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. Ea
20、ch testinvolves a miniature assembly consisting of the component tobe tested 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
21、are intended to estimate the perfor-mance of upholstered furniture under conditions 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 assem
22、bly testing.5.2 These test methods are not intended to measure theperformance 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
23、from the teststandard.5.3 The results obtained with a material component tested 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 Mi
24、ni-Mock-Up Tester (MMT) (see Fig. 1):6.1.1 The mini-mock-up tester consists 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 nomin
25、al 0.75-in. thickness, joined togetherat one edge. The carriage hasa5by8-in. (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
26、 floor of the base. The removablevertical support panel consists of a wooden 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 aply
27、wood retainer ring. The base measures 21 by 13.5 by 0.5 in.(533 by 343 by 13 mm). The retainer ring measures 21 by 13.5by 0.5 in. with an opening measuring 16 by 8.5 in.

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.NOTE 1With
29、the cigarette 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.FIG. 1 Mini-Mock-Up TesterFIG. 2 Decking Materials TesterE 1353 0226.4 Standard Type I Cover FabricThe standard Type Icover fabric shall

The material s
32、hall 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. (12.5 by 12.5cm).6.7 Standard Polyurethane Foam SubstrateThe standardpolyurethane foam substrate shal
33、l be open-celled polyether-type urethane, containing no inorganic fillers or 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 grad
34、uated in millimeters and tenths ofan inch.6.9 Air VelocityAir velocity across 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
35、at the test locations is recommended. Zero air velocity isindicated by an undisturbed 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
36、nozzle to extinguishany ignited portions of the test specimen.6.10.3 Bucket 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 draf
37、t preventive en-closure shall be provided and used to restrict airflow toconvection 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 discontinu
38、ed 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.7.2 Products of combustion can be irritating and dangerous
39、to test personnel. Test personnel must avoid 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. Conditioning8.1 Condition all test upholstery fabrics and test materials(incl
40、uding polyurethane, cigarettes, and sheeting material) at atemperature 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 1
41、0min after the specimens are removed from the conditioningroom.9.

Precision and Bias10.1 PrecisionThe precision for measuring cigarette igni-tion resistance classification has not been determined.
43、 Resultsof a planned interlaboratory test series will be included whenavailable.10.2 BiasThe true value of cigarette ignition resistanceclassification of upholstered furniture components can only bedefined in terms of a test method.

(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.11.2 Cut each specimen with its long dimension
45、 in thedirection of the warp 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.FIG. 3 Draft EnclosureE 1353 02311.3 For fabrics with complex weaves, cut specimens sothat portions of the three l
46、argest areas of weave complexity arecontacted by the cigarettes 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 by20
