Summa

25、ry of Test Method4.1 The test method evaluates the protective performance ofthe materials of construction 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 f

26、ire simulationwith controlled heat flux, duration, and flame distribution. Thetest procedure, data acquisition, 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 th

27、e exposure, is measured bysensors. These measurements are used to calculate the second-degree, third-degree, 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 sp

28、ecimen to the exposure are recorded andare included as part of the report. The performance of the testspecimen 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 therm

29、al protection provided by different materials, gar-ments, clothing ensembles, and systems.5.2 This test 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 b

30、ody position and movement are notaddressed in this test method.5.3 The measurement of the thermal protection 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.

31、 Depar-tures from the instructions in this test method may lead tosignificantly different test results. 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. S

32、tandardizationof the test method reduces, but does not eliminate, the need forsuch technical knowledge. Any departures should be reportedwith the results.6.
