Summary of Test Method4.1 This test method is used to evaluate the cigarette ignition resistance of upholstered furniture by exposing mock-upupholstered furniture ass

21、emblies to lighted cigarettes as an ignition source.5. Significance and Use5.1 This test method is intended to measure the performance of upholstered furniture material assemblies under conditions ofexposure to smoldering cigarettes. This is accomplished by testing furniture assemblies.5.2 This test

22、 method is recommended for upholstered furniture used in facilities such as hospitals, nursing homes,residential-custodial care and supervisory facilities, or in the public area of facilities such as educational, assembly, or residentialoccupancies.5.3 This test method is not intended to measure the

23、 performance of upholstered furniture material assemblies under conditionsof open-flame exposure, and does not indicate whether the assemblies will resist the propagation of flame under severe fireexposure or when tested in a manner that differs substantially from the test method.5.4 The results obt

24、ained with a material assembly tested in mock-up in accordance with this test method do not necessarilyindicate the performance of the same material assembly in other geometric configurations, such as in production furniture.6. Apparatus and Materials6.1 Mock-upElements of the mock-up test jigs are

25、illustrated in Figs. 1 and 2. Fig. 3 shows the completed mock-upassemblies.FIG. 1 Frame for Upholstered Furniture Mock-Up TestE1352 1626.2 Ignition Source, consisting of The ignition source shall consist of SRM 1196 cigarettes without filter tips, made from naturaltobacco 3.4 6 0.13.3 6 0.1 in. (85

26、6 2(83 6 2 mm) long with a tobacco packing density of 0.156 6 0.012 oz/in.3 (0.270 6 0.020g/cmgcm3) and a total weight of 0.039 6 0.004 oz (1.1 6 0.1 g). The smoldering rate of this cigarette shall be 0.236 6 0.024in./min (0.10 6 0.01 mm/s) when the cigarette is allowed to burn downward in a draft-p

27、rotected area. Standard Reference MaterialSRM 1196 is obtained from the National Institute of Standards and Technology.NOTE 1With the cigarette supported at the bottom in a vertical position, the burning rate is determined in the region from 0.39 to 1.97 in. (10 to 50mm), measured from the top.(b) P

29、 be 50 % cotton/50 % polyester or 100 % cottonbed sheeting material weighing 3.7 6 0.8 oz/yd2 (125 6 28 g/m2). The material shall be laundered in an automatic home clotheswashing machine and dried in a tumble drier at least once before use. For testing, the sheeting material shall be cut into pieces

30、approximately 5 by 5 in. (12.5 by 12.5 cm).6.4 Test Area, equipped with a suitable system for exhausting smoke and noxious gases produced during testing. The test shallbe carried out in a draft protected area. The maximum airflow across the sample face shall be less than 50 ft (15.2 m)/min.6.5 Extin

31、guishing Equipment:6.5.1 Pressurized-Water Fire Extinguisher, or other suitable fire-extinguishing equipment, immediately available.6.5.2 Water Botte, fitted with a spray nozzle to extinguish any ignited portions of the mock-up.6.5.3 Bucket of Water, for immersing smoldering or burning materials rem

32、oved from the mock-up.6.5.4 Tongs, to handle smoldering materials prior to immersion.6.5.5 Gloves.6.5.6 Breathing Apparatus.6.6 MiscellaneousOther apparatus required to carry out the testing are:6.6.1 Straight Pins.6.6.2 Knife or Scissors.6.6.3 Linear Scale, at least 6 in. (15 cm) long and graduated

33、 in inches or millimeters in 110 or 116-in. divisions.7. Hazards7.1 WarningEven under the most carefully observed conditions, smoldering combustion can progress to a point where itcannot be readily extinguished. It is imperative that a test be discontinued as soon as continuing combustion has defini

34、telyoccurred. Immediately wet the exposed area with a water spray from the water bottle, remove the charred or burned material, andimmerse the material in a bucket of water. Ventilate the test area.7.2 Products of combustion can be irritating and dangerous to test personnel. Test personnel must avoi

35、d exposure to smoke andgases produced during testing as much as possible. The use of a large hood with a low air velocity during testing is advisable, asa means to remove products of combustion.8. Test Specimen8.1 Specimen ConditioningCondition test samples, cigarettes, and sheeting material at a te

36、mperature of 73.4 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 room conditions do notmeet the above specifications, then testing shall be initiated within 10 min after the materials are removed from the conditionedroom. The mock-up ass

37、embly shall be constructed in the conditioned area.8.2 GeneralProduce furniture mock-up by arranging upholstery cover material and upholstery materials in the same sequenceas they were used in the production furniture. Construct the various parts of the mock-up as described in 8.2 8.7. In all cases,

38、the arrangement and thickness of upholstery material in the mock-up shall reproduce the construction details of the productionfurniture being evaluated.8.3 Loose Seat CushionsMake seat cushions in the same size and manner and with the same material as production furniture.The cushion thickness shall

39、 be a maximum of 5 in. (13 cm).8.3.1 ExceptionUse cushions sized 25 by 22 in. (68 by 55 cm) if actual cushion dimensions exceed these values.8.4 DecksPrepare decks (if they are part of the furniture item) by attaching to the horizontal panel (Fig. 2(a) of the testapparatus the same materials in the

40、same thickness as used in the actual furniture construction. Stretch decking or upholstery covermaterial over the upholstery materials and securely fasten to the underside of the wood panel.8.5 Tight SeatIf the type of furniture item is constructed with only tight seats, duplicate the seat for test

41、in mock-up. Tightseat cushions shall be 18 6 2 by 22 6 2 in. (45 6 5 by 55 6 5 cm) and made of the same fabric and the same thickness used inproduction furniture. Attach the cushion assembly to the horizontal panel of the test apparatus (see Fig. 2(b) by extending theupholstery cover material around

42、 the panel edges and fastening the cover material to the underside of the wood panel.8.6 Side and Back PanelsFurniture sides and backs shall be mocked-up if, in the type of furniture to be represented by themock-up, they are within 1 in. (2.5 cm) of a seat cushion. Make the mock-ups by upholstering

43、one surface of the vertical test panel(see Fig. 2(b) with the same upholstery material and upholstery cover material used in production furniture. Stretch the upholsterycover material over the upholstery material and fasten to the back side of the framework. Cover all edges of the panels with coverm

44、aterial. If the side and back construction of the furniture item are the same, only one vertical panel need be assembled and tested.8.7 BolstersBolsters resting on the seat cushion or suspended above it tend to confine the heat from the cigarette and oftenpresent a spatial arrangement different from

45、 the crevice. In such cases, prepare a mock-up bolster with dimensions to fit into themock-up arrangement and which presents to the cigarette the same spatial arrangement as in production furniture.E1352 1648.8 Armrests and Tops of BacksTest tops of armrests and back if (1) they present a surface la

46、rge enough and so oriented asto support a cigarette and (2) if the construction differs in any way from the side-panel and back-panel constructions. Make topsof armrests and backs by upholstering a piece of 0.5-in. (1.3-cm) thick plywood, approximately 12 by 20 in. (30 by 50 cm) withthe same materia

47、ls used in the furniture item. The mock-up shall reproduce significant details of the construction of productionfurniture.9. Procedure9.1 Assemble a mock-up test sample by attaching the side or back panels, or both, to the mock-up frame and placing a seatcushion (either loose or tight seat construct

48、ion) against the panels, as shown in Fig. 3(b). Place the assembly on a table or platformin the test area under an exhaust hood or other suitable means for exhausting the products of combustion from testing. Testseparately the decks for loose cushion items, top of armrests, and backs. In some cases,

49、 the test to evaluate upholstered furniturematerial assemblies for cigarette ignition resistance will require two vertical panels, one seat cushion (loose or tight), one bolster,one deck, one top of armrest, and one 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 seatcushion and vertical panels meet, seat cushion surfaces (including welt and smooth, quilted or tufted areas), top of upholstered armrest, tops of upholstered back, and deck.9.3 For crevi
