Terminology3.1 For definitions of terms used in this test method use thefollowing documents. For terms related

18、to textiles refer toTerminology D123, for terms related to protective clothingrefer to Terminology F1494 and for terms related to bodydimensions refer to Terminology D5219.3.2 Definitions:3.2.1 burn injury, nthermal damage which occurs tohuman skin at various depths and is a function of localtempera

19、ture and time.3.2.1.1 DiscussionBurn injury in human tissue occurswhen the tissue is heated above a critical temperature (44C(317.15 K) or 111F). Thermal burn damage to human tissuedepends on the magnitude of the temperature rise above thecritical value and the duration that the temperature is above

20、 thecritical value. Thus damage can occur during both the heatingand cooling phases of an exposure. The degree of burn injury(second or third degree) depends on the maximum depth withinthe skin layers to which tissue damage occurs. The first-degreeburn injury is considered minor relative to second-d

21、egree andthird-degree burn injuries. It is not included in the evaluation oftest specimens in this test method (see Appendix X1).3.2.2 fire exposure, nin the fire testing of clothing, the fireexposure is a propane-air diffusion flame with a controlled heatflux and spatial distribution, engulfing the

22、 manikin for acontrolled duration.3.2.2.1 DiscussionThe flames are generated by propanejet diffusion burners. Each burner produces a reddish-orangeflame with accompanying black smoke (soot).3.2.3 flame distribution, nin the fire testing of clothing, aspatial distribution of incident flames from burn

23、ers to providea controlled heat flux over the surface area of the manikin.3.2.4 heat flux, nthe heat flow rate through a surface ofunit area perpendicular to the direction of heat flow (kW/m2)(cal/scm2).3.2.4.1 DiscussionTwo different heat fluxes are referred toin this test method: incident and abso

24、rbed. The incident heatflux refers to the energy striking the nude manikin, or theexterior fo the test specimen when mounted on the manikin,during flame engulfment. The absorbed heat flux refers to onlythe portion of the incident heat flux which is absorbed by eachthermal energy sensor based on its

25、absorption characteristics.The incident heat flux is used in setting the required exposureconditions while the absorbed heat flux is used in calculatingthe predicted skin burn injury.3.2.5 instrumented manikin, nin the fire testing ofclothing, a structure designed and constructed to represent anadul

26、t-size human and which is fitted with thermal energy (heatflux) sensors on its surface.3.2.5.1 DiscussionThe manikin is fabricated to specifieddimensions from a high temperature resistant material (see6.1). The instrumented manikin used in fire testing of clothingis fitted with at least 100 thermal

27、energy sensors, distributedover the manikin surface. The feet and hands are not normallyfitted with sensors. If the feet and hands are equipped withsensors, it is up to the user to define a procedure to interpret theresults.3.2.6 predicted second-degree burn injury, na calculatedsecond-degree burn i

28、njury to skin based on measurementsmade with a thermal energy sensor.3.2.6.1 DiscussionFor the purposes of this standard, pre-dicted second-degree burn injury is defined by the burn injurymodel parameters (see Section 12 and Appendix X1). Somelaboratories assign an area to each sensor over which the

29、 sameburn injury prediction is assumed to occur, others do not.3.2.7 predicted third-degree burn injury, na calculatedthird-degree burn injury to skin based on measurements madewith a thermal energy sensor.3.2.7.1 DiscussionFor the purposes of this standard, pre-dicted third-degree burn injury is de

30、fined by the burn injurymodel parameters (see Section 12 and Appendix X1). Somelaboratories assign an area to each sensor over which the sameburn injury prediction is assumed to occur, others do not.3.2.8 predicted total burn injury, nin the fire testing ofclothing, the manikin surface area represen

33、thermal inertia ofhuman skin and some do not. The known sensors in current usehave relatively small detection areas. An assumption is madefor the purposes of this method that thermal energy measuredin these small areas can be extrapolated to larger surroundingsurface areas so that the overall maniki

34、n surface can beapproximated by a minimum number of sensors. The resultingsensor predicted burn injury applies to the extrapolated cover-age area. Some laboratories assign different coverage areas toeach sensor over which the same burn injury prediction isassumed to apply, others do not (see 6.2.2.1

Summary of Test Method4.1 This test method covers quantitative measurements andsubjective o

39、bservations that characterize the performance ofsingle layer garments or protective clothing ensemblesmounted on a stationary upright instrumented manikin. Theconditioned test specimen is placed on the instrumentedmanikin at ambient atmospheric conditions and exposed to apropane-air diffusion flame

40、with controlled heat flux, flamedistribution and duration. The average incident heat flux is 84kW/m2(2 cal/scm2) with durations up to 20 seconds.4.2 The test procedure, data acquisition, calculation ofresults and preparation of parts of the test report are performedwith computer hardware and softwar

41、e programs. The complex-ity of the test method requires a high degree of technicalexpertise in the test setup and operation of the instrumentedmanikin and the associated data collection and analysis soft-ware.4.3 Thermal energy transferred through and from the testspecimen during and after the expos

42、ure is measured by thermalenergy sensors located at the surface of the manikin. Acomputer based data acquisition system is used to store thetime varying output from the sensors over a preset timeinterval.4.4 Computer software uses the stored data to calculate theincident heat flux and the absorbed h

43、eat flux and their variationwith time for each sensor. The calculated absorbed heat fluxand its variation with time is used to calculate the temperaturewithin human skin and subcutaneous layers (adipose) as afunction of time. The temperature history within the skin andsubcutaneous layers (adipose) i

44、s used to predict the onset andseverity of human skin burn injury. The computer softwarecalculates the predicted second-degree and predicted third-degree burn injury and the total predicted burn injury resultingfrom the exposure.4.5 The overall percentage of predicted second-degree,predicted third-d

45、egree and predicted total burn injury is calcu-lated by dividing the total number of sensors indicating each ofthese conditions by the total number of sensors on the manikin.Alternately, the overall percentages are calculated using sensorarea weighted techniques for facilities with non-uniform senso

46、rcoverage. A reporting is also made of the above conditionswhere the areas that are not covered by the test specimen areexcluded (see 13.5.1 and 13.5.2). This test method does notinclude the 12 % of body surface area represented by theunsensored manikin feet and hands. No corrections are appliedfor

47、their exclusion.4.6 The visual and physical changes to the test specimen arerecorded to aid in understanding overall performance and howthe resulting burn injury results can be interpreted.4.7 Identification of the test specimen, test conditions,comments and remarks about the test purpose, and respo

48、nse ofthe test specimen to the exposure are recorded and are includedas part of the report.4.8 The performance of the test specimen is indicated by thecalculated burn injury area, expressed as a percentage, andsubjective observations of material response to the test expo-sure.4.9 Appendix X1 contain

49、s a general description of humanburn injury, its calculation and historical notes.5. Significance and Use5.1 Use this test method to measure the thermal protectionprovided by different materials, garments, clothing ensembles,and systems when exposed to a specified fire (see 3.2.2, 3.2.3,4.1, and 10.4).5.1.1 This test method does not simulate high radiantexposures, for example, those found in electric arc flashexposures, some types of fire exposures where liquid or solidfuels are involved, nor exposure to nuclear explosions.5.2 This test method provides a
