1、Designation:E60307 Designation: E603 12An 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

2、revision. A number 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 issu

3、es that should be 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.

4、 Whether it is a single- 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 pe

5、rformance in full-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 mo

6、del.The various results 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 ad

The guide i

9、e performance under actual fire conditions.1.3.1 The results of experiments conducted in accordance with this guide are also useful elements for making regulatorydecisions regarding fire safety requirements. The use for regulatory purposes of data obtained from experiments conducted usingthis guide

10、requires that certain conditions and criteria be specified by the regulating authority.1.4 The rationale for conducting room fire experiments in accordance with this guide is shown in 1.5-1.81.5 Room fire experiments are a means of generating input data for computer fire models and for providing out

11、put data withwhich to compare modeling results.1.6 One of the major reasons for conducting room fire experiments is as an experimental means of assessing the potential firehazard associated with the use of a material or product in a particular application. This should be borne in mind when designing

12、nonstandard experiments.1.7 A rationale for conducting room fire experiments is the case when smaller-scale fire tests inadequately represent end-useapplications.1.8 A further rationale for conducting room fire experiments is to verify the results obtained with smaller scale tests, tounderstand the

13、scaling parameters for such tests.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 the response of materials, products, or assemblies to heat and flame under1This guide is under t

It does, however, set down many of the considerations for such a test,for example, room size and shape, ventilation, specimen description, ignition source,

35、instrumentation, and safety considerationsthat must be decided on in the design of a room fire experiment. It discusses performance criteria for the particular array offinishing and furnishing products that comprise the room. The behavior of any particular product in the room depends on the otherpro

36、ducts and materials present and how they are arranged in relation to one another.4.2 Whether a particular arrangement simulates the evaluation desired depends on the size and location of the ignition source.It is therefore important that the ignition source simulate, insofar as possible, an initiati

37、ng fire for the desired scenario.4.3 The main criterion suggested in this guide for evaluating fire performance is based on the time to flashover as indicated bythe time at which the radiation flux at the center of the floor exceeds 20 kW/m2. Other suggested indicators of flashover includean average

38、 upper air temperature in excess of 600C and the ignition of a cotton indicator. Other possible performance criteriainclude the total amount or rate of smoke and heat production, extent of the flame spread for a low-energy ignition source, andsize of the primary ignition source required to produce f

39、lashover.4.3.1 Where multi-room experiments are being conducted, flashover may not be an appropriate performance criteria. In fact, theexperiments may have to be conducted beyond flashover. Post-flashover is usually required in the test room in order to observehigh levels of toxic gases and smoke in

40、 remote rooms or flame spread in adjoining surface areas. Other performance criteria couldbe the levels of combustion products that impair visibility and cause incapacitation or lethality in remote rooms.4.4 Primary ignition sources include gas burners, wood cribs, waste containers, and pools of liq

41、uid fuel. Waste containers andwood cribs have the advantage of presenting a solid fuel fire with some feedback effects and a luminous flame that appears tosimulate the burning of furniture. However, the gas burner is the best choice for most fire experiments because of itsreproducibility. The placem

42、ent of the ignition source depends on the desired effect on the target material.4.5 The instrumentation for measuring burning rate, heat release rate, heat flux, temperature, upper layer depth, air velocity,flame spread, smoke, and gas concentration is discussed, along with suggested locations. A mi

43、nimum level of instrumentation isalso 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 (0.80 by2.0-m high) should be located in one wall, probably in one of the shorter ones. The top of the doorway should be at least 0.4 m16

44、 in. down from the ceiling to partially contain smoke and hot gases.4.7 Insofar as possible, the construction details of the wall and ceiling, as well as any enclosed insulation, should duplicate theroom being simulated. Boundary surfaces that do not form the specimen should also be constructed of m

45、aterials consistent withthe room being simulated (see 6.2.3).4.8 The safety of observers and the crew extinguishing the fire is emphasized strongly in this guide.4.9 The analysis of data should include a comparison of the critical times, heat fluxes, temperatures, heat release rate, and smokegenerat

46、ion in the room with ignition, flame spread, and smoke properties of the specimen materials. This would aid in thedevelopment or modification of small-scale tests and would provide useful information for assisting in the development ofanalytical room fire models.5. Significance and Use5.1 This guide

47、 provides assistance for planning room fire tests. The object of each experiment is to evaluate the role of amaterial, product, or system in the fire growth within one or more compartments.5.2 The relationship between laboratory fire test methods and actual room fires can be investigated by the use

48、of full-scale andreduced-scale experiments. This guide is aimed at establishing a basis for conducting full-scale experiments for the study of roomfire growth.5.3 Room fire tests can be placed into four main categories: reconstruction, simulation, research and standardization.5.3.1 Reconstruction ro

49、om fire tests are full scale replicates of a fire scene with the geometry, materials, contents, and ignitionsource intended to duplicate a particular scenario. The usual purpose of such a test is to evaluate what happened or what mighthappen in such a scenario.E603 1235.3.2 Simulation room fire tests are comparable to reconstruction fire tests, except that not all of the parameters are duplicated.A simulated fire test is one in which one or more components of a fire scenario are altered, usually in order to facilitate conductingthe test. The compartment design must
