20、ry in human tissue occurs when the tissue is heated above a critical temperature (44C (317.15K) or 111F). Thermal burn damage to human tissue depends on the magnitude of the temperature rise above the critical value andthe duration that the temperature is above the critical value. The degree of burn
21、 injury (second or third degree) depends on themaximum depth within the skin layers to which tissue damage occurs. The first-degree burn injury is considered minor relativeto second-degree and third-degree burn injuries. It is not included in the evaluation of test specimens in this test method (see

Summary of Test Method4.1 This test method covers quantitative measurements and subjective observations that characterize the performance of singlelayer garments or protective clot
38、hing ensembles mounted on a stationary instrumented manikin. The conditioned test specimen isplaced on the instrumented manikin at ambient atmospheric conditions and exposed to a propane-air diffusion flame withcontrolled heat flux, flame distribution and duration. The average exposure heat flux is
39、84 kW/m2(2 cal/scm2) with durations upto 20 seconds.4.2 The test procedure, data acquisition, calculation of results and preparation of parts of the test report are performed withcomputer hardware and software programs. The complexity of the test method requires a high degree of technical expertise
40、in thetest setup and operation of the instrumented manikin and the associated data collection and analysis software.4.3 Thermal energy transferred through and from the test specimen during and after the exposure is measured by thermal energysensors. The sensors are located at the surface of the mani
41、kin. They are used to measure the thermal energy absorbed as a functionof time over a preset time interval. A computer based data acquisition system is used to store the time varying output from thesensors.4.4 Computer software uses the stored data to calculate the heat flux and its variation with t
42、ime at the surface of each sensor.The calculated heat flux and its variation with time at the surface is used to calculate the temperature within human skin andsubcutaneous layers (adipose) as a function of time. The temperature history within the skin and subcutaneous layers (adipose) isused to pre
43、dict the onset and severity of human skin burn injury. The computer software calculates the predicted second-degreeand predicted third-degree burn injury and the total predicted burn injury resulting from the exposure.4.5 The overall percentage of predicted second-degree, predicted third-degree and
44、predicted total burn injury is calculated bydividing the total number of sensors indicating each of these conditions by the total number of sensors on the manikin. Alternately,the overall percentages are calculated using sensor area weighted techniques for facilities with non-uniform sensor coverage
45、. Areporting is also made of the above conditions where the areas that are uncovered by the test specimen are excluded. This testmethod does not include the 12 % of body surface area represented by the unsensored manikin feet and hands. No correctionsare applied for their exclusion.4.6 The visual an
46、d physical changes to the test specimen are recorded to aid in understanding overall performance and how theresulting burn injury results can be interpreted.4.7 Identification of the test specimen, test conditions, comments and remarks about the test purpose, and response of the testspecimen to the
47、exposure are recorded and are included as part of the report.4.8 The performance of the test specimen is indicated by the calculated burn injury area and subjective observations of materialresponse to the test exposure.4.9 Appendix X1 contains a general description of human burn injury, its calculat
48、ion and historical notes.5. Significance and Use5.1 Use this test method to measure the thermal protection provided by different materials, garments, clothing ensembles, andsystems to a specified fire exposure (see 3.2.2, 4.1, 10.1.3, and 10.1.4).5.1.1 This test method does not simulate high radiant
49、 exposures, for example, those found in electric arc flash exposures, sometypes of fire exposures where liquid or solid fuels are involved, nor exposure to nuclear explosions.5.2 This test method provides a measurement of garment and clothing ensemble performance on a stationary upright manikinof specified dimensions. This test method is used to provide predicted skin burn injury for a specific garment or protective clothingensemble when exposed to a laboratory simulation of a fire. It does not establish a pass/fail for material performance.5.2.1 This test
