21、e a critical temperature (44 C(317.15 K or 111 F). Thermal burn damage to human tissuedepends on the magnitude of the temperature rise above thecritical value and the duration that the temperature is above thecritical value. Thus, damage can occur during both the heatingand cooling phases of an expo

22、sure. 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-degree andthird-degree burn injuries. It is not included in the evaluation oftest specimens in

23、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 manikin for acontrolled duration.3.2.2.1 DiscussionThe flames are generated by propanejet dif

The incident heatflux refers to the energy striking the nude manikin, or theexterior of

26、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 absorption characteristics.The incident heat flux is used in setting the required exposurecond

The instrumented manikin used in fire testing of clothingis fitted with at least 100 thermal energy sensors, distributedover the manikin surface. The feet and hands are not normallyfitte

30、e purposes of this standard, pre-dicted second-degree burn injury is defined by the burn injurymodel parameters (see Section 12 and Appendix X1).

36、sed successfully include slug calorimeters, surface and buriedtemperature measurements, and circular foil heat flux gauges.Some types of sensors approximate the thermal inertia ofhuman skin and some do not. The known sensors in current usehave relatively small detection areas. An assumption is madef

37、or the purposes of this method that thermal energy measuredin these small areas can be extrapolated to larger surroundingsurface areas so that the overall manikin surface can beapproximated by a minimum number of sensors. The resultingsensor-predicted burn injury applies to the extrapolated cover-ag

Some laboratories assign different coverage areas toeach sensor over which the same burn injury prediction isassumed to apply; others, with equally spaced sensors, haveequal areas for each sensor (see 6.2.2.1).3.2.11 thermal protection, nthe property that characterizesthe overall performance

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

42、 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 with controlled

43、heat flux, flamedistribution, and duration. The average incident heat flux is84 kWm2(2 cal/scm2), with durations up to 20 s.4.2 The test procedure, data acquisition, calculation ofresults, and preparation of parts of the test report are performedwith computer hardware and software programs. The comp

44、lex-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 exposure is measured by t

45、hermalenergy 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 heat flux and their v

46、ariationwith 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) is used to predict th

47、e 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-degree, and predicted

48、 total burn injury iscalculated by dividing the total number of sensors indicatingeach of these conditions by the total number of sensors on themanikin. Alternately, the overall percentages are calculatedusing sensor area-weighted techniques for facilities with non-uniform sensor coverage.Areporting

This testmethod does not include the 12 % of body surface arearepresented by the unsensored manikin feet and hands. Nocorrections are applied for 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 te
