21、on upholstered furniture.4. Summary of Test Method4.1 These test methods consist of several tests used toevaluate the cigarette ignition resistance of component mate-rials used in the manufacture of upholstered furniture. Each testinvolves a miniature assembly consisting of the component tobe tested
22、 along with other specified materials, mounted on aplywood mock-up that resembles a small chair seat and back.The assembly is exposed to a lighted cigarette as an ignitionsource.5. Significance and Use5.1 These test methods are intended to estimate the perfor-mance of upholstered furniture under con
23、ditions of exposure toa smoldering cigarette. This is accomplished by testing furni-ture component assemblies. However, interactions betweencomponents in production furniture are not necessarily pre-dicted by component assembly testing.5.2 These test methods are not intended to measure theperformanc
24、e of upholstered furniture under conditions of openflame exposure and do not indicate whether the furniture willresist the propagation of flame under severe fire exposure orwhen tested in a manner that differs substantially from the teststandard.5.3 The results obtained with a material component tes
25、ted inmock-up, in accordance with these test methods, do notnecessarily indicate the performance of the same materialcomponent in other geometric configurations, such as infull-size furniture.6. Apparatus and Materials6.1 Mini-Mock-Up Tester (MMT) (see Fig. 1):6.1.1 The mini-mock-up tester consists
26、of a base with acentrally located guide and a stationary vertical panel, amovable horizontal carriage, and a removable vertical supportpanel.6.1.2 The base consists of two wooden panels, each nomi-nally 8 by 8 in. with nominal 0.75-in. thickness, joined togetherat one edge. The carriage hasa5by8-in.
27、 (125 by 203-mm)platform to support a horizontal specimen. The platform is 2.5in. (38 mm) above the floor of the base and has a 1.5-in.(38-mm) lip at the front edge. The carriage is grooved to fitover a guide provided on the floor of the base. The removablevertical support panel consists of a wooden
28、 panel nominally 8by 8 in. and with nominal 0.75-in. thickness, which standsagainst the vertical wall of the base.6.2 Decking Materials Tester (DMT) (see Fig. 2)Thedecking materials tester consists of a plywood base and aplywood retainer ring. The base measures 21 by 13.5 by 0.5 in.(533 by 343 by 13
29、 mm). The retainer ring measures 21 by 13.5by 0.5 in. with an opening measuring 16 by 8.5 in. (406 by 216mm).6.3 Ignition Source, consisting of cigarettes without filtertips, made from natural tobacco, 3.4 6 0.1 in. (85 6 2 mm)long with a packing density of 0.156 6 0.012 oz/in.2(0.270 6 0.020 g/cm2)
30、 and a total weight of 0.039 6 0.004 oz(1.1 6 0.1 g). The smoldering rate of this cigarette shall be0.236 6 0.024 in./min (0.10 6 0.01 mm/s) when the cigaretteis allowed to burn downward in a draft-protected area.FIG. 1 Mini-Mock-Up TesterFIG. 2 Decking Materials TesterE 1353 08a2NOTE 1With the ciga
31、rette supported at the bottom in a verticalposition, the burning rate is determined in the region from 0.39 to 1.97 in.(10 to 50 mm) measured from the top.6.4 Standard Type I Cover FabricThe standard Type Icover fabric shall be 100 % cotton mattress ticking conformingto Fed. Spec. CCC-C-436-D. It sh
32、all be laundered and tumble-dried once before using.6.5 Standard Type II Cover FabricThe standard Type IIcover fabric shall be UFAC standard Type II, 100 % brightregular rayon, scoured, 20/2, ring spun, basketweave construc-tion, 8.0 6 0.5 oz/yd2(271 6 12 g/m2), undyed, containing noflame-retardant
33、finishes or back coating.6.6 Sheeting MaterialThe sheeting material to cover thetest cigarettes shall be 50 % cotton/50 % polyester or 100 %cotton bed sheeting material weighing 3.7 6 0.8 oz/yd2(125 6 28 g/m2). The material shall be laundered in anautomatic home clothes washing machine and dried in
34、a tumbledrier at least once before use. For testing, the sheeting materialshall be cut into pieces approximately 5 by 5 in. (12.5 by 12.5cm).6.7 Standard Polyurethane Foam SubstrateThe standardpolyurethane foam substrate shall be open-celled polyether-type urethane, containing no inorganic fillers o
35、r flame retar-dants, having a density of 1.3 to 1.6 lb/ft3(20 to 25 kg/m3).6.8 MiscellaneousOther apparatus required to carry outthe testing are: straight pins, a staple gun, a knife or scissors,tongs, and a linear scale graduated in millimeters and tenths ofan inch.6.9 Air VelocityAir velocity acro
36、ss the test assembliesshall be maintained below 50 ft/min (15.2 m/min) in order tominimize localized effects from draft superheating of cigaretteembers.NOTE 2A fume hood with air curtains across the face and zero airvelocity at the test locations is recommended. Zero air velocity isindicated by an u
37、ndisturbed vertical smoke plume of 6 in.6.10 Extinguishing Equipment:6.10.1 Pressurized Water Fire Extinguisher, or other suit-able fire extinguishing equipment, immediately available.6.10.2 Water Bottle, fitted with a spray nozzle to extinguishany ignited portions of the test specimen.6.10.3 Bucket
38、 of Water, for immersing smoldering or burn-ing materials removed from the tester.6.10.4 Tongs, to handle smoldering materials prior to im-mersion.6.10.5 Gloves.6.10.6 Breathing apparatus.6.11 Draft-Free EnclosureAn open draft preventive en-closure shall be provided and used to restrict airflow toco
39、nvection only (see Fig. 3).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 hasdefinitely occurred. Immediately wet
40、 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 avoid exposure to smokeand gases pro
41、duced 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. Conditioning8.1 Condition all test upholstery fabrics and test materials(including polyurethane, cigarettes, and sheeting material) at a
42、temperature of 70 6 5F (21 6 2.8C) and less than 65 %relative humidity for at least 24 h prior to testing. If the testroom conditions do not meet the specifications above for theconditioning room, then the testing shall be initiated within 10min after the specimens are removed from the conditioningr

(0.2 cm),9.1.4.1 Measurements exceeding 2 in. (
44、5.1 cm) shall bereported as follows: 2 in.,9.1.5 Whether Class A or Class B, and9.1.6 Test room conditions.10. Precision and Bias10.1 PrecisionThe precision for measuring cigarette igni-tion resistance classification has not been determined. Resultsof a planned interlaboratory test series will be in
45、cluded whenavailable.10.2 BiasThe true value of cigarette ignition resistanceclassification of upholstered furniture components can only bedefined in terms of a test method. Within this limitation, thesetest methods have no known bias and are generally accepted asreferee methods.COVER FABRIC TEST11.
46、 Test Specimen11.1 Cut three specimens, each 8 by 8 in. (203 by 203 mm),from the material to be tested for horizontal panels, and threespecimens, 8 by 15 in. (203 by 381 mm), for vertical panels.FIG. 3 Draft EnclosureE 1353 08a311.2 Cut each specimen with its long dimension in thedirection of the wa
47、rp and assembled for testing in a warp-to-warp orientation, such that the major areas of weave variationwill lie in the crevice of the assembled test apparatus.11.3 For fabrics with complex weaves, cut specimens sothat portions of the three largest areas of weave complexity arecontacted by the cigar
48、ettes placed on the test assemblies. Fordyed or printed fabrics, or both, color shall not constitute adifference with respect to cigarette ignition resistance in thistest.12. Procedure12.1 For horizontal panels, place the 8 by 8-in. (203 by203-mm) cover fabric specimen on an 8 by 5 by 2-in. (203 by1
