-test-responsecharacteristics of materials, products, or assemblies, which areuseful data for describing or appraising their fire performanceunder ac
9、tual fire conditions.1.3.1 The results of experiments conducted in accordancewith this guide are also useful elements for making regulatorydecisions regarding fire safety requirements. The use forregulatory purposes of data obtained from experiments con-ducted using this guide requires that certain
10、conditions andcriteria be specified by the regulating authority.1.4 The rationale for conducting room fire experiments inaccordance with this guide is shown in 1.5-1.81.5 Room fire experiments are a means of generating inputdata for computer fire models and for providing output datawith which to com
11、pare modeling results.1.6 One of the major reasons for conducting room fireexperiments is as an experimental means of assessing thepotential fire hazard associated with the use of a material orproduct in a particular application. This should be borne inmind when designing nonstandard experiments.1.7
12、 A rationale for conducting room fire experiments is thecase when smaller-scale fire tests inadequately represent end-use applications.1.8 Afurther rationale for conducting room fire experimentsis to verify the results obtained with smaller scale tests, tounderstand the scaling parameters for such t
13、ests.1.9 Room fire tests can be placed into four main categories:reconstruction, simulation, research, and standardization.1.10 This standard is used to measure and describe theresponse of materials, products, or assemblies to heat andflame under controlled conditions, but does not by itself1This gu

It discusses performance criteria for the particulararray of finishing and
33、 furnishing products that comprise theroom. The behavior of any particular product in the roomdepends on the other products and materials present and howthey are arranged in relation to one another.4.2 Whether a particular arrangement simulates the evalua-tion desired depends on the size and locatio
34、n of the ignitionsource. It is therefore important that the ignition sourcesimulate, insofar as possible, an initiating fire for the desiredscenario.4.3 The main criterion suggested in this guide for evaluatingfire performance is based on the time to flashover as indicatedby the time at which the ra
35、diation flux at the center of the floorexceeds 20 kW/m2. Other suggested indicators of flashoverinclude an average upper air temperature in excess of 600Cand the ignition of a cotton indicator. Other possible perfor-mance criteria include the total amount or rate of smoke andheat production, extent
36、of the flame spread for a low-energyignition source, and size of the primary ignition sourcerequired to produce flashover.4.3.1 Where multi-room experiments are being conducted,flashover may not be an appropriate performance criteria. Infact, the experiments may have to be conducted beyondflashover.
37、 Post-flashover is usually required in the test room inorder to observe high levels of toxic gases and smoke in remoterooms or flame spread in adjoining surface areas. Otherperformance criteria could be the levels of combustion prod-ucts that impair visibility and cause incapacitation or lethalityin
38、 remote rooms.4.4 Primary ignition sources include gas burners, woodcribs, waste containers, and pools of liquid fuel. Waste con-tainers and wood cribs have the advantage of presenting a solidfuel fire with some feedback effects and a luminous flame thatappears to simulate the burning of furniture.
39、However, the gasburner is the best choice for most fire experiments because ofits reproducibility. The placement of the ignition source de-pends on the desired effect on the target material.4.5 The instrumentation for measuring burning rate, heatrelease rate, heat flux, temperature, upper layer dept
40、h, airvelocity, flame spread, smoke, and gas concentration is dis-cussed, along with suggested locations. A minimum level ofinstrumentation is also suggested.4.6 A typical compartment size is 2.4 by 3.7 m 8 by 12 ft,with a 2.4-m 8-ft high ceiling. A standard-size doorway (0.80by 2.0-m high) should b
41、e located in one wall, probably in oneof the shorter ones. The top of the doorway should be at least0.4 m 16 in. down from the ceiling to partially contain smokeand hot gases.4.7 Insofar as possible, the construction details of the walland ceiling, as well as any enclosed insulation, should dupli-ca
42、te the room being simulated. Boundary surfaces that do notform the specimen should also be constructed of materialsconsistent with the room being simulated (see 6.2.3).4.8 The safety of observers and the crew extinguishing thefire is emphasized strongly in this guide.4.9 The analysis of data should
43、include a comparison of thecritical times, heat fluxes, temperatures, heat release rate, andsmoke generation in the room with ignition, flame spread, andsmoke properties of the specimen materials. This would aid inthe development or modification of small-scale tests and wouldprovide useful informati
44、on for assisting in the development ofanalytical room fire models.5. Significance and Use5.1 This guide provides assistance for planning room firetests. The object of each experiment is to evaluate the role ofa material, product, or system in the fire growth within one ormore compartments.5.2 The re
45、lationship between laboratory fire test methodsand actual room fires can be investigated by the use offull-scale and reduced-scale experiments. This guide is aimedat establishing a basis for conducting full-scale experiments forthe study of room fire growth.5.3 Room fire tests can be placed into fou
46、r main categories:reconstruction, simulation, research and standardization.5.3.1 Reconstruction room fire tests are full scale replicatesof a fire scene with the geometry, materials, contents, andignition source intended to duplicate a particular scenario. Theusual purpose of such a test is to evalu
47、ate what happened orwhat might happen in such a scenario.5.3.2 Simulation room fire tests are comparable to recon-struction fire tests, except that not all of the parameters areduplicated. A simulated fire test is one in which one or morecomponents of a fire scenario are altered, usually in order to
48、facilitate conducting the test. The compartment design mustcarefully address geometry and materials of construction toensure that they do not significantly alter the fire response.Reconstruction and simulation fire tests often have a distinctiveobjective, such as time to flashover, that is related t
49、o the natureof the original fire scene.5.3.3 Research room fire tests are conducted in order toelucidate the effects of one or more of the following: geometry,materials, placement of items, ventilation, or other parameters.The measured effects (such as room temperature, heat flux,heat release rate, time to flashover, post flashover conditions)are chosen to provide the most useful information.5.3.4 Standardization room fire tests include scenarios thathave been adopted by a standardization body. In this case, thecompartment, ignition source, instrumentation and the natur
