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 separating 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 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 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 should ensure that they follow written safety instructions at all times. SIST EN 1366-7:2004

1 Scope This part of this European 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 like 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 methods 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 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 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, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

Penetrating components shall be installed as given in 7.5. 6.2 Size The test specimen and all its components shall be full size unless limited by the size of the front opening of the furnace which will generally be 3 m × 3 m or in case of horizontal test specimen by the top opening of the furnace. Test specimens which cannot be tested at full size shall be tested to the maximum size possible consistent with 7.2.3. 6.3 Number The number of test specimens shall be selected as described in EN 1363-1. If testing is carried out from one side only, whether due to the fact that the test specimen, including both floor arrangements on either side in terms of their height, is symmetrical or because it is only required to resist fire from one side, this shall be stated in the test report. Figure 3 and Figure 4 give examples of different arrangements. From side Ι in Figure 3 the different arrangements shall be considered installations at floor position (see 5.2.1.1) provided h1 ≤ 500 mm. For h1 > 500 mm this arrangement shall be considered a raised installation (see 5.2.1.2). Any arrangement from side ΙΙ in Figure 3 shall be considered as a raised installation (see 5.2.1.2) provided h2 > 500 mm. Any arrangement in Figure 4 shall be considered from either side as a raised installation (see 5.2.1.2) provided h > 500 mm. For h ≤ 500 mm they shall be considered installations at floor position (see 5.2.1.1). SIST EN 1366-7:2004

EN 1366-7:2004 (E) 15 6.4 Design 6.4.1 General The design of the test specimen and the choice of supporting construction shall take into account the requirements of clause 13 if the widest field of direct application is to be achieved. The test specimen shall be fully representative of the closure and conveyor system assembly intended for use in practice, including any appropriate surface finishes, fittings and penetrating components which are an essential part of the test specimen and may influence its behaviour in the test. Annex C gives general guidance on the design of closure and conveyor system assemblies and their classification for self closing durability. 6.4.2 Pipe and cable end configuration When pipes (e. g. for supply purposes) other than those for transportation of goods/materials are part of the test specimen, the pipe end configurations shall be capped on the exposed side of the test specimen. Capping of pipes shall be carried out by closing the exposed pipe end with a mineral wool disc of a thickness of (75 ± 10) mm and a density of (150 ± 50) kg/m3 fixed in place with an appropriate adhesive (e.g. sodium silicate adhesive). Alternatively, the pipe may be capped by welding a disc of the same material as the pipe onto the end of the pipe together with the mineral wool above. In cases of a vertical test specimen any mineral wool shall be fixed additionally by mechanical means. The heated ends of solid elements such as electrical conductors shall be left uncapped. Cables projecting from the unheated face of the test specimen shall be capped using a proprietary method to prevent hot gases escaping. 6.4.3 Subsequent addition of penetrating components within the penetration seal of a test specimen If it is the intention of the test to represent the effect of adding extra penetrating components or altering the number and/or type of penetrating components running through the penetration seal subsequent to installation in practice at a later servicing life, then the following procedure shall be followed. After installation of the penetration sealing system together with the initial penetrating components into the appropriate supporting construction, the test construction shall be conditioned in accordance with clause 8. After this period any required modifications shall be made to the penetrating component(s) as required to be evaluated and the test construction conditioned again in accordance to clause 8 before testing. Any such procedures shall be fully described in the test report. NOTE This applies particularly for part configuration test specimens as described in 7.6. 6.4.4 Conveyor tracks as pipes or ducts for transportation of airborne particles Conveyor tracks such as pipes or ducts for the transportation of suspended particles together with their closures shall be designed and installed as in practice (see 7.7 for different configurations). 6.5 Construction The test specimen shall be constructed as described in EN 1363-1. 6.6 Verification The sponsor shall provide a specification to a level of detail sufficient to allow the laboratory to conduct a detailed examination of the test specimen before the test and to agree the accuracy of the information supplied. EN 1363-1 provides detailed guidance on verification of the test specimen. SIST EN 1366-7:2004
EN 1366-7:2004 (E) 16 When the method of construction precludes a detailed survey of the specimen, without having to permanently damage it or if it is considered that it will subsequently be impossible to evaluate construction details from a post test examination, then one of two options shall be exercised by the laboratory, either: a) the laboratory shall request to oversee the manufacture of the closure or any other parts of the assembly which are to be the subject of the test; or b) the sponsor shall, at the discretion of the laboratory, be requested to supply, over and above the number of test specimens, an additional assembly or that part of the assembly for which details cannot be verified from the test specimen. The laboratory shall then choose which specimen shall be submitted to the test and which shall be used to verify the construction. 7 Installation of test specimen 7.1 General The test specimen shall be installed, as far as practicable, in a manner representative of its use in practice. Figure 5 to Figure 7 show different installation conditions for vertical and horizontal separating elements in a schematic arrangement. Although the Figures 5 to 7 are shown with horizontal and vertical supporting constructions and test specimens, it is possible for conveyor systems to pass through either non-horizontal or non-vertical supporting constructions or at an angle other than an angle of 90
in two different directions to the supporting construction. NOTE 1 For clarity, penetrations and penetrating components (including conveyor systems) are not shown except for Figure 6 where penetrations are shown. SIST EN 1366-7:2004

EN 1366-7:2004 (E) 20 The test specimen shall be mounted in a supporting construction which covers the type in which it is intended to be used. The design of the connection between the closure and conveyor system assembly and the supporting construction, including any fixings and materials used to make the junction, shall be as used in practice and shall be regarded as part of the test specimen. The closure and frame/guide assembly shall be mounted within or on the supporting construction as done in practice. NOTE 2 There is no need to install e.g. a guide for a closure for a conveyor system which is used to open and shut the closure which otherwise would extend considerably over the test construction limiting therefore the size of the test specimen. The whole area of the test specimen, together with at least the minimum dimensions of the supporting construction required by 7.2.3, shall be exposed to the heating conditions. 7.2 Supporting construction 7.2.1 General The fire resistance of any supporting construction, either floor or wall, shall be at least commensurate with that anticipated for the closure for a conveyor system. The supporting construction chosen for the test may be a standard supporting construction or the actual construction to be used in practice referred to as associated supporting construction. If one of the standard supporting constructions given in 7.2.2 is used, the results may be applicable to a wider field of direct application in accordance with the provisions in clause 13. In accordance with clause 13 the result of a test in an associated supporting construction shall only be applicable to that form of construction. 7.2.2 Standard supporting constructions 7.2.2.1 General The choice of a standard supporting construction shall reflect the intended normal use of the closure and conveyor system assembly. Care shall be taken in selecting a sufficiently rigid standard supporting construction in particular for test specimens intended to represent products to be installed at a height h greater 0,5 m above floor level (raised position) and for any horizontal installation.
