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 sh
3、ould 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. Whether i
4、t 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 performance
5、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 model.The va
6、rious 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 addresses mea
7、ns of conducting full-scale fire experiments that evaluate the fire-test-response characteristics ofmaterials, products, or assemblies under actual fire conditions.1.2 It is intended as a guide for the design of the experiment and for the use and interpretation of its results. The guide is alsousefu
8、l for establishing laboratory conditions that simulate a given set of fire conditions to the greatest extent possible.1.3 This guide allows users to obtain fire-test-response characteristics of materials, products, or assemblies, which are usefuldata for describing or appraising their fire performan
9、ce 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 requires th
10、at 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 output data wi
11、thwhich 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 designingnonstandard
12、 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 scaling par
13、ameters for such tests.1 This guide is under the jurisdiction of ASTM Committee E05 on Fire Standards and is the direct responsibility of Subcommittee E05.21 on Smoke and CombustionProducts.Current edition approved Aug. 1, 2012Aug. 1, 2013.

33、tical applications, this term is usually applied to tests where the item to be tested is larger than would fit in a bench-scaletest.4. Summary of Guide4.1 This guide does not define a standard room fire test. It does, however, set down many of the considerations for such a test,for example, room siz
34、e and shape, ventilation, specimen description, ignition source, 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 behav
35、ior of any particular product in the room depends on the otherproducts 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 th
36、at the ignition source simulate, insofar as possible, an initiating 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
37、 kW/mis often considered (for example in room-corner tests)the time from the start of test until any two 2. Other suggested indicators of flashover include an average upper air temperaturein excess of 600C and the ignition of a cotton indicator. Other possible performance criteria include the total
38、amount or rate ofsmoke and heat production, extent of the flame spread for a low-energy ignition source, and size of the primary ignition sourcerequired to produce flashover.of the following conditions have been attained:(1) The heat release rate exceeds 1 MW in a standard ASTM/ISO room (sixed 2.4 b
39、y 3.7 by 2.4 m; 8 by 12 by 8 ft). Thiscriterion is the first criterion used by room corner tests such as NFPA 286.(2) The heat flux on the compartment floor exceeds 20 kW/m2.(3) The average upper air temperature exceeds 600C.(4) Flames exit the compartment door.(5) Radiant heat ignition of a cellulo
40、sic (cotton or paper) indicator on the floor occurs.4.3.1 Other possible performance criteria indicating flashover include the total amount or rate of smoke and heat released, theextent of the flame spread for a low-energy ignition source, and the size of the primary ignition source required.4.3.2 W
41、here 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 remote rooms or
42、 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 liquid fuel. Waste
43、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 placement of the ignit
44、ion 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 minimum level of i
45、nstrumentation 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 in. down from t
46、he ceiling to partially contain smoke and hot gases.E603 1334.7 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 materials
47、 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 smokegeneration in t
48、he 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 provide
49、s 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 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.
