32、tp:/.D6113 1124. Summary of Test Method4.1 All fire-test-response characteristics in this test method are determined using the apparatus and procedures described in TestMethod E1354. See also 9 and 10.4.2 The oxygen consumption principle, used in this test method, is based on the observation that, g

33、enerally, the net heat ofcombustion is directly related to the amount of oxygen required for combustion (1).10Approximately 13.1 MJ of heat are releasedper 1 kg of oxygen consumed. Test specimens in this test method are burned in ambient air conditions, while being subjected toa prescribed external

34、heating flux. (See also X5.1).4.3 The heat release is determined by the measurement of the oxygen consumption, as determined by the oxygen concentrationand the flow rate in the combustion product stream, as described in Test Method E1354.4.4 The primary measurements are oxygen concentration and exha

35、ust gas flow rate. Additional measurements include the timeto sustained flaming, the smoke obscuration generated, the mass loss rate, and the effective heat of combustion. Ignitability isdetermined by measuring the time from initial exposure to time of sustained flaming of the test specimen.4.5 A co

36、ne calorimeter is used to measure the consumption of oxygen during this test; heat release is then calculated, based onthe oxygen consumption principle. The test specimen is mounted horizontally and a spark ignition source is employed.5. Significance and Use5.1 This test method is used to determine

37、the heat release rate and a number of other fire-test-response characteristics as a resultof exposing insulating materials contained in electrical or optical cables to a prescribed heating flux in the cone calorimeterapparatus.5.2 Quantitative heat release measurements provide information that is po

38、tentially useful for design of electrical or opticalcables, and product development.5.3 Heat release measurements provide useful information for product development by giving a quantitative measure of specificchanges in fire performance caused by component and composite modifications. Heat release d

39、ata from this test method will notbe predictive of product behavior if the product will not spread flame over its surface under the fire exposure conditions of interest.5.4 The fire-test-response characteristics determined by this test method are affected by the thickness of the material used as tes

40、tspecimen, whether as a plaque or as coating on a wire or cable. The diameter of the wire or cable used will also affect the testresults.5.5 A radiant exposure is used as an energy source for this test method. This type of source has been used for comparison withheat release rate and flame spread st

41、udies of insulating materials constructed into cables when burning in a vertical cable trayconfiguration (Test Methods D5424 and D5537) (2-9). No definitive relationships have been established.5.6 The value of heat release rate corresponding to the critical limit between propagating cable fires and

42、non-propagating firesis not known.5.7 This test method does not determine the net heat of combustion.5.8 It has not been demonstrated that this test method is capable of predicting the response of electrical or optical fiber cablesin a full scale fire. In particular, this test method does not addres

43、s the self-extinguishing characteristics of the cables in a full scalefire.6. Test Limitations6.1 If during the test of one or more of the three replicate test specimens, any of the following unusual behavior occurs: moltenmaterial overflows the specimen holder trough; a test specimen is displaced f

44、rom the zone of controlled irradiance (explosivespalling); or the test specimen swells sufficiently prior to ignition to touch the spark plug or swells up to the plane of the heaterbase during combustion; then test an additional specimen of the identical preconditioned test specimens in the test mod

45、e in whichthe unusual behavior occurred. Do not incorporate data obtained from the tests noted above, yielding inadequate results, in theaveraged data but report the occurrence. This test method is not suitable if more than three out of six test specimens tested showany of the above characteristics.

46、6.2 The applicability of this test method to smoldering ignition of cables has not been demonstrated. This test method is notsuitable for incident heat fluxes below 10 kW/m2.6.3 The validity of the results of this test method for a particular scenario depends on the conditions under which the tests

47、areconducted. In particular, it has been established that the use of a different heating flux will change relative results.7. Safety Precautions7.1 The test procedures involve high temperatures and combustion processes. Hazards therefore exist for burns, ignition ofextraneous objects or clothing, an

48、d inhalation of combustion products. The operator must take appropriate precautions during theinsertion and removal of the test specimens, for example, by using protective gloves. Do not touch either the cone heater or theassociated fixtures while hot, except with the use of appropriate protective g
