Fire resistance tests for service installations - Part 3: Penetration seals
This document specifies a method of test and criteria for the evaluation of the ability of a penetration sealing system to maintain the fire resistance of a separating element at the position at which it has been penetrated by a service. Excluded are chimneys, air ventilation systems, fire rated ventilation ducts, fire rated service ducts, shafts and smoke extraction ducts.
Supporting constructions are used in this document to represent separating elements such as walls or floors. These simulate the interaction between the test specimen and the separating element into which the sealing system is to be installed in practice.
This document is used in conjunction with EN 1363-1.
The purpose of this test described in this document is to assess:
a) the effect of such penetrations on the integrity and insulation performance of the separating element concerned;
b) the integrity and insulation performance of the penetration sealing system;
c) the insulation performance of the penetrating service or services, and where necessary, the integrity failure of a service.
No information can be implied by the test concerning the influence of the inclusion of such penetrations and sealing systems on the loadbearing capacity of the separating element.
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. Such phenomena should only be noted in describing the general behaviour of test specimens during the test.
This test does not supply any information on the ability of the penetration sealing system to withstand stress caused by movements or displacements of the penetrating services.
Explanatory notes to this test method are given in Annex A.
Feuerwiderstandsprüfungen für Installationen - Teil 3: Abschottungen
Diese Norm legt ein Prüfverfahren fest sowie die Kriterien für die Beurteilung des Leistungsverhaltens eines Abschottungssystems, die raumabschließende und wärmedämmende Wirkung eines raumabschließenden Bauteils an dem Ort, an dem eine Installation hindurchgeführt wurde, aufrechtzuerhalten. Ausgenommen sind Abgasanlagen, Lüftungsanlagen, feuerwiderstandsfähige Lüftungsleitungen und Installationskanäle, Installationsschächte und Entrauchungsleitungen.
Raumabschließende Bauteile wie z. B. Wände oder Decken werden in dieser Norm durch den Einsatz von Tragkonstruktionen nachgestellt. Diese simulieren die Wechselwirkung zwischen dem Probekörper und dem raumabschließenden Bauteil, in welches das Abschottungssystem in der Praxis eingebaut wird.
Diese Norm gilt zusammen mit EN 1363 1.
Die in dieser Norm beschriebene Prüfung dient der Beurteilung:
der Auswirkung derartiger Durchführungen auf das raumabschließende und wärmedämmende Verhalten des betreffenden raumabschließenden Bauteils;
des Raumabschlusses und Wärmedämmverhaltens des Abschottungssystems;
des Wärmedämmverhaltens der durchlaufenden Installation(en) und erforderlichenfalls des Verlustes der raumabschließenden Wirkung einer Installation.
Die Prüfung ermöglicht keine Aussagen darüber, inwieweit das Vorhandensein derartiger Durchführungen und Abschottungssysteme einen Einfluss auf die Tragfähigkeit des raumabschließenden Bauteils ausübt.
Der Zweck dieser Prüfung besteht nicht darin, quantitative Angaben über die Leckrate von Rauch und/oder heißen Gasen oder die Übertragung bzw. Erzeugung von Rauchgasen zu ermitteln. Derartige Beobachtungen sollten nur bei der Beschreibung des allgemeinen Verhaltens der Probekörper während der Prüfung festgehalten werden.
Diese Prüfung liefert keine Angaben über das Leistungsverhalten eines Abschottungssystems, Spannungen, die durch Bewegungen oder Verschiebungen der durchlaufenden Installationen erzeugt werden, zu widerstehen.

8 4 Test equipment In addition to the test equipment specified in EN 1363-1, and if applicable EN 1363-2, the minimum internal dimensions of the furnace shall be 1 m × 1 m × 1 m. 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 5.2.1 Pressure conditions shall be as given in EN 1363-1. 5.2.2 Where there is only a single vertical penetration that has a maximum height of 1 m, a pressure of (15 ± 2) Pa shall be established at the centre of this penetration. 5.2.3 If a single vertical penetration sealing system is tested which has a height of more than 1 m, it shall be tested with a pressure of (20 ± 2) Pa at its top and in such cases penetrating services shall be included in the zone where positive pressure exceeds 10 Pa (see Figure 1). 5.2.4 If more than one penetration sealing systems is tested in a single vertical supporting construction, the pressure conditions specified in 5.2.2 or 5.2.3 shall apply to the lowest penetration. 5.2.5 For horizontal separating elements the pressure of (20 ± 2) Pa shall be maintained in the horizontal plane (100 ± 10) mm below the underside of the supporting construction. 6 Test specimen 6.1 General The test specimen consists of a single penetration sealing system together with a supporting construction. 6.2 Size A penetration and the accompanying penetration seal shall be as in practice. In order to avoid boundary effects, the distance between the perimeter of the penetration sealing system 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 penetration seals shall be not less than 200 mm. Each penetration with its associated service(s) and penetration sealing system(s) shall be the subject of a separate evaluation, provided the standard test conditions are maintained throughout the test with respect to the penetration being evaluated. 6.3 Number For vertical separating elements 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.¹) Fire from below floors is generally more critical than fire from above. However, in addition to SIST EN 1366-3:2004
EN 1366-3:2004 (E) 9 the classification requirements from below, requirements from below, requirements can also be related to the thickness and quality of the flooring /floor and its subsequent design to safeguard from above. Where a penetration sealing system is intended for use both in floors and walls, the systems shall be tested both vertically and horizontally. 6.4 Design 6.4.1 General The test specimen shall be either: a) fully representative of the service and penetration sealing system used in practice, including any special features which are unique to that installation; or b) a standard configuration (see Annexes B and C, and Table 2 or 3 for the supporting construction) which is deemed to cover a wide range of practical applications. 6.4.2 Support conditions for penetrating services The support conditions for the service(s) shall be chosen from the following: a) without support; b) standard service support construction (see Table 2 and /or 3); c) full-scale representation as in practice together with any calculation and the application of a load to simulate practical conditions. In each condition the method of support (if any) shall be fully described in the test report. 6.4.3 Pipe end configuration When pipes are to be tested, the pipe end configurations shall be chosen from Table 1.
Table 1 — Pipe end configuration Pipe end configuration Test condition Inside the furnace Outside the furnace A Uncapped Uncapped B Capped Uncapped C Uncapped Capped D Capped Capped
Capping of pipes shall be carried out by closing the pipe end by inserting a mineral wool disc of a thickness of (75 ± 10) mm and a density of (150 ± 50) kg/m3 into the end of the pipe, 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 where vertical pipes are tested, the mineral wool shall be fixed additionally by mechanical means. SIST EN 1366-3:2004
EN 1366-3: 2004 (E)
10 6.4.4 Cable end configuration The heated ends of solid elements such as electrical conductors shall be left uncapped. Cables projecting from the unheated face of the supporting construction shall be capped using an appropriate method to prevent hot gases escaping. 6.4.5 Blank penetration seal If a blank penetration seal is to be evaluated, this shall be incorporated into the supporting construction. 6.4.6 Subsequent addition of services If it is the intention of the test to represent the effect of adding extra services or altering the number and/or type of service running through the seal subsequent to installation, then the following procedure shall be followed. After installation of the first service and penetration sealing system 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 service(s) as required to be evaluated and the test construction conditioned again. Any such procedures shall be fully described in the test report. 6.5 Construction The test specimen shall be constructed as described in EN 1363-1. 6.6 Verification Verification of the test specimen(s) shall be carried out as described in EN 1363-1. 7 Installation of test specimen 7.1 General The test specimen(s) shall be installed, as far as possible, in a manner representative of their use in practice. Care shall be taken to avoid any artificial support which could be provided to the service e.g. if it sags during the test. 7.2 Supporting construction 7.2.1 General Whenever practicable, one of the standard supporting constructions given in 7.2.2 should be used. The results may be applicable to other separating elements in accordance with the field of direct application provisions in Clause 13. The supporting construction chosen for the test may be the actual construction to be used in practice. However, the result is only applicable to that form of construction, unless the form of construction in practice is one of the standard supporting constructions given in 7.2.2. SIST EN 1366-3:2004
