2、, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice deals with methods to construct, calibrate,and use full scale oxygen consumption calorime
3、ters to helpminimize testing result discrepancies between laboratories.1.2 The methodology described herein is used in a numberof ASTM test methods, in a variety of unstandardized testmethods, and for research purposes. This practice will facilitatecoordination of generic requirements, which are not

Other fire-test-response characteristics also are deter-mined.1.4 This practi

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 of combustion is directly related to theamount of oxygen required for combustion (1).7Approxi-mately 13.1 MJ of heat ar
28、e 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 technique is not appropriate for use on its ownwhen the combustible fuel is an oxidizer or an explosive agent,which release o
29、xygen. 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-centration and the flow rate in the combustion product stream,in a full scale environment.4.3 The primary measurements ar
30、e oxygen concentrationand exhaust gas flow rate. Additional measurements includethe specimen ignitability, the smoke obscuration generated, thespecimen mass loss rate, the effective heat of combustion andthe yields of combustion products from the test specimen.4.4 The oxygen consumption technique is
31、 used in differenttypes of test methods. Intermediate scale (Test Method E 1623,UL 1975) and full scale (Test Method D 5424, Test MethodD 5537, Test Method E 1537, Test Method E 1590, TestMethod E 1822, ISO 9705, NFPA 265, NFPA 266, NFPA 267,NFPA 286, UL 1685) test methods, as well as unstandardized

A large test specimen is placedeither under the hood or inside the room. This practice isinte
35、nded to address issues associated with equipment requiringa large instrumented hood and not stand-alone test apparatuseswith small test specimens.4.4.1 Small scale test methods using this technique, such asTest Methods D6113, E 1354, E 1474 and E 1740, as well as,ISO 5660 internationally, are based
36、on a stand-alone apparatus,wherein a small specimen is tested within the equipment.4.5 Throughout this practice, test equipment is referenced toprovide helpful guidance to test facilities. Substitution ofequivalent, or better, test measuring devices is permissible.5. Test Room Layout5.1 Standard Roo
37、ms:5.1.1 Three standard room configurations have been incommon use for many years, often designated as the “ASTM”/“ISO” room (cited in Guide E 603 and in ISO 9705), and the“California” room (used in CATB 129 and CATB 133, as wellas, Test Methods E 1537, E 1590, and E 1822), and the cabletray test ro
38、om (used in Test Methods D 5424 and D 5537,aswell as, in UL 1685).5.1.2 ASTM/ISO RoomThe test room shall have interiordimensions of 2.44 m 6 25 mm by 3.66 m 6 25 mm by 2.44m 6 25 mm high (8 by 12 by 8 ft high). The room shall haveno openings other than a doorway opening 0.76 m 6 6mmby2.03 m 6 6 mm (
39、30 by 80 in.), located as indicated in Fig. 1,and other small openings, 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
40、that it collects all the combustion gases. Thereshall be no obstructions 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
41、 of this test. Gypsumwallboard is likely to generate a measurable 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. Co
42、ver at least 1.22 by 1.22 m (4 by 4 ft) ofthe ceiling with the added 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 occu
43、r or severe burn damage is observed.5.1.2.2 Frequently, whenever 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 weig
44、hing platform. This test room isunsuitable for Test Method D 5424 or Test Method D 5537.The test method indicates test specimen location.5.1.2.3 When testing surface linings (walls or ceilings),weighing of the test specimen during the test is usually notpractical. Mass loss during testing, if desire
45、d, must be esti-mated from calculations.5.1.3 California RoomThe test room shall have dimen-sions of 3.05 m 6 25 mm 3 3.66 m 6 25 mm 3 2.44 m 6 25mm high (10 by 12 by 8 ft high). The room shall have noopenings other than a doorway opening 0.97 m 6 6mm3 2.06m 6 6 mm (38 by 81 in.), located as indicat

47、 gases. There shall be noobstructions to the air supply to the test set-up.NOTE 3Both 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 lik

Cover at least 1.22 by 1.22 m (4 by
49、4 ft) ofthe ceiling with the added 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.5.1.3.2 This test room commonly is used for furnituretesting only. Usually, the test specimen is located in a cornerand placed on a weighing platform.
