2022-06-11 08:34:00 【中科易朔】
UL 2043 标准名称:
UL 2043: Fire test for heat and visible smoke release for discrete products and their accessories installed in air-handling spaces
UL 2043: 空气处理场所使用的个别分离性产品及其附件热和可见烟雾释放的防火测试
UL 2043 测试概括:
这是一种火灾试验方法,用于确定拟安装在空气处理空间(如吊顶上方)的离散产品(电气设备)的火灾性能响应。将这些产品置于明火点火源下,并使用产品热量计进行评估。
本试验的目的是根据国家电气规范NFPA 70的规定,确定燃烧产品样品的热释放率和烟雾释放率,因为它们与耐火和低烟产生特性的要求有关。
本试验方法不提供产品在其他火灾或试验条件下的性能信息。本试验不调查燃烧产物的毒性。
本试验不包括产品的结构、电气或其他性能要求
UL 2043 标准判定依据:
a)每次试验中测得的峰值放热速率(hrr)应小于或100千瓦。
b)每次试验测得的烟气峰值释放速率不超过0.21m2/s, SRRS。
c)总排烟量(10分钟测试时间)不超过75m2, TSR。
样品:
实际样品1个
建材其他标准:
EN 13501-1: 建筑制品和构件的火灾分级第一部分:用对火反应试验数据的分级
DIN 4102-1: 建筑材料和构件的防火性能第一部分:建筑材料要求和测试的分类等级
NF P 92-501: 法国材料阻燃防火测试M等级测定-刚性材料
NF P 92-503: 法国材料阻燃防火测试M等级测定-柔性材料
BS 476-6:建筑材料和构件的防火测试.第6部分:制品火势蔓延的测试方法
BS 476-7:建筑材料和构件的防火测试.第7部分:测定产品火焰表面蔓延分类的测试方法
