28、graduatedin inches or millimeters in110 or116-in. divisions.7. Hazards7.1 WarningEven under the most carefully observedconditions, smoldering combustion can progress to a pointwhere it cannot be readily extinguished. It is imperative that atest be discontinued as soon as continuing combustion hasdef

29、initely 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.7.2 Products of combustion can be irritating and dangerousto test personnel. Test personnel must avo

30、id exposure to smokeand gases produced during testing as much as possible. A largehood with a low air velocity may be in operation during testingto remove products of combustion.8. Test Specimen8.1 Specimen ConditioningCondition test samples, ciga-rettes, and sheeting material at a temperature of 73

31、.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 be initiatedwithin 10 min after the materials are removed from theconditioned room. The mock-up assembly shall be co

32、nstructedin 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 production furniture.Construct the various parts of the mock-up as described in8.2-8.7. In all cases, the arrangement an

33、d 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 samesize and manner and with the same material as productionfurniture. The cushion thickness shall be a maximum of 5

34、 in.(13 cm).8.3.1 ExceptionCushions 25 by 22 in. (68 by 55 cm) maybe used if actual cushion dimensions exceed these values.8.4 DecksPrepare decks (if they are part of the furnitureitem) by attaching to the horizontal panel (Fig. 2(a) of the testapparatus the same materials in the same thickness as u

35、sed 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 the type of furniture item is constructedwith only tight seats, duplicate the seat for test in mock-up.Tight seat

36、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 panel of the test apparatus (see Fig.2(b) by extending the upholstery cover material around thepanel edges and fastenin

37、g 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, they are within 1 in. (2.5 cm) of a seat cushion.Make the mock-ups by upholstering one surface of the verticaltest

38、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 andfasten to the back side of the framework. Cover all edges of thepanels with cover material. If the side and back cons

39、truction 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 the heat from the cigarette andoften present a spatial arrangement different from the crevice.In such cases, prepare

40、 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 of BacksTest tops of armrests andback if (1) they present a surface large enough and so orientedas to support a ciga

41、rette 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 plywood, approximately 12 by 20 in. (30by 50 cm) with the same materials used in the furniture item.The mock-up shall

42、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 frame and placing a seatcushion (either loose or tight seat construction) against thepanels, as shown in Fig. 3(b). P

43、lace 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 023platform in the test area under an exhaust hood or other suitablemeans for exhausting the products of combustion from testing.Test sep

44、arately the decks for loose cushion items, top ofarmrests, and backs. The test to evaluate upholstered furniturematerial assemblies for cigarette ignition resistance may re-quire two vertical panels, one seat cushion (loose or tight), onebolster, one deck, one top of armrest, and one top of back.9.2

45、 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 cushionsurfaces (including welt and smooth, quilted or tufted areas),top of upholstered arm rest, tops of upholstered back, and deck.9.

46、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 edge of the side of theback panel. Place the cigarettes horizontally. Place two of thethree cigarettes so that their entire length b

47、urns 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 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

48、 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, e

49、nsure that agood sheeting material-to-cigarette contact is made by runningones finger across the full length of the covered cigarette.9.5 To test a seat cushion (either loose or tight), burn threecovered cigarettes on each different surface location encoun-tered.9.5.1 For the purposes of this test, consider smooth surfaces,welt edges, fused or threaded portions of quilts, and tuftdepressions as different surface locations on a seat cushion.Arrange test cigarettes so that the butt ends burn out on thethreads of a quilt or in tuft depressions.
