标准范围

ISO 6944-1:2008规定了在标准火灾条件下测定垂直和水平通风管道耐火性的方法。该试验检查了暴露于外部火灾（管道A）和管道内部火灾（管道B）的管道的性能。计划将ISO 6944-1:2008与ISO 834-1结合使用。ISO 6944-1:2008不适用于耐火性取决于天花板耐火性能的管道、穿过防火隔墙处装有防火阀的管道、检查口门（除非包含在待测试管道中）、双面或三面管道，或将悬挂装置固定在地板或墙壁上。提供一般指导和背景信息。

ISO 6944-1:2008 specifies a method for determining the fire resistance of vertical and horizontal ventilation ducts under standardized fire conditions. The test examines the behaviour of ducts exposed to fire from the outside (duct A) and fire inside the duct (duct B). It is intended that ISO 6944-1:2008 be used in conjunction with ISO 834-1.ISO 6944-1:2008 is not applicable to ducts whose fire resistance depends on the fire resistance performance of a ceiling, ducts containing fire dampers at points where they pass through fire separations, doors of inspection openings, unless included in the duct to be tested, two- or three-sided ducts, or the fixing of suspension devices to floors or walls.General guidance and background information are provided.
