This part of EN 1366 specifies a method for determiningThe fire resistance of vertical and horizontalventilation ducts under standardized fire conditions.The test examinesThe behaviour of ductsexposed to fire fromThe outside (duct A) and fire insideThe duct (duct B).This standard is used inconjunction with EN1363-1.Annex A provides general guidance and gives background information.This Ewopean Standard is not applicable to: a) ducts whose fire resistance depends onThe fire resistance performance of a ceiling; b) ducts containing fire dampers at points whereThey pass through fire separations; c) doors of inspection openings, unless included inThe duct to be tested; d) two or three sided ducts; e) fixing of suspension devices to floors or walls.For evaluation of fire dampers see EN 1366-2.For evaluation of smoke extraction ducts see prEN 1366-8.For evaluation of service ducts and shafts see prEN 1366-5.
