DIN EN 1366-1:2014-12EN 1366-1:2014 (E) 4 Introduction The purpose of this test is to measure the ability of a representative ventilation duct assembly / system that is part of an air distribution system to r
22、esist the spread of fire from one fire compartment to another with fire attack from inside or outside the duct. It is applicable to vertical and horizontal ducts, with or without branches, taking into account joints and openings, as well as suspension devices and penetration points. The test measure
23、s the length of time for which ducts, of specified dimensions, suspended as they would be in practice, satisfy defined criteria when exposed to fire from (separately) both inside and outside the duct. The closed end of each horizontal duct at the back of the furnace is fully restraint. Outside the f
24、urnace, ducts exposed to fire from the outside are tested unrestrained, while ducts exposed to fire from the inside (horizontal only) are tested restrained. The force measurement at horizontal duct B is not mandatory but can be done on the request of the sponsor. The test takes into account the effe
25、ct of fire exposure from the outside where a pressure differential is maintained in the duct as well as the effect of fire entering the ducts in conditions where forced air movement may or may not be present. Caution The attention of all persons concerned with managing and carrying out this fire res
26、istance test is drawn to the fact that fire testing may be hazardous and that there is a possibility that toxic and/or harmful smoke and gases may be evolved during the test. Mechanical and operational hazards may also arise during the construction of the test elements or structures, their testing a
27、nd disposal of test residues. An assessment of all potential hazards and risks to health should be made and safety precautions should be identified and provided. Written safety instructions should be issued. Appropriate training should be given to relevant personnel. Laboratory personnel should ensu
28、re that they follow written safety instructions at all times. DIN EN 1366-1:2014-12EN 1366-1:2014 (E) 5 1 Scope 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 tes
29、ted 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
30、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 duct
31、s; d) fixing of suspension devices (e.g. anchors) to floors or walls. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
