UL 10B Fire Test of Door Assemblies
UL 10B 针对门系统结构的防火测试
UL防火认证-UL10B-防火门防火测试认证 – UL认证简述
UL认证是为市场得到具有相当安全水准的商品，为人身健康和财产安全得到保证作出贡献。就产品安全认证作为消除国际贸易技术壁垒的有效手段而言，UL为促进国际贸易的发展也发挥着积极的作用。
UL防火认证-UL10B-防火门防火测试认证－涵盖范围：
– These methods of fire tests are applicable to door assemblies of various materials and types of construction for use in wall openings to retard the passage of fire
– Tests made in conformity with these test methods register performance during the test exposure; and such tests shall not be construed as determining compliance for use after exposure to fire
– It is the intent that tests made in conformity with these test methods develop data to enable regulatory bodies to determine the compliance of door assemblies for use in locations where fire resistance of a specified duration is required.
– These methods are intended to evaluate the ability of a door assembly to remain in an opening during a predetermined test exposure
– The tests expose a specimen to a standard fire exposure controlled to achieve specified temperatures throughout a specified time period, followed by the application of a specified standard fire hose stream. The exposure, however, is not representative of all fire conditions, which vary with changes in the amount, nature, and distribution of fire loading, ventilation, compartment size and configuration, and heat sink characteristics of the compartment. It does, however, provide a relative measure of fire performance of door assemblies under these specified fire exposure conditions.
