    1 Scope

    1.1 The purpose of this test method is to determine the ability of foamed plastics and products containing foamed plastics used for decorative purposes to resist rapid heat release when subjected to a flaming ignition source.

    1.2 This test method is intended to apply to foamed plastics, and products containing foamed plastics, to be used for the following decorative purposes:

    a)    Typical open-ceiling, portable exhibit booth constructions incorporating manufactured panels.

    b)    Individual, manufactured decorative 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 in other fire conditions or the contribution of foamed plastics to a developing fire condition. Also, the density of 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 information relative to the physical and chemical properties of the foamed plastics used.

    1.5 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involve a risk of fire, electric shock, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the acceptable level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard cannot be judged to comply with this standard. Where considered appropriate, revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
