If the mattress or f

Summary of Test Method4.1 This test
30、method is based on the observation that, generally, the net heat of combustion is directly related to the amount ofoxygen required for combustion (1).5 Approximately 13.1 103 kJ of energy are released as heat for each kg of oxygen consumed.Specimens in the test are burned in ambient air conditions,
31、while being subjected to a prescribed external heating initial test heatflux of 35 kW/m2.4.2 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 E1354.4.3
32、 The primary measurements are oxygen concentration and exhaust gas flow rate, used to calculate heat release. Additionalmeasurements include the mass loss rate of the specimen, the time to sustained flaming, and the effective heat of combustion.Ignitability is determined by measuring the time for in
33、itial exposure to time of sustained flaming of the specimen.4.4 In order to simulate vandalism, the outer layers of the composite to be tested are cut across the surface, in the form of anX, to expose the interior filling material.4.5 The procedure in this test method is identical to that in Test Me
34、thod E1474, except for the slashing of the surface of thespecimen prior to testing.5. Significance and Use5.1 This test method provides a means to determine various fire-test-response characteristics, including the time to sustainedflaming and the heat release rate, of composites exposed to a prescr
35、ibed initial test heat flux in the cone calorimeter apparatus, afterthey have been vandalized in a prescribed manner, to expose the filling material.5.2 It is clearly impossible to predict the manner in which a mattress or furniture will be vandalized. The objective of this testmethod is to develop
36、data indicating the effect of violating the integrity of the fabric (or fabric-interliner) protection and exposingthe padding to the source of heat (see Appendix X3).5.3 Quantitative heat release measurements provide information which is useful for product design and product development,for mattress
37、es or furniture destined for correctional occupancies.5.4 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 data from this method will not
38、bepredictive of product behavior if the product will not spread flame over its surface under the fire exposure conditions of interest.5.5 The use of test specimens simulating vandalism allows the investigation of the variation in response between the system asdesigned by the manufacturer and the way
39、 the system is occasionally present in actual use, with the filling material exposed to theincident energy.5.6 This test method allows alternative strategies to be employed for producing a product (mattress or upholstered furniture)with the required fire-test-response characteristics for the scenari
40、o under consideration.5.7 Limitations:5.7.1 The test data are invalid if any of the events in 5.7.1.1 or 5.7.1.2 occur.5.7.1.1 Explosive spalling.5.7.1.2 The specimen swells sufficiently prior to ignition to touch the spark plug or swells up to the plane of the heater baseduring combustion.5.7.2 Thi
41、s test method is not applicable to ignition by cigarettes, or by any other smoldering source.5.7.3 The ignition source in this test method is a radiant energy source of relatively high intensity (35 kW/m2 incident initialtest heat flux). It has been shown that this source models well, for furniture
42、composites, a full scale source equivalent to five sheetsof newspaper (2). It has also been shown that upholstered furniture and mattresses, particularly in public occupancies, are, onoccasion, involved in fires after exposure to flaming ignition sources, However, it is not known what fraction of ac
43、tual flamingmattress or furniture fires occur with ignitions more or less intense than the one modeled here.5.7.4 It is not known whether the results of this test method will be equally valid when it is carried out under conditions differentfrom the specified ones. In particular, it is unclear wheth
44、er the use of a different ignition source, or the same ignition source butat a different incident initial test heat flux, will change relative results.5.7.5 The value of heat release rate corresponding to the critical limit between propagating mattress fires and non-propagatingmattress fires is not
45、known.5.7.6 It is not known what fraction of the vandalism that occurs is represented by the prescribed model used in this standard.However, the method described here is adequate to address one of the major objectives of the standard, namely investigate theeffect of the exposed filling material on t
46、he fire-test-response characteristics of the composite.5 The boldface numbers in parentheses refer to the list of references at the end of this standard.F1550 1636. Apparatus6.1 Use the apparatus described in Test Method E1354, also known as the cone calorimeter, for this test.7. Safety Precautions7
47、.1 These test procedures involve high temperatures and combustion processes. Therefore, there is a potential hazard for burns,ignition of extraneous objects or clothing, and for inhalation of combustion products.7.2 The operator must use protective gloves for insertion and removal of the test specim
48、ens. The operator must refrain fromtouching either the cone heater or the associated fixtures while hot, except with the use of protective gloves.8. Test Specimen Preparation (Method A)8.1 Equipment and Supplies for Specimen Preparation (3):8.1.1 Cutting EquipmentCut foams with a band saw. Use a foa
49、m-cutting blade. This blade has no teeth. Instead, it has a wavyscallop to the edge. Ensure that the blade is well sharpened, and make certain that no silicones or other oils are applied to lubricatethe blade. Lubrication must be solely with graphite or molybdenum compounds. The band saw blade must make a straight and truecut of the foam; therefore, set the blade guide no higher than 12 mm above the stock to be cut.8.1.2 Forming BlocksThe specimen preparation rests crucially upon the proper use of forming blocks. These blocks are madein dimensions of 98 98
