适用范围：This part of ISO 6944 specifies a method for determining the fire resistance of vertical and horizontalventilation ducts under standardized fire conditions. The test examines the behaviour of ducts exposed to firefrom the outside (duct A) and fire inside the duct (duct B). It is intended that this part of ISO 6944 be used inconjunction with ISO 834-1.This part of ISO 6944 is not applicable toa) ducts whose fire resistance depends on the fire resistance performance of a ceiling,b) ducts containing fire dampers at points where they pass through fire separations,c) doors of inspection openings, unless included in the duct to be tested,d) two- or three-sided ducts,e) the fixing of suspension devices to floors or walls.
