通气建筑用非机械防火挡板的消防试验方法

标准编号: ASTM E2912-2017
标准名称: 通气建筑用非机械防火挡板的消防试验方法
英文名称: Standard Test Method for Fire Test of Non-Mechanical Fire Dampers Used in Vented Construction
实施时间:
范围: 1.1 This fire-test-response standard assesses the ability of non-mechanical fire dampers used in vented construction in its open state to limit passage of hot gases, radiation, and flames during a prescribed fire test exposure. The fire exposure condition in this test method is sudden direct flame impingement, which produces these hot gases, radiation, and flames. Note 1: Non-mechanical fire dampers can be used in vented construction. Vented constructions may be parts of buildings including walls, floors, ceilings and concealed spaces and cavities used for air transfer and to allow ventilation in structures without ductwork. Non-mechanical fire dampers can be located adjacent to combustible construction or materials and situated in exposed or concealed locations, or both. Unlike typical fire resistive assemblies, vented construction uses non-mechanical fire dampers to allow air transfer without the use of ducts. Resistance to flame, radiation, and hot gases may be requirements when direct flame impingement is a credible risk, or when no penetration of flames is required by the authority having jurisdiction, or both. The proposed test method provides procedures that enable an assessment of this direct flame impingement on non-mechanical fire dampers. This test method does not alter any requirements for non-mechanical fire dampers used in fire resistance rated construction and assemblies. 1.2 This fire-test-response standard is intended to provide a means to assess the reaction of a non-mechanical fire damper used in vented construction to sudden direct flame impingement, or as a supplement to existing fire-resistive test methods, or both. 1.3 This test method does not circumvent or eliminate the fire resistance rating requirements for construction. The fire resistance rating of construction shall be tested in accordance with published fire-resistance test standards as appropriate for the relevant application of the construction, or as re
