21、1 burn injury, nthermal damage which occurs to human skin at various depths and is a function of local temperature andtime.3.2.1.1 DiscussionBurn injury in human tissue occurs when the tissue is heated above a critical temperature (44C(44 C (317.15 K) or111F).111 F). Thermal burn damage to human tis
22、sue depends on the magnitude of the temperature rise above the critical valueand the duration that the temperature is above the critical value.Thus, damage can occur during both the heating and cooling phasesof an exposure. The degree of burn injury (second or third degree) depends on the maximum de

The first-degree burn injury is considered minor relative to second-degree and third-degree burn injuries.It is not included in the evaluation of test specimens in this test method (see Appendix X1).3.2.2 fire exposure, nin the fire testing of

37、sensors which have been used successfully include slug calorimeters, surface and buried temperature measurements, andcircular foil heat flux gauges. Some types of sensors approximate the thermal inertia of human skin and some do not. The knownsensors in current use have relatively small detection ar

An assumption is made for the purposes of this method that thermalenergy measured in these small areas can be extrapolated to larger surrounding surface areas so that the overall manikin surfacecan be approximated by a minimum number of sensors. The resulting sensor predicted sensor-predicted b

Some laboratories assign different coverage areas to each sensor over which the same burn injuryprediction is assumed to apply, others do not apply; others, with equally spaced sensors, have equal areas for each sensor (see6.2.2.1).3.2.11 thermal

Summar
43、y of Test Method4.1 This test method covers quantitative measurements and subjective observations that characterize the performance of singlelayer garments or protective clothing ensembles mounted on a stationary upright instrumented manikin. The conditioned testspecimen is placed on the instrumente
44、d manikin at ambient atmospheric conditions and exposed to a propane-air diffusion flamewith controlled heat flux, flame distribution, and duration. The average incident heat flux is 84 84 kWkW/mm2 (2cal/scmcal/scm2) with durations up to 20 seconds.s.4.2 The test procedure, data acquisition, calcula
45、tion 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 in thetest setup and operation of the instrumented manikin and the associated data collection and an
46、alysis software.4.3 Thermal energy transferred through and from the test specimen during and after the exposure is measured by thermal energysensors located at the surface of the manikin. A computer based computer-based data acquisition system is used to store the timevarying output from the sensors
47、 over a preset time interval.4.4 Computer software uses the stored data to calculate the incident heat flux and the absorbed heat flux and their variation withtime for each sensor.The calculated absorbed heat flux and its variation with time is used to calculate the temperature within humanskin and
48、subcutaneous layers (adipose) as a function of time. The temperature history within the skin and subcutaneous layers(adipose) is used to predict the onset and severity of human skin burn injury. The computer software calculates the predictedsecond-degree and predicted third-degree burn injury and th
49、e total predicted burn injury resulting from the exposure.4.5 The overall percentage of predicted second-degree, predicted third-degreethird-degree, and predicted total burn injury iscalculated by dividing the total number of sensors indicating each of these conditions by the total number of sensors on themanikin. Alternately, the overall percentages are calculated using sensor area weighted techniques for facilities with non-uniformnonuniform sensor coverage. A reporting is also made of the above conditions where the areas that are not covere
