21、om. EN 1366-7:2004 (E) 5 Introduction This part of this European Standard was developed to provide a method of fire resistance testing for assessing the contribution of a closure for a conveyor system together with all its anchoring parts and the frame/guide included to the fire resistance of a sepa

22、rating element when penetrated by a conveyor system including any relevant penetrating components. Caution The attention of all persons concerned with managing 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 toxi

23、c 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 and disposal of test residues. An assessment of all potential hazards and risks to health should be made and sa

24、fety precautions should be identified and provided. Written safety instructions should be issued. Appropriate training should be given to relevant personnel. Laboratory personnel should ensure that they follow written safety instructions at all times. EN 1366-7:2004 (E) 6 1 Scope This part of this E

25、uropean Standard specifies a method of fire testing to determine the fire resistance of closure and conveyor system assemblies designed for installation within openings of separating elements, including any sealing necessary between the closure for a conveyor system and any penetrating components li

26、ke conveyor tracks, electrical cables and pneumatic pipes being essential parts of the closure and conveyor system assembly together with the penetration seal. This part of European Standard is not applicable to other test methods required to fully assess closures for conveyor systems, e.g. test met

27、hods to evaluate the serviceability and reliable functioning of interconnected systems. The fire testing of fire dampers for heating and ventilation systems, fire doors and shutters for normal traffic paths and the movement of liquid and combustible gas, are specifically excluded from this European

28、Standard. This European Standard is read in conjunction with EN 1363-1. In the absence of any European Technical Specification for closure and conveyor system assemblies, this European Standard gives advice on the classification of durability for closure and conveyor system assemblies. 2 Normative r
