(Main)Fire resistance tests for non-loadbearing elements - Part 5: Air transfer grilles
Fire resistance tests for non-loadbearing elements - Part 5: Air transfer grilles
This test method specifies a method for determining the fire resistance of air transfer grilles(ATG).
It is applicable to air transfer grilles intended for installation in building components (typically walls, floors or ceilings). The orientation of the installation of the air transfer grille can be vertical or horizontal.
The closing mechanism of the air transfer grille can come from expansion of material and/or from any mechanical or electrical closing device.
This test method is valid for fire resistant or fire resistant and smoke control air transfer grilles.
This test method evaluates the behaviour of the air transfer grille when exposed to the standard fire curve described in EN 1363-1 and the standard pressure described in EN 1363-1.It is not the intention of this test to provide quantitative information on the rate of leakage of smoke and/or hot gases or on the transmission or generation of fumes under fire conditions. Such phenomena are only to be noted in describing the general behaviour of test specimens during the test.
The rate of leakage of smoke at ambient temperature or at 200°C is addressed in product technical specifications (e.g. in ETAG 026 – part 4)
All values given in this standard are nominal unless otherwise specified.
This test method is not valid for determining the fire resistance of air transfer grilles that are used in ducts because ATG are considered as separating elements. The test method for ATG, used in ducts is described in the corresponding duct standards.
Non-mechanical fire barriers for ventilation ductwork according to EN 1366-12 are excluded.
This test method is not valid for determining the fire resistance of air transfer grilles in fire doors, shutters and openable windows as specified in EN 1634-1 and EN 1364-2, because the deformation of fire doors, shutters and openable windows in fire conditions differs from the deformation of flexible/rigid walls. Moreover the location of TC in the door standard is too specific to be handled in this standard.
Feuerwiderstandsprüfungen für nichttragende Bauteile - Teil 5: Lüftungsgitter
Diese Norm legt ein Prüfverfahren zur Bestimmung der Feuerwiderstandsdauer von Lüftungsgittern (LG) fest.
Sie gilt für Lüftungsgitter zum Einbau in Gebäudeteile (typischerweise Wände, Decken oder Unterdecken). Der Einbau der Lüftungsgitter kann vertikal oder horizontal erfolgen.
Der Schließmechanismus der Lüftungsgitter kann auf der Ausdehnung der Baustoffe und/oder auf jeglichen mechanischen oder elektrischen Schließvorrichtungen beruhen.
Das hier beschriebene Prüfverfahren gilt für feuerwiderstandsfähige Lüftungsgitter sowie für Lüftungsgitter mit Feuerwiderstand und Rauchschutzeigenschaften.
Mit dem Prüfverfahren wird das Verhalten des Lüftungsgitters bewertet, wenn dieses der Norm-Brandkurve und dem Normdruck nach EN 1363 1 ausgesetzt ist. Diese Prüfung ist nicht dafür vorgesehen, quantitative Angaben zur Leckrate von Rauch und/oder heißen Gasen oder zur Übertragung oder Erzeugung von Rauch unter Brandbedingungen zu liefern. Derartige Phänomene sind lediglich im Zusammenhang mit der Beschreibung des allgemeinen Verhaltens der Probekörper während der Prüfung aufzuzeichnen.
Die Leckrate von Rauch bei Umgebungstemperatur bzw. bei 200 °C wird in technischen Produkt¬spezifikationen (z. B. ETAG 026 — Teil 4) behandelt.
Sofern nicht anders festgelegt, handelt es sich bei allen Werten nach dieser Norm um Nennwerte.
Das hier beschriebene Prüfverfahren gilt nicht für die Bestimmung des Feuerwiderstands von Lüftungsgittern, die in Kanälen/Schächten eingesetzt werden, da LG als raumabschließende Bauteile betrachtet werden. Das Prüfverfahren für LG zur Anwendung in Kanälen/Schächten wird in den entsprechenden Normen zu den Kanälen/Schächten beschrieben.
Nichtmechanische Brandschutzverschlüsse für Lüftungsleitungen nach EN 1366 12 sind vom Anwendungs-bereich dieser Norm ausgenommen.
Das Prüfverfahren gilt nicht für die Bestimmung des Feuerwiderstands von Lüftungsgittern in Brandschutztüren, Abschlüssen und zu öffnenden Fenstern nach EN 1634 1 bzw. EN 1364 2, da die Verformung von Brandschutztüren, Abschlüssen und zu öffnenden Fenstern unter Brandbedingungen von der Verformung flexibler/starrer Wände abweicht. Darüber hinaus sind die Angaben zur Anordnung der Thermoelemente (TC, en: thermocouple) in der türbezogenen Norm zu spezifisch, um in der vorliegenden Norm behandelt werden zu können.
Essais de résistance au feu des éléments non porteurs - Partie 5: Grilles de transfert
La présente méthode d’essai spécifie une méthode permettant de déterminer la résistance au feu des grilles de transfert.
Elle s’applique aux grilles de transfert destinées à être installées dans des éléments de construction (généralement des murs, des planchers ou des plafonds). L’orientation de l’installation de la grille de transfert peut être verticale ou horizontale.
Le mécanisme de fermeture de la grille de transfert peut être dû à la dilatation du matériau et/ou à un dispositif de fermeture mécanique ou électrique.
La présente méthode d’essai est valable pour les grilles de transfert résistantes au feu ou résistantes au feu et étanches à la fumée.
La présente méthode d’essai évalue le comportement de la grille de transfert lorsqu’elle est exposée à la courbe de feu normalisée décrite dans l’EN 1363-1 et à la pression normale décrite dans l’EN 1363-1. Cet essai n’a pas pour but de fournir des informations quantitatives sur le taux de fuite de la fumée et/ou des gaz chauds, ni sur la transmission ou la génération de fumées en cas d’incendie. Ces phénomènes doivent seulement figurer dans la description du comportement général des éléments d’essai pendant l’essai.
Le taux de fuite de la fumée à la température ambiante ou à 200 °C est traité dans les spécifications techniques de produits (par exemple ETAG 026 – partie 4).
Toutes les valeurs indiquées dans la présente norme sont des valeurs nominales, sauf spécification contraire.
La présente méthode d’essai n’est pas valable pour la détermination de la résistance au feu des grilles de transfert utilisées dans des conduits car ces grilles sont considérées comme des éléments de séparation. La méthode d’essai des grilles de transfert utilisées dans des conduits est décrite dans les normes correspondantes se rapportant aux conduits.
Les barrières résistantes au feu non mécaniques pour les conduits de ventilation conformes à l’EN 1366 12 sont exclues.
La présente méthode d’essai n’est pas valable pour la détermination de la résistance au feu des grilles de transfert dans les portes, fermetures et fenêtres coupe-feu tels que spécifiés dans l’EN 1634-1 et l’EN 1364-2, car la déformation de ces éléments en cas d’incendie est différente de celle des murs flexibles/rigides. En outre, l’emplacement des thermocouples dans la norme relative aux portes est trop spécifique pour être traité dans la présente norme.
Preskusi požarne odpornosti nenosilnih elementov - 5. del: Prezračevalne rešetke
Ta preskusna metoda določa metodo za ugotavljanje požarne odpornosti prezračevalnih rešetk (ATG).
Uporablja se za prezračevalne rešetke, namenjene za namestitev v sestavnih delih zgradb (običajno v stenah, tleh ali stropih). Prezračevalne rešetke je mogoče namestiti navpično ali vodoravno.
Zapiralni mehanizem prezračevalne rešetke lahko vključuje raztezanje materiala in/ali mehansko ali električno zapiralno napravo.
Ta preskusna metoda se uporablja za protipožarne ali dimne prezračevalne rešetke.
Ta preskusna metoda omogoča vrednotenje lastnosti prezračevalne rešetke, izpostavljene standardni požarni krivulji v skladu s standardom EN 1363-1 in standardnemu tlaku v skladu s standardom EN 1363-1. Ta preskus ni predviden za pridobivanje kvantitativnih podatkov o stopnji izpusta dimov in/ali vročih plinov ali prenosu/nastajanju dimov v požarnih razmerah. Te pojave je treba upoštevati le pri opisovanju splošnih lastnosti preskušancev med preskusom.
Stopnja izpusta dimov pri temperaturi okolja 200 °C je opisana v tehničnih specifikacijah proizvodov (npr. v dokumentu ETAG 026 – 4. del).
Vse vrednosti, navedene v tem standardu, so nominalne, razen če ni določeno drugače.
Ta preskusna metoda se ne uporablja za ugotavljanje požarne odpornosti prezračevalnih rešetk, ki se uporabljajo v prezračevalnih kanalih, ker se prezračevalne rešetke obravnavajo kot ločeni elementi. Preskusna metoda za prezračevalne rešetke, ki se uporabljajo v prezračevalnih kanalih, je opisana v ustreznih standardih za kanale.
Nemehanske požarne pregrade za sistem prezračevalnih kanalov v skladu s standardom EN 1366-12 so izključene.
Ta preskusna metoda se ne uporablja za ugotavljanje požarne odpornosti prezračevalnih rešetk v protipožarnih vratih, polknih in oknih, ki se odpirajo, kot so opredeljena v standardih EN 1634-1 in EN 1364-2, saj se deformacija protipožarnih vrat, polken in oken, ki se odpirajo, v požarnih razmerah razlikuje od deformacije upogljivih/togih zidov. Poleg tega je mesto TC v standardu o vratih preveč specifično za obravnavo v tem standardu.

EN 1364-5:2017 (E) 4 European foreword This document (EN 1364-5:2017) has been prepared by Technical Committee CEN/TC 127 “Fire safety in buildings”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2017, and conflicting national standards shall be withdrawn at the latest by December 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. EN 1364 ‘Fire resistance tests for non-loadbearing elements’ consists of the following parts: — Part 1: Walls — Part 2: Ceilings — Part 3: Curtain walling - Full configuration (complete assembly) — Part 4: Curtain walling - Part configuration — Part 5: Air transfer grilles — Part 6: Cavity Barriers According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 1364-5:2017
EN 1364-5:2017 (E) 5 Introduction The purpose of this test is to measure the ability of a representative specimen of an air transfer grille to resist the spread of fire from one side to another. A representative sample of the air transfer grille is exposed to a specified regime of heating and the performance of the test specimen is monitored on the basis of criteria given in this standard. Fire resistance of the test specimen is expressed as the time for which the appropriate criteria have been satisfied. The times so obtained are a measure of the adequacy of the construction in a fire but have no direct relationship with the duration of a real fire. CAUTION - The attention of all persons concerned with managing and carrying out this furnace testing is drawn to the fact that fire testing can be hazardous and that there is a possibility that toxic and/or harmful smoke and gases can be evolved during the test. Mechanical and operational hazards can 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 1364-5:2017
EN 1364-5:2017 (E) 6 1 Scope This European Standard specifies a method for determining the fire resistance of air transfer grilles (ATG). It is applicable to air transfer grilles intended for installation in building components (typically walls, floors or ceilings). The orientation of the installation of the air transfer grille can be vertical or horizontal. The closing mechanism of the air transfer grille can come from expansion of material and/or from any mechanical or electrical closing device. This test method is valid for fire resistant or fire resistant and smoke control air transfer grilles. An additional test configuration is valid for fire resistant or fire resistant and smoke control air transfer grilles in applications where flame impingement is a risk during open state from start of fire (Annex A). This test method evaluates the behaviour of the air transfer grille when exposed to the standard fire curve described in EN 1363-1 and the standard pressure described in EN 1363-1. It is not the intention of this test to provide quantitative information on the rate of leakage of smoke and/or hot gases or on the transmission or generation of fumes under fire conditions. Such phenomena are only to be noted in describing the general behaviour of test specimens during the test. The rate of leakage of smoke at ambient temperature or at 200 °C as an optional requirement for ATG with declared smoke control will be confirmed in accordance with standard EN 1634-3. This test method is not valid for determining the fire resistance of air transfer grilles that are used in ducts because ATG are considered as separating elements. The test method for ATG, used in ducts is described in the corresponding duct standards. This test method is not valid for determining the fire resistance of a fire damper or a fire barrier connected to a duct on either or both sides because an ATG is tested as a fire-separating element on its own. Fire dampers are tested according to EN 1366-2. Non-mechanical fire barriers are tested according to EN 1366-12. This test method is not valid for determining the fire resistance of air transfer grilles in fire doors, shutters and openable windows as specified in EN 1634-1 and EN 1364-2, because the deformation of fire doors, shutters and openable windows in fire conditions differs from the deformation of flexible/rigid walls. Moreover the location of thermocouples in the door standard is too specific to be handled in this standard. All values given in this standard are nominal unless otherwise specified. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1363-1, Fire resistance tests - Part 1: General Requirements EN 1363-2, Fire resistance tests - Part 2: Alternative and additional procedures EN ISO 13943, Fire safety - Vocabulary (ISO 13943) SIST EN 1364-5:2017
EN 1364-5:2017 (E) 7 3 Terms and definitions For the purposes of this document, the definitions given in EN 1363-1, EN 1363-2 and EN ISO 13943, together with the following, apply. 3.1 air transfer grille device consisting of an active/reactive part which could include a decorative cover as to be used in practice, allowing movement of air at ambient temperature and pressure and providing fire resistance in case of fire 3.2 air transfer grille flow zone total visible surface area of the air transfer grille which allows air to flow from one side to the other (this excludes the air transfer grille frame) 3.3 air transfer grille face total surface area of the air transfer grille in its non-installed state (this includes any air transfer grille frame) 3.4 aperture opening in the supporting construction in which the air transfer grille is installed and sealed off towards the supporting construction 3.5 modular air transfer grilles air transfer grilles that can be fitted together to form a larger ATG unit 4 Test equipment See EN 1363-1 and, if applicable, EN 1363-2. 5 Test conditions 5.1 Heating conditions The heating conditions and the furnace atmosphere shall conform to those given in EN 1363-1 or, if applicable, EN 1363-2. 5.2 Pressure conditions Pressure conditions and tolerances shall be as given in EN 1363-1. Depending on the field of application, air transfer grilles installed in vertical supporting constructions can be tested in the positive or negative pressure zone. If the grille is intended for both zones, both scenarios should be tested. If both tests are done in 1 set-up, the pressure level in the furnace will be organized such that the 0-level is situated between the specimens to be tested in a negative and positive pressure zone. The height of the 0-level in the furnace will therefore be adjusted according to the tested specimen. SIST EN 1364-5:2017
EN 1364-5:2017 (E) 8 Air transfer grilles installed in horizontal supporting constructions are always considered as being positioned in the positive pressure zone. For ATG installed in a horizontal separating element, the pressure shall be controlled to (20 ± 3) Pa at 100 mm below the underside of the separating element to which it is fixed. The pressure during the test at the top and at the bottom of the ATG will be calculated and reported in the test report and in the classification report. The corresponding height above notional floor level of top and bottom of the ATG shall also be reported. 6 Test specimen 6.1 General The test specimen consists of an air transfer grille together with a supporting construction. In cases where multiple test specimens are included in a single test construction, they shall be the subject of a separate evaluation. 6.2 Size The test specimen shall be normally full size. If modular air transfer grilles are tested, the largest assembly size shall be tested. In order to avoid boundary effects, the distance between the perimeter of the air transfer grille and the internal surfaces of the furnace shall be not less than 200 mm at any point. In cases where multiple test specimens are included in a single test construction, the minimum distance between adjacent air transfer grilles shall be not less than 200 mm. However, if a specific installation requires smaller distance, then ATG shall be tested to the minimum separation used in practice. 6.3 Number For grilles installed in vertical supporting constructions, the number of test specimens required is given in EN 1363-1. For horizontal separating elements, only one test specimen is required with fire exposure from the underside. For grilles that are not symmetrical, each side has to be tested. Where an air transfer grille is intended for use both in floors and walls, the ATG shall be tested both vertically and horizontally. 6.4 Design 6.4.1 General The test specimen shall be fully representative of the air transfer grille used in practice, including any special features which are unique to the grille, e.g. decorative covers. Each shape (e.g. circular, rectangular) with maximum dimensions has to be tested, to give widest application according to the field of direct application (Clause 13). 6.4.2 Restraint The edges of the test specimen shall be restrained as in practice. The method of restraining the air transfer grille is considered part of the test specimen. SIST EN 1364-5:2017
EN 1364-5:2017 (E) 9 6.5 Construction The test specimen shall be constructed as described in EN 1363-1. 6.6 Verification Verification of the test specimen shall be carried out as described in EN 1363-1. 7 Installation of test specimen 7.1 General The test specimen shall be installed, as far as possible, in a manner representative of the use in practice. Inclusion of decorative covers: Where decorative covers are to be supplied with the air transfer grille and installed symmetrically, testing of the air transfer grille shall also include the decorative covers as part of the test specimen. If the decorative cover will be installed non symmetrically, a test of the decorative cover inside and outside the fire shall be required. 7.2 Supporting constructions 7.2.1 General The standard supporting constructions given in EN 1363-1 apply. The supporting construction chosen for the test may be a non-standard support construction. However, the result is then only applicable to this non-standard support construction. 7.2.2 Walls For air transfer grills intended to be installed in walls, the following supporting constructions described in EN 1363-1 apply: — High density rigid construction; — Low density rigid construction; — Flexible construction; — Non-standard supporting construction. 7.2.3 Floors For air transfer grilles intended to be installed in floors, the following supporting constructions described in EN 1363-1 apply: — High density rigid construction; — Low density rigid construction; — Non-standard supporting construction. NOTE Suspended ceilings described in EN 1364–2, are non-standard supporting constructions. SIST EN 1364-5:2017
EN 1364-5:2017 (E) 10 8 Conditioning The test construction shall be conditioned in accordance with EN 1363-1. 9 Application of instrumentation 9.1 Thermocouples 9.1.1 Furnace thermocouples (plate thermometers) Plate thermometers shall be provided in accordance with EN 1363-1. There shall be at least one for every 1,5 m2 of the exposed surface area of the test construction. Plate thermometers shall be oriented so that side 'A' faces the back wall of the furnace for vertical test constructions and shall be oriented so that side 'A' faces the floor of the furnace for horizontal test constructions. At the commencement of the test the furnace shall include minimum 3 thermometers irrespective of the size of the test construction. 9.1.2 Unexposed surface thermocouples 9.1.2.1 General Several thermocouples shall be placed in order to determine the insulation criteria of the specimen. It is specified in EN 1364-1 that no thermocouples are positioned on discrete areas of less than 0,1 m2. For air transfer grilles this would imply that grilles could be classified (I) without having any thermocouples positioned. Additional thermocouples are therefore required for this test standard as described in the following. This implies that all rules regarding thermocouple positioning according to EN 1363-1 and EN 1364-1 are followed but with additional thermocouples as detailed in 9.1.2.2 in this test standard. Unexposed surface temperature measurements shall be made using thermocouples in accordance with EN 1363-1. In the case of non-planar surfaces, the disc and pad shall be deformed to follow the surface profile. If there is difficulty in fixing the standard pad, the size of the pad shall be reduced subject to a minimum diameter of 12 mm. In addition to the general rules for the attachment of thermocouples given in EN 1363-1, the selected thermocouples shall be mechanical held by an applied force of (0,3 ± 0,1) N. This additional equipment should be used if required (for example if thermocouples detaches from the test specimen during the test or immersed by intumescent material) for thermocouples located on ATG flow zone and should be limited to ATG tested without decorative covers, where the thermocouples are placed directly on the reactive parts. An example of method to apply 0,3 N is given in Figures 3 and 4. Care shall be taken how the force is applied to the thermocouple pad, to reduce heat transfer through the force application system. Also damaging of the surface of the air transfer grille should be avoided. NOTE The configuration of the load application system has only been described on a general level, to allow the laboratories to find suitable methods for the individual test. A more rigid description can be considered when the laboratories have gained more practical experience on this matter. For un-insulated air transfer grilles (only E classification) the temperature of the unexposed face is not required to be measured and no thermocouples are therefore required to be attached. Examples of location of unexposed face thermocouples are given in Figure 1. SIST EN 1364-5:2017
EN 1364-5:2017 (E) 11 9.1.2.2 Average unexposed face temperature The average temperature rise shall be measured by thermocouples evenly distributed over the air transfer grille. The average thermocouples shall be fixed onto the air transfer grille at a density depending on the grille flow zone: — Area less than 0,02 m2 = 1 thermocouples — Area equal to or larger than 0,02 m2 and less than 0,04 m2 = 2 thermocouples — Area equal to or larger than 0,04 m2 and less than 0,36 m2 = 3 thermocouples — Area equal to or larger than 0,36 m2 = 5 thermocouples The thermocouples should be located no closer than 50 mm from the edge of the air transfer grille. 9.1.2.3 Maximum unexposed face temperature 9.1.2.3.1 General The maximum temperature shall be determined from the thermocouples fixed to determine the average temperature and from thermocouples fixed according to 9.1.2.3.2 and 9.1.2.3.3. 9.1.2.3.2 Air transfer grille installed in vertical supporting construction Position one thermocouple on the air transfer grille face at midpoint of each side of the grille frame (4 thermocouples in total) and in distance 25 mm from each edge of the frame to the outside (on aperture) and inside (on ATG flow zone) direction (see Figure 1). For ATG with circular shape – thermocouple shall be placed respectively on each quadrant. When a decorative cover is used, use the same position of thermocouples but projected on to the decorative cover, with the exception for the thermocouples on the supporting construction, which should be placed 25 mm from the edge of the decorative cover to the outside direction (see Figure 2). 9.1.2.3.3 Air transfer grille installed in horizontal supporting construction Position one thermocouple on the air transfer grille face at midpoint of each side of the grille frame (4 thermocouples in total) and in distance 25 mm from each edge of the frame to the outside (on aperture) and inside (on ATG flow zone) direction (see Figure 1). For ATG with circular shape – thermocouple shall be placed respectively on each quadrant. When a decorative cover is used, use the same position of thermocouples but projected on to the decorative cover, with the exception for the thermocouples on the supporting construction, which should be placed 25 mm from the edge of the decorative cover to the outside direction (see Figure 2). 9.1.2.4 Roving thermocouple The information obtained on unexposed grille face temperatures shall be supplemented by additional data derived from measurements obtained using a roving thermocouple as specified in EN 1363-1, applied to identify any local “hot spots” or where temperatures measured by the fixed thermocouples are not reliable. The force used to apply the roving thermocouple shall be 0,3 ± 0,1 N. This additional equipment should be used if required and should be limited to ATG tested without decorative covers, where the roving thermocouple may be placed directly on the reactive parts. An example of method to apply 0,3 N is given in Figures 3 and 4. SIST EN 1364-5:2017
EN 1364-5:2017 (E) 12 Some air transfer grilles are manufactured from materials which deform or expand considerably during a fire test and often have irregular or unstable surfaces that prevent reliable thermal contact to be maintained. In these cases the use of the roving thermocouple could be recommended. If it is not possible to measure the grille face temperature of the ATG, it cannot be classified for Insulation criteria. 9.2 Pressure Pressure measuring devices shall be located in accordance with EN 1363-1. 9.3 Radiation If radiation is to be measured, radiometers shall be positioned as described in EN 1363-2. 9.4 Other equipment The cotton pad can be used to confirm that there is no fire hazard from any apparent gaps within the grille face. NOTE The nature and behaviour of air transfer grilles materials do not allow the use of gap gauges at the grille face to measure integrity, The integrity is observed by the cotton pad and by visual observations of cracks/openings through the air transfer grille. Any gaps th

Introduction
The purpose of this test is to measure the ability of a representative specimen of an air transfer grill to
resist the spread of fire from one side to another.
A representative sample of the air transfer grille is exposed to a specified regime of heating and the
performance of the test specimen is monitored on the basis of criteria given in this standard. Fire
resistance of the test specimen is expressed as the time for which the appropriate criteria have been
satisfied. The times so obtained are a measure of the adequacy of the construction in a fire but have
no direct relationship with the duration of a real fire.
Caution
The attention of all persons concerned with managing and carrying out this furnace testing is drawn to
the fact that fire testing can be hazardous and that there is a possibility that toxic and/or harmful
smoke and gases can be evolved during the test. Mechanical and operational hazards can 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 shall be made and safety precautions need
to be identified and provided. Written safety instructions need to be issued. Appropriate training needs
to be given to relevant personnel. Laboratory personnel need to ensure that they follow written safety
instructions at all times.

1 Scope
This test method specifies a method for determining the fire resistance of air transfer grilles(ATG).
It is applicable to air transfer grilles intended for installation in building components (typically walls,
floors or ceilings). The orientation of the installation of the air transfer grille can be vertical or
horizontal.
The closing mechanism of the air transfer grille can come from expansion of material and/or from any
mechanical or electrical closing device.
This test method is valid for fire resistant or fire resistant and smoke control air transfer grilles.
This test method evaluates the behaviour of the air transfer grille when exposed to the standard fire
curve described in EN 1363-1 and the standard pressure described in EN 1363-1.It is not the intention
of this test to provide quantitative information on the rate of leakage of smoke and/or hot gases or on
the transmission or generation of fumes under fire conditions. Such phenomena are only to be noted
in describing the general behaviour of test specimens during the test.
The rate of leakage of smoke at ambient temperature or at 200°C is addressed in product technical
specifications (e.g. in ETAG 026 – part 4)
All values given in this standard are nominal unless otherwise specified.
This test method is not valid for determining the fire resistance of air transfer grilles that are used in
ducts because ATG are considered as separating elements. The test method for ATG, used in ducts
is described in the corresponding duct standards.
Non-mechanical fire barriers for ventilation ductwork according to EN 1366-12 are excluded.
This test method is not valid for determining the fire resistance of air transfer grilles in fire doors,
shutters and openable windows as specified in EN 1634-1 and EN 1364-2, because the deformation
of fire doors, shutters and openable windows in fire conditions differs from the deformation of
flexible/rigid walls. Moreover the location of TC in the door standard is too specific to be handled in
this standard.

4.1 General
See EN 1363-1, and if applicable EN 1363-2.
5 Test conditions
5.1 Heating conditions
The heating conditions and the furnace atmosphere shall conform to those given in EN 1363-1 or, if
applicable, EN 1363-2.
5.2 Pressure conditions
Pressure conditions and tolerances shall be as given in EN 1363-1.
Depending on the field of application air transfer grilles installed in vertical supporting constructions
can be tested in the positive or negative pressure zone. If the grille is intended for both zones, both
scenarios should be tested.
Air transfer grilles installed in horizontal supporting constructions are always considered as being
positioned in the positive pressure zone.
The pressure during the test at the top and at the bottom of the ATG will be calculated and reported in
the test report and in the classification report. Also the corresponding height above notional floor level
of top and bottom of the ATG shall be reported.

6 Test specimen
6.1 General
The test specimen consists of an air transfer grille together with a supporting construction. In cases
where multiple test specimens are included in a single test construction they shall be the subject of a
separate evaluation.
6.2 Size
The test specimen shall be normally full size.
If modular air transfer grilles are tested, the largest assembly size shall be tested.
In order to avoid boundary effects, the distance between the perimeter of the air transfer grille and the
internal surfaces of the furnace shall be not less than 200 mm at any point.
In cases where multiple test specimens are included in a single test construction, the minimum
distance between adjacent air transfer grilles shall be not less than 200 mm.
6.3 Number
For grilles installed in vertical supporting constructions the number of test specimens required is given
in EN 1363-1.
For horizontal separating elements only one test specimen is required with fire exposure from the
underside.
For grilles that are not symmetrical, each side has to be tested.
Where an air transfer grille is intended for use both in floors and walls, the ATG shall be tested both
vertically and horizontally.
6.4 Design
6.4.1 General
The test specimen shall be fully representative of the air transfer grille used in practice, including any
special features which are unique to the grille.
The design features which influence fire performance shall be included to give the widest application,
According to the field of direct application, clause 13.
6.4.2 Restraint
The edges of the test specimen shall be restrained as in practice. The method of restraining the air
transfer grille is considered part of the test specimen.
6.5 Construction
The test specimen shall be constructed as described in EN 1363-1.
6.6 Verification
Verification of the test specimen shall be carried out as described in EN 1363-1.
