DIN EN 1366-1:2014-12

This European Standard specifies a method for determining the fire resistance of vertical and horizontal ventilation ducts including those access panels, which are integral part of the tested ducts. The test examines the behaviour of ducts exposed to fire from the outside (duct A) and fire inside the duct (duct B). This European Standard is used in conjunction with EN 1363-1. Annex A provides general guidance and gives background information. This European Standard is not applicable to: a) ducts whose fire resistance depends on the fire resistance performance of a ceiling or wall (where ducts are located in cavities enclosed by fire-resistant shafts or ceilings); b) ducts containing fire dampers at points where they pass through fire separations; c) one, two or three sided ducts; d) fixing of suspension devices (e.g. anchors) to floors or walls. This European Standard has been prepared by Technical Committee CEN/TC 127 "Fire safety in buildings", the secretariat of which is held by BSI (United Kingdom). The committee responsible for this standard at DIN is NA 005-52-06 AA "Brandverhalten von Baustoff und Bauteilen - Lüftungsleitungen (SpA zu Teilbereichen von CEN/TC 127/WG 2, CEN/TC 127/WG 7, CEN/TC 156/WG 9 und ISO/TC 92/SC 2)" ("Reaction to fire of building materials and building components - Ventilation ducts (national mirror committee for sub-sections of CEN/TC 127/WG 2, CEN/TC 127/WG 7, CEN/TC 156/WG 9 and ISO/TC 92/SC 2)").
