Hazards7.1 WarningEven under the most carefully observedconditions, smoldering combustion can progress to a pointwhere it cannot be read

30、ily 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 the test area

31、.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 combustion.8. Te

32、st Specimen8.1 Specimen ConditioningCondition test samples, ciga-rettes, and sheeting material at a temperature of 73.4 6 9F(23 6 5C) and a relative humidity of 50 6 5 % for at least 24h immediately prior to testing. If the test room conditions donot meet the above specifications, then testing shall

33、 be initiatedwithin 10 min after the materials are removed from theconditioned room. The mock-up assembly shall be constructedin 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 in the pro

34、duction furniture.Construct the various parts of the mock-up as described in8.2-8.7. In all cases, the arrangement and thickness of uphol-stery material in the mock-up shall reproduce the constructiondetails of the production furniture being evaluated.8.3 Loose Seat CushionsMake seat cushions in the

35、 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 furnitureitem)

36、 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 Tight SeatIf

37、 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 horizontal pane

38、l 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 mock-up,

39、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 material andfa

40、sten 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 confine t

41、he 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 and Tops o

42、f 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 of0.5-in. (1.3-cm) thick ply

43、wood, 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-struction of production furniture.9. Procedure9.1 Assemble a mock-up test sample by attaching the side orback panels, or both, to the mock-up fr

44、ame and placing a seatcushion (either loose or tight seat construction) against thepanels, as shown in Fig. 3(b). Place the assembly on a table or(a) Armrest and Tops of Back and Seat Support System(b) Seat Cushion, Side, and BackFIG. 3 Upholstered Furniture Mock-Up TestE 1352 08a3platform in the te

45、st 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 ignitionresistance will

46、 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 cushio

47、nsurfaces (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 outermost edg

48、e 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 surface of

49、 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 covered
