Summary of Test Method4.1 The test method evaluates the protective performance ofthe materials of constructi

25、on and design of the test specimen,which is either a garment or an ensemble. The test specimen isplaced on an adult-size manikin at ambient atmosphericconditions and exposed to a laboratory flash fire simulationwith controlled heat flux, duration, and flame distribution. Thetest procedure, data acqu

26、isition, results calculations, and prepa-ration of the test report are performed with computer hardwareand software programs. Heat, which is transferred through thetest specimen during and after the exposure, is measured bysensors. These measurements are used to calculate the second-degree, third-de

27、gree, and total burn injury areas resulting fromthe flash fire exposure. Identification of the test specimen, testconditions, comments and remarks about the test purpose, andresponse of the test specimen to the exposure are recorded andare included as part of the report. The performance of the tests

28、pecimen is indicated by the calculated burn injury area and theway the specimen responds to the test exposure.5. Significance and Use5.1 This test method can be used to measure and comparethe thermal protection provided by different materials, gar-ments, clothing ensembles, and systems.5.2 This test

29、 method provides a measurement of garmentand clothing ensemble performance on a stationary uprightmanikin.5.2.1 This test method is not intended to be a qualityassurance test.5.2.2 The effects of body position and movement are notaddressed in this test method.5.3 The measurement of the thermal prote

30、ction provided byclothing is complex and dependent on the apparatus andtechniques used. It is not practical in a test method of this scopeto establish details sufficient to cover all contingencies. Depar-tures from the instructions in this test method may lead tosignificantly different test results.

31、 Technical knowledge con-cerning the theory of heat transfer and testing practices isneeded to evaluate if, and which, departures from the instruc-tions given in this test method are significant. Standardizationof the test method reduces, but does not eliminate, the need forsuch technical knowledge.

32、 Any departures should be reportedwith the results.6. Apparatus6.1 Instrumented ManikinAn upright manikin that is inthe shape and size of an adult male human form shall be used.(see Fig. 1)6.1.1 Size and ShapeThe manikin shall be constructedwith a head, chest/back, abdomen/buttocks, arms, hands, leg

33、s,and feet. The manikins dimensions should correspond to thoserequired for standard sizes of garments because deviations in fitwill affect the results. A male manikin consisting of the sizesgiven in Table 1 has been found satisfactory to evaluategarments or protective ensembles.6.1.2 The manikin sho

34、uld be constructed of flame resistant,thermally stable, nonmetallic materials.6.2 Apparatus for Burn Injury Assessment:6.2.1 Manikin ConstructionAt least 100 heat sensors shallbe distributed as uniformly as possible in each area on themanikin as given in Table 2.6.2.2 Heat sensor constructionEach he

35、at sensor shallhave the capacity to measure the incident heat flux over a rangefrom 0.0 to 4.0 cal/cm2s (167 kW/m2). This range permits theuse of the sensors to set the exposure level by directly exposingthe manikin to the flames in a test without the garment and alsohaving the capability to measure

36、 the heat transfer to themanikin with exposure of the test garment or protectiveclothing ensemble.6.2.2.1 The sensors shall be constructed of a material withknown thermal characteristics that can be used to indicate heatflux and temporal variation received by the sensors. The outerF1930002surface sh

37、all be covered with a thin layer of flat black hightemperature paint. The minimum response time for the sensorsshall be # 0.1 s.6.2.2.2 The calibration constants determined in 10.2.1.4 foreach sensor shall be recorded, and the most recent calibrationresults used to carry out the burn injury analysis

38、.6.3 Heat Flux Calibration SensorA device5, which istraceable to the National Institute of Standards and Technology(NIST), for measuring heat flux directly and accurately.6.4 Data Acquisition SystemA system shall be providedwith the capability of acquiring and storing the results of themeasurement f

39、rom each sensor at least once per 0.5 s for thedata acquisition period.6.5 Burn Assessment ProgramA computer software pro-gram that has the capability of receiving the output of thesensors, calculating the heat flux, and predicting the burn injurylevel at each sensor, and the total predicted burn in

40、jury area asa result of the thermal exposure shall be utilized (seeAnnexA1and Annex A2).6.5.1 Incident Heat CalculationThe incident heat shall bedetermined with exposure to the nude manikin by a computersoftware program. The value reported is the average of the areaweighted averages for each of the

41、sensors covered by the testgarment for the exposure duration.6.5.2 Burn Injury CalculationThe time predicted to causesecond-degree and third-degree burn injury for each sensorshall be calculated.6.5.3 Burn Injury AssessmentThe sum of the areas repre-sented by the sensors that received sufficient hea

42、t to result in acalculated second-degree burn shall be the second-degreepercentage burn area assessment. The sum of the area repre-sented by the sensors that received sufficient heat to result in acalculated third-degree burn shall be the third-degree percent-age burn area assessment. The sum of the

43、se two areas shall bethe total percentage burn injury assessment resulting from theexposure to the flash fire condition.6.6 Exposure ChamberA ventilated, fire-resistant enclo-sure with viewing windows and access door(s) shall beprovided to contain the manikin and exposure apparatus.6.6.1 Chamber Siz

44、eThe chamber size shall be sufficient toprovide a uniform flame exposure over the surface of the testgarment and shall have sufficient space to allow safe movementaround the manikin for dressing without accidentally jarringand displacing the burners. A chamber with minimum interiordimensions of 7.0

45、by 7.0 by 8.0 ft (2.1 by 2.1 by 2.4 m) hasbeen found satisfactory.6.6.2 Chamber Air FlowThe unaided air flow within thechamber shall be sufficient to permit the combustion processneeded for the required heat flux during the exposure time andshall be controlled to provide a quiet atmosphere for the d

46、ataacquisition period, and the forced air exhaust system shall besufficient for rapid removal of combustion gas products afterthe data acquisition period.
