Summary of Test Method4.1 These test methods consist of several tests used to evaluate the cigarette ignition resistance of component materials used inthe manufacture of upholstered furniture. Each test involves a miniature assembly consist
24、ing of the component to be tested, alongwith other specified materials, mounted on a plywood mock-up that resembles a small chair seat and back.The assembly is exposedto a lighted cigarette as an ignition source.5. Significance and Use5.1 These test methods are intended to estimate the performance o
25、f upholstered furniture under conditions of exposure to asmoldering cigarette. This is accomplished by testing furniture component assemblies. However, interactions between componentsin production furniture are not necessarily predicted by component assembly testing.5.2 These test methods are not in
26、tended to measure the performance of upholstered furniture under conditions of open flameexposure, and do not indicate whether the furniture will resist the propagation of flame under severe fire exposure or when testedin a manner that differs substantially from the test standard.5.3 The results obt
27、ained with a material component tested in mock-up, in accordance with these test methods, do not necessarilyindicate the performance of the same material component in other geometric configurations, such as in full-size furniture.6. Apparatus and Materials6.1 Mini-Mock-Up Tester (MMT) (see Fig. 1):6
28、.1.1 The mini-mock-up tester consists of a base with a centrally located guide and a stationary vertical panel, a movablehorizontal carriage, and a removable vertical support panel.6.1.2 The base consists of two wooden panels, each nominally 8 by 8 in. with nominal 0.75-in. thickness, joined togethe

39、esterFIG. 2 Decking Materials TesterE1353 1636.9 Air VelocityAir velocity across the test assemblies shall be maintained below 50 ft/min (15.2 m/min) in order to minimizelocalized effects from draft superheating of cigarette embers.NOTE 1A fume hood with air curtains across the face and zero air vel
40、ocity at the test locations is recommended. Zero air velocity is indicated byan undisturbed vertical smoke plume of 6 in.6.10 Extinguishing Equipment:6.10.1 Pressurized Water Fire Extinguisher, or other suitable fire extinguishing equipment, immediately available.6.10.2 Water Bottle, fitted with a s
41、pray nozzle to extinguish any ignited portions of the test specimen.6.10.3 Bucket of Water, for immersing smoldering or burning materials removed from the tester.6.10.4 Tongs, to handle smoldering materials prior to immersion.6.10.5 Gloves.6.10.6 Breathing apparatus.6.11 Draft-Free EnclosureAn open
42、draft preventive enclosure shall be provided and used to restrict airflow to convection only(see Fig. 3).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 disco
43、ntinued as soon as continuing combustion has definitelyoccurred. 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 da
44、ngerous to test personnel. Test personnel must avoid 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. Conditioning8.1 Condition all test upholstery fabric
45、s and test materials (including 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 test roomconditions do not meet the specifications above for the conditioning room, then the testing
46、 shall be initiated within 10 min afterthe specimens are removed from the conditioning room.9.
