16、zed.4.2 The temperature of the hot surface is measured/controlled with a thermocouple and the heat transmitted by thetest specimen is measured with a copper calorimeter. Thecalorimeter temperature increase is a direct measure of the heatenergy received.4.3 A contact pressure of 3 kPa (0.5 psi) is us

17、ed to comparematerial performance under controlled conditions. If a differentpressure is chosen to represent a specific use condition, whereit is used should be noted under test conditions (13.1.2.3).4.4 The material performance is determined from theamount of heat transferred by the specimen and th

18、e observedeffect of the heat exposure on the specimen. The thermalprotection is the exposure time required to cause the accumu-lated heat received by the sensor to equal the heat that willresult in a pain sensation (see Table 1) or cause a second degreeburn in human tissue (see Table 2), as predicte

19、d from compari-son of heat transfer data with human tissue heat tolerancecurves (see Table 1 and Table 2).5. Significance and Use5.1 This test method rates materials intended for use asprotective clothing against exposure to hot surfaces, for theirthermal insulating properties and their reaction to

20、the testconditions.5.2 The thermal protection time as determined by this testmethod relates to the actual end-use performance only to thedegree that the end-use exposure is identical to the exposureused in this test method; that is, the hot surface test temperatureis the same as the actual end-use t

21、emperature and the testpressure is the same as the end-use pressure.5.2.1 Higher pressures, beyond the 3 kPa (0.5 psi) pressureprovided by the calorimeter assembly in this test method shallbe permitted to be used in this test method to simulate theconditions of protective clothing use.5.3 The proced

22、ure maintains the specimen in a static,horizontal position under a standard pressure and does notinvolve movement.5.4 One of the intended applications for this test method iscomparing the relative performance of different materials.5.5 This test method is limited to short exposure because themodel u

23、sed to predict burn injury is limited to predictions oftime-to-burn for up to 30 seconds, and predictions of time-to-pain for up to 50 seconds. The use of this test method for longerhot surface exposures requires a different model for determin-ing burn injury or a different basis for reporting test

Apparatus6.1 General ArrangementThe arrangement of the indi-vidual components of the test apparatus is shown in Fig. 1.6.1.1 Alternatively, transmit temperature output readings toa data acquisition unit, then computer process to obtain the testresult.6.2 Hot PlateShall have a flat heated

25、surface with thesmallest dimension, a minimum of at least 200 mm (8 in.) andhave the ability to achieve a temperature of at least 371C(700F) and to permit temperature control within 2.8C(65F).6.3 Surface plate The flat plate shall be 6.4 mm (14 in.)thick, 140 by 140 mm (5.5 by 5.5 in.) wide, with a

26、2.4 mm (332in.) hole drilled from the edge to the center of the plate (Fig. 2).Use either electrolytic copper or T-1100 aluminum surfaceplates. The surface plate must be flat, smooth, and free frompits and cavities. (Flatness is indicated by negligible lightpassing between a straight edge and the pl

27、ate surface.) Loss ofthe original mill finish (as judged with the naked eye) orwarping, or both, may result in failure to achieve calibrationwith the reference standard.6.4 SensorA copper calorimeter mounted in an insulatingblock with added weight and constructed as shown in Figs. 3and 4 with the st
