37、g Kong, 21/10/2008 08:04, Uncontrolled Copy, (c) BSI prEN 1366-1:2008 (E) 5 Introduction The purpose of this test is to measure the ability of a representative duct section or duct assembly that is part of an air distribution system to resist the spread of fire from one fire compartment to another w
38、ith 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 exhaust openings, as well as suspension devices and penetration points. The test measures the length of time for which ducts, of specified dime
39、nsions, suspended as they would be in practice, satisfy defined criteria when exposed to fire from (separately) both inside and outside the duct. All ducts are fully restrained in all directions where they are inside the furnace. Outside the furnace, ducts exposed to fire from the outside are tested
40、 unrestrained, while ducts exposed to fire from the inside (horizontal only) are tested restrained. The test takes into account the effect of fire exposure from the outside where a 300 Pa under pressure is maintained in the duct as well as the effect of fire entering the ducts in conditions where fo
41、rced air movement may or may not be present by maintaining a velocity of 3m/s. Ducts exposed to fire from the inside are supplied with air in a manner, which is indicative of the “fan off“, and “fan on“ situations, which could arise in practice. Caution The attention of all persons concerned with ma
42、naging and carrying out this fire resistance 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 el
43、ements or structures, their testing and disposal of test residues. An assessment of all potential hazards and risks to health shall be made and safety precautions shall be identified and provided. Written safety instructions shall be issued. Appropriate training shall be given to relevant personnel.
44、 Laboratory personnel shall ensure that they follow written safety instructions at all times.

45、esistance of vertical and horizontal ventilation ducts including those access panels, which are integral part of the tested ducts/duct walls. The test examines the behaviour of ducts exposed to fire from the outside (duct A) and fire inside the duct (duct B). This Standard is used in conjunction wit
46、h 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; b) ducts containing fire dampers at points where they pass through fire separations; c
47、) access panels, which are evaluated independent from the tested ducts/duct walls; 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 EN 1366-8. For evaluation of service ducts an
48、d shafts see prEN 1366-5. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subseque
