Significance and Use4.1 The oxygen consumption principle, used for the mea-surements described here, is based on the observation that,generally, the net heat

27、 of combustion is directly related to theamount of oxygen required for combustion (1).7Approxi-mately 13.1 MJ of heat are released per 1-kg of oxygenconsumed. Test specimens in the test are burned in ambient airconditions, while being subjected to a prescribed externalheating source.4.1.1 This techn

28、ique is not appropriate for use on its ownwhen the combustible fuel is an oxidizer or an explosive agent,which release oxygen. Further analysis is required in suchcases (see Appendix X2).4.2 The heat release is determined by the measurement ofthe oxygen consumption, as determined by the oxygen con-c

29、entration and the flow rate in the combustion product stream,in a full scale environment.4.3 The primary measurements are oxygen concentrationand exhaust gas flow rate. Additional measurements includethe specimen ignitability, the smoke obscuration generated, thespecimen mass loss rate, the effectiv

30、e heat of combustion andthe yields of combustion products from the test specimen.4.4 The oxygen consumption technique is used in differenttypes of test methods.

The room shall haveno openings other than a doorway opening 0.76 m 6 6mmby2.03 m 6 6 mm (30 by 80 in.), located as indicated in Fig. 1,and other small op

39、enings, as necessary to make test measure-ments. Construct the test room of wooden or metal studs, andline it with gypsum wallboard, Type X, or calcium silicatewallboard. Position a hood (see Section 6) outside of the roomdoorway, such that it collects all the combustion gases. Thereshall be no obst

40、ructions to the air supply to the test setup.NOTE 2Both Type X gypsum wallboard and calcium silicate wall-board with a thickness of 12.7 mm (0.5 in.) have been found acceptable.If the wallboard is thicker, it will not affect the results of this test. Gypsumwallboard is likely to generate a measurabl

41、e amount of heat or smokerelease at high heat inputs, due primarily to its paper facer.5.1.2.1 Install an additional layer of fire rated wallboard onthe portions of the walls or ceiling directly adjacent to the testspecimen location. Cover at least 1.22 by 1.22 m (4 by 4 ft) ofthe ceiling with the a

42、dded wallboard, but do not place anadditional layer of wallboard under the test specimen. Thisceiling surface is the most severely exposed to flames and heatand needs frequent replacement. Replace any portion of thelining if cracks occur or severe burn damage is observed.5.1.2.2 Frequently, whenever

43、 there is a single test specimen,such as Test Method E 1537, Test Method E 1590, or TestMethod E 1822, the test specimen location is the corner of theroom furthest away from the doorway. The test specimen alsois usually placed on a weighing platform. This test room isunsuitable for Test Method D 542
