30、OT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULINTRODUCTION1 Scope1.1 The purpose of this test method is to determine the ability of foamed plastics and products containingfoamed plastics used for decorative purposes to resist rapid heat release when subjected to a f
31、lamingignition source.1.2 This test method is intended to apply to foamed plastics, and products containing foamed plastics, tobe used for the following decorative purposes:a) Typical open-ceiling, portable exhibit booth constructions incorporating manufactured panels.b) Individual, manufactured dec
32、orative objects such as, but not limited to, mannequins, murals,and signs.c) Theater, motion picture, and television stage settings, with or without horizontal projections.1.3 This test method does not provide information concerning the fire performance of foamed plastics inother fire conditions or
33、the contribution of foamed plastics to a developing fire condition. Also, the densityof smoke produced and the toxicity of the products of combustion are not measured.1.4 Appropriate identifications and examinations shall be conducted to provide additional informationrelative to the physical and che
34、mical properties of the foamed plastics used.1.5 A product that contains features, characteristics, components, materials, or systems new or differentfrom those covered by the requirements in this standard, and that involve a risk of fire, electric shock, orinjury to persons shall be evaluated using
35、 the appropriate additional component and end-productrequirements as determined necessary to maintain the acceptable level of safety as originally anticipatedby the intent of this standard. A product whose features, characteristics, components, materials, orsystems conflict with specific requirement
36、s or provisions of this standard cannot be judged to comply withthis standard. Where considered appropriate, revision of requirements shall be proposed and adopted inconformance with the methods employed for development, revision, and implementation of this standard.2 General2.1 When a value for mea
37、surement is followed by a value in other units in parentheses, the first statedvalue is the requirement.2.2 The term foamed plastics used in these requirements includes materials containing foamed plastics.NOVEMBER 27, 2006UL 19754UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDIS

40、components:a) A wood crib ignition source;b) A collection hood and exhaust duct;c) Velocity and temperature measuring instruments;d) Gas sampling and oxygen analysis equipment;e) A data acquisition system; andf) Photographic and video equipment.4.1.2 The building in which the tests are conducted is
41、to have vents for the discharge of the combustionproducts and have provisions for fresh air intake so that no oxygen-deficient air is introduced into the testconfiguration during the test.NOVEMBER 27, 2006 UL 1975 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOU
42、T PERMISSION FROM UL4.2 Wood crib ignition source4.2.1 The ignition source for the test is to consist of a 340 15 g (0.75 0.03 lb) wood crib and 20 1g(0.04 0.002 lb) of wood excelsior placed in the interior cavity of the crib. The wood crib is to consist ofthe following:a) 12.7 by 12.7 by 76.2 mm (1
43、/2 by 1/2 by 3 inch) long sticks of Yellow Poplar species lumber.Forty sticks are to form the bottom section and twenty are to form the top section.b) Wood adhesive capable of being used for purposes of assembling the crib.The wood excelsior is to consist of finely shredded SPF grade lumber.4.2.2 Th
44、e crib is to be assembled as shown in Figure 4.1. Two sticks are to be used in each row. Thesticks in each row are to be parallel to one another and at right angles to the sticks in the adjacent row.The sticks are to be glued together at points of contact with adhesive. The top crib section is to re
45、st onthe center of the bottom crib section. No glue is to be used to secure the two sections together.This is generated text for figtxt.4.2.3 The wood crib and excelsior are to be conditioned at 49 5.5C (120 10F) and 20 5 percentrelative humidity until constant weight is achieved.Figure 4.1Wood crib

The face dimensions of the hood areto be at least 2.4 by
47、2.4 m (8 by 8 feet) and the depth is to be at least 1.07 m (3.5 feet). The hood is toexhaust into a plenum having a 0.9 by 0.9 m (3 by 3 foot) cross section. The distance between the loweredge of the hood and the floor is to be 1.83m(610feet). The system is shown in Figure 4.2.This is generated text
48、 for figtxt.4.3.2 The exhaust duct is to be connected to the plenum. The duct is to run horizontally in length (10diameters) downstream from the last turn or restriction prior to the location of instrumentation to providefor a fully developed gas flow. Mixing vanes are to be provided in the duct whe
49、n concentration gradientsare determined to exist. The outlet of the exhaust duct is to be connected to an exhaust plenum containingsmoke abatement equipment.4.3.3 The exhaust system is to have sufficient draft to collect all products of combustion developed by theburning sample. The exhaust flow is to be variable from 0.47 2.35 m3/s (1000 5000 cubic feet perminute).4.3.4 An alternative hood and exhaust system design is capable of being used when it has been shownto produce equivalent
