Summary of Test Method4.1 This test method is used to evaluate the cigaretteignition resistance of uphol

19、stered furniture by exposingmock-up upholstered furniture assemblies to lighted cigarettesas an ignition source.5. Significance and Use5.1 This test method is intended to measure the performanceof upholstered furniture material assemblies under conditionsof exposure to smoldering cigarettes. This is

20、 accomplished bytesting furniture assemblies.5.2 This test method is recommended for upholstered fur-niture used in facilities such as hospitals, nursing homes,residential-custodial care and supervisory facilities, or in thepublic area of facilities such as educational, assembly, orresidential occup

21、ancies.5.3 This test method is not intended to measure the perfor-mance of upholstered furniture material assemblies underconditions of open-flame exposure, and does not indicatewhether the assemblies will resist the propagation of flameunder severe fire exposure or when tested in a manner thatdiffe

22、rs substantially from the test method.5.4 The results obtained with a material assembly tested inmock-up in accordance with this test method do not necessarilyindicate the performance of the same material assembly inother geometric configurations, such as in production furniture.6. Apparatus and Mat

23、erials6.1 Mock-upElements of the mock-up test jigs are illus-trated in Figs. 1 and 2. Fig. 3 shows the completed mock-upassemblies.6.2 The ignition source shall consist of SRM 1196 cigaretteswithout filter tips, made from natural tobacco 3.3 6 0.1 in.(83 6 2 mm) long with a tobacco packing density o

24、f0.156 6 0.012 oz/in.3(0.270 6 0.020 g cm3) and a totalweight of 0.039 6 0.004 oz (1.1 6 0.1 g). Standard ReferenceMaterial SRM 1196 is obtained from the National Institute ofStandards and Technology.6.3 Sheeting MaterialThe sheeting material to cover thetest cigarettes shall be 50 % cotton/50 % pol

The material shall be laundered in anautomatic home clothes washing machine and dried in a tumbledrier at least once before use. For testing, the sheeting materialshall be cut into pieces approximately 5 by 5 in. (

26、12.5 by 12.5cm).6.4 Test Area, equipped with a suitable system for exhaust-ing smoke and noxious gases produced during testing. The testshall be carried out in a draft protected area.

Hazards7.1 WarningEven under the most carefully observedconditions, smoldering combustion can progress to a pointwhere it c

30、annot be readily extinguished. It is imperative that atest be discontinued as soon as continuing combustion hasdefinitely occurred. Immediately wet the exposed area with awater spray from the water bottle, remove the charred orburned material, and immerse the material in a bucket of water.Ventilate

31、the test area.7.2 Products of combustion can be irritating and dangerousto test personnel. Test personnel must avoid exposure to smokeand gases produced during testing as much as possible. The useof a large hood with a low air velocity during testing isadvisable, as a means to remove products of com

32、bustion.8. Test Specimen8.1 Specimen ConditioningCondition test samples,cigarettes, and sheeting material at a temperature of73.4 6 9F (23 6 5C) and a relative humidity of 50 6 5%for at least 24 h immediately prior to testing. If the test roomconditions do not meet the above specifications, then tes

33、tingshall be initiated within 10 min after the materials are removedfrom the conditioned room. The mock-up assembly shall beconstructed in the conditioned area.8.2 GeneralProduce furniture mock-up by arranging up-holstery cover material and upholstery materials in the samesequence as they were used

34、in the production furniture.Construct the various parts of the mock-up as described in 8.2 8.7. In all cases, the arrangement and thickness of upholsterymaterial in the mock-up shall reproduce the constructiondetails of the production furniture being evaluated.8.3 Loose Seat CushionsMake seat cushio

35、ns in the samesize and manner and with the same material as productionfurniture. The cushion thickness shall be a maximum of 5 in.(13 cm).8.3.1 ExceptionUse cushions sized 25 by 22 in. (68 by 55cm) if actual cushion dimensions exceed these values.8.4 DecksPrepare decks (if they are part of the furni

36、tureitem) by attaching to the horizontal panel (Fig. 2(a) of the testapparatus the same materials in the same thickness as used inthe actual furniture construction. Stretch decking or upholsterycover material over the upholstery materials and securelyfasten to the underside of the wood panel.8.5 Tig

37、ht SeatIf the type of furniture item is constructedwith only tight seats, duplicate the seat for test in mock-up.Tight seat cushions shall be 18 6 2by226 2 in. (45 6 5by55 6 5 cm) and made of the same fabric and the samethickness used in production furniture. Attach the cushionassembly to the horizo

38、ntal panel of the test apparatus (see Fig.2(b) by extending the upholstery cover material around thepanel edges and fastening the cover material to the underside ofthe wood panel.8.6 Side and Back PanelsFurniture sides and backs shallbe mocked-up if, in the type of furniture to be represented bythe

39、mock-up, they are within 1 in. (2.5 cm) of a seat cushion.Make the mock-ups by upholstering one surface of the verticaltest panel (see Fig. 2(b) with the same upholstery material andupholstery cover material used in production furniture. Stretchthe upholstery cover material over the upholstery mater

40、ial andfasten to the back side of the framework. Cover all edges of thepanels with cover material. If the side and back construction ofthe furniture item are the same, only one vertical panel need beassembled and tested.8.7 BolstersBolsters resting on the seat cushion or sus-pended above it tend to

41、confine the heat from the cigarette andoften present a spatial arrangement different from the crevice.In such cases, prepare a mock-up bolster with dimensions to fitinto the mock-up arrangement and which presents to thecigarette the same spatial arrangement as in production furni-ture.8.8 Armrests a

42、nd Tops of BacksTest tops of armrests andback if (1) they present a surface large enough and so orientedas to support a cigarette and (2) if the construction differs inany way from the side-panel and back-panel constructions.Make tops of armrests and backs by upholstering a piece of(a) Armrest and T

43、ops of Back and Seat Support System(b) Seat Cushion, Side, and BackFIG. 3 Upholstered Furniture Mock-Up TestE1352 1630.5-in. (1.3-cm) thick plywood, approximately 12 by 20 in. (30by 50 cm) with the same materials used in the furniture item.The mock-up shall reproduce significant details of the con-s

44、truction of production furniture.9. Procedure9.1 Assemble a mock-up test sample by attaching the side orback panels, or both, to the mock-up frame and placing a seatcushion (either loose or tight seat construction) against thepanels, as shown in Fig. 3(b). Place the assembly on a table orplatform in

45、 the test area under an exhaust hood or other suitablemeans for exhausting the products of combustion from testing.Test separately the decks for loose cushion items, top ofarmrests, and backs. In some cases, the test to evaluateupholstered furniture material assemblies for cigarette ignitionresistan

46、ce will require two vertical panels, one seat cushion(loose or tight), one bolster, one deck, one top of armrest, andone top of back.9.2 Burn at least three cigarettes on each surface location(see Fig. 3(a) and (b). These locations include crevice(s)where seat cushion and vertical panels meet, seat

47、cushionsurfaces (including welt and smooth, quilted or tufted areas),top of upholstered arm rest, tops of upholstered back, and deck.9.3 For crevice locations, place the two cigarettes next to thecenter cigarette in the crevice so that their butt ends burn out atleast 3 in. (7.5 cm) from the outermo

48、st edge of the side of theback panel. Place the cigarettes horizontally. Place two of thethree cigarettes so that their entire length burns out against thewelt cord and the vertical panel surface. Place the thirdcigarette so that its entire length burns out against the welt cordand a horizontal surf

49、ace of the seat cushion.9.4 Each test cigarette shall be well-lighted and burned notmore than 0.16 in. (4 mm) when placed on a specific testlocation. After placement, cover each cigarette with a piece ofsheeting material. For crevice tests, pin one end of the sheetingmaterial to the vertical panels (approximately 2 in. (5 cm)above the cigarette) and drop the remaining material tocompletely cover the test cigarette. For all tests, ensure that agood sheeting material-to-cigarette contact is made by runningones finger across the full length of the
