21、ent has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. EN 1366, Fire resistance tests for service installations consists of the following parts: Part 1: Ventilation ducts; Part 2: Fire dampers (the present document); Part 3: Penetration

This standard underwent a formal review process during 2009-2011. Various comments were considered and these were only considered when they added clarity

24、to the procedure. No changes have been made that make historical data redundant. This was deliberately avoided where it was thought to be occurring. If there are some issues with this, consideration should be given to the spirit of the original test combined with the better clarity now given. The fo

25、llowing technical changes were made in this new edition: Changes include the fact that symmetry as a concept has been removed. This does not negate original tests, but may now mean that some additional tests are needed. The figures have been clarified to show some more detail. Testing away from a wa

26、ll or floor now has an equal distance between damper and the supporting construction. In this instance, historical data is not negated but any testing done after the publication of this standard needs to be done to the new dimensions. BS EN 1366-2:2015EN 1366-2:2015 (E) 5 Further information is give

BS EN 1366-2:2015EN 1366-2:2015 (E) 6 Introduction The purpose of the test is to evaluate the ability of a fire damper to prevent fire and smoke spreading from one fire compartment to another through the air ductwork

31、 system which may penetrate fire separating walls and floors. The fire damper is attached (directly or remotely via a section of ducting), to a fire separating element in a manner representative of practice. Tests are performed starting with the fire damper in the open position to expose the tempera

32、ture sensing element of the fire damper to furnace conditions. Temperature and integrity measurements are carried out in various parts of the test construction during the test. The leakage of the fire damper system is measured (continuously during the test) by direct flow measurements whilst maintai

33、ning a constant pressure differential across the closed fire damper of 300 Pa. The leakage of the fire damper in the closed position is also measured at ambient temperature, when a reduced leakage classification needs to be achieved. An additional test to prove insulation characteristics may be need

34、ed if the damper needs to be used un-ducted on one side or on both sides. This test is not needed where such evidence is not required, or if insulation is not a requirement of performance, in the specific application. Caution The attention of all persons concerned with managing and carrying out this

35、 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 elements or structures, their

36、testing and 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 sh

37、ould ensure that they follow written safety instructions at all times. BS EN 1366-2:2015EN 1366-2:2015 (E) 7 1 Scope This European Standard specifies a method for determining the fire resistance of fire dampers installed in fire separating elements designed to withstand heat and the passage of fire,

38、 smoke and gases at high temperature. This European Standard is used in conjunction with EN 1363-1. This standard is not suitable for testing fire dampers in suspended ceilings. This standard is not suitable for testing non-mechanical fire dampers (see EN 1366-12). 2 Normative references The followi
