If the m

This standard test method provides a means for measuring, inbench scale, fire-test-response c

Summary of Test Method4.1 This test method is based on the observation that, generally, the net heat of combustion is directly related to the amount ofoxygen required for combustion (1).5Approximately 13.1 3 103kJ of energy are released as heat for each kg of oxygen consumed.Specimen
27、s in the test are burned in ambient air conditions, while being subjected to a prescribed external heating flux 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
28、 described in Test Method E1354.4.3 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 dete
29、rmined by measuring the time for initial 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 met
30、hod is identical to that in Test Method E1474, except for the slashing of the surface of thespecimen prior to testing.2For referenced ASTM standards, visit the ASTM website, www.astm.org, or contact ASTM Customer Service at serviceastm.org.

Significance and Use5.1 This test method provides a means to determine various fire-test-response characteris
33、tics, including the time to sustainedflaming and the heat release rate, of composites exposed to a prescribed heat flux in the cone calorimeter apparatus, after they havebeen vandalized in a prescribed manner, to expose the filling material.5.2 It is clearly impossible to predict the manner in which
34、 a mattress or furniture will be vandalized. The objective of this testmethod is to develop 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
35、 provide information which is useful for product design and product development,for mattresses 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 c
36、aused by component and composite modifications. Heat release data from this method will not 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 investigatio
37、n of the variation in response between the system asdesigned by the manufacturer and the way 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 o
38、r upholstered furniture)with the required fire-test-response characteristics for the scenario 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
39、touch the spark plug or swells up to the plane of the heater baseduring combustion.5.7.2 This 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/m inci
40、dent flux). Ithas been shown that this source models well, for furniture composites, a full scale source equivalent to five sheets of newspaper(2). It has also been shown that upholstered furniture and mattresses, particularly in public occupancies, are, on occasion, involvedin fires after exposure
41、to flaming ignition sources, However, it is not known what fraction of actual flaming mattress or furniturefires 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 condit
42、ions differentfrom the specified ones. In particular, it is unclear whether the use of a different ignition source, or the same ignition source butat a different incident heat flux, will change relative results.5.7.5 The value of heat release rate corresponding to the critical limit between propagat
43、ing mattress fires and non-propagatingmattress fires is not 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, namel
44、y investigate theeffect of the exposed filling material on the fire-test-response characteristics of the composite.6. Apparatus6.1 Use the apparatus described in Test Method E1354, also known as the cone calorimeter, for this test.7. Safety Precautions7.1 These test procedures involve high temperatu
45、res 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 specimens. The operator must refrain fromtouching eit
46、her 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 foam-cutting blade. This blade has no teeth. Inste
47、ad, 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; theref
48、ore, 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 3 98 3 50 mm. Each of these dimensions must be controlled to 60.5 mm. As the material f
49、or the formingblocks, use a dense wood, such as maple, which is minimally subject to dimensional changes when the humidity is changed. Donot use pine. Use only fully kiln-dried timber for making the forming blocks. Ensure that all surfaces are cut straight and true andare smooth. Do not round the edges but slightly round the corners. It is preferable to lacquer the blocks with an acrylic lacquerto ensure a hard, smooth, stable surface. Make up a minimum of 12 blocks to allow a reasonable number of specimens to beprepared at the same time.F1550 1038.1.3 AdhesiveSe
