SIST EN 1366-3:2009

EN 1366:2009 (E) 6 1 Scope This Part of EN 1366 specifies a method of test and criteria for the evaluation (including field of application rules) of the ability of a penetration seal to maintain the fire resistance of a separating element at the position at which it has been penetrated by a service. Penetration seals used to seal gaps around chimneys, air ventilation systems, fire rated ventilation ducts, fire rated service ducts, shafts and smoke extraction ducts are excluded from this standard except for mixed penetration seals. The fire resistance of those services itself cannot be assessed with the methods described in this standard. Supporting constructions are used in this standard 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 European Standard is used in conjunction with EN 1363-1. The purpose of this test described in this standard 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 seal; 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 are only to be noted in describing the general behaviour of test specimens during the test. This test is not intended to supply any information on the ability of the penetration seal to withstand stress caused by movements or displacements of the penetrating services. The risk of spread of fire downwards caused by burning material, which drips through a pipe downwards to floors below, cannot be assessed with this test. Explanatory notes to this test method are given in Annex H. All dimensions given without tolerances are nominal ones unless otherwise stated. 2 Normative references

Services shall only be included in the zone where the positive pressure exceeds 10 Pa (a minimum pressure of 10 Pa shall be maintained at the lowest point of the lowest service, see Figure 2). NOTE A pressure of 10 Pa is expected to be maintained ca. 1200 mm below the plane where a pressure of 20 Pa is maintained according to the pressure gradient given in EN 1363-1. 5.2.3 In case of a blank penetration seal in a vertical supporting construction a minimum pressure of 20 Pa shall be maintained at the top of the seal. 5.2.4 For horizontal supporting constructions a nominal pressure of 20 Pa shall be maintained in the horizontal plane (100 ± 10) mm below the underside of the supporting construction. SIST EN 1366-3:2009

EN 1366:2009 (E) 12 6 Test specimen 6.1 Size and distances 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 seal and the internal surfaces of the furnace shall be not less than 200 mm at any point. In cases where several test specimens are included in a single test construction, the minimum distance between adjacent penetration seals shall be not less than 200 mm unless it is the intention to demonstrate that a smaller distance does not have a negative effect on fire performance. Each penetration seal 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. 6.2 Number See EN 1363-1. For horizontal separating elements only one test specimen is required with fire exposure from the underside. Where a penetration seal is intended for use both in floors and walls, the systems shall be tested both vertically and horizontally. 6.3 Design 6.3.1 General The test specimen shall be either: a) fully representative of the service and penetration seal used in practice, including any special features which are unique to that installation or b) a standard configuration which is deemed to cover a wide range of practical applications. For standard configurations or advice for designing the specimen/test setup see the following: 1) Supporting construction: 7.2.2; 2) Large cable penetration seals: Annex A; 3) Small penetration seals: Annex B; 4) Modular systems and cable boxes: Annex C; 5) Bus bars: Annex D; 6) Pipe penetration seals: Annex E; 7) Mixed penetration seals: Annex F; 8) Critical pipe/cable approach: Annex G. 6.3.2 Penetrating services For the purpose of this standard the following grouping applies: SIST EN 1366-3:2009

b) Trunking of class A1 according to EN 13501-1 with a melting or decomposition point greater than 1000°C (e.g. steel, cast iron, copper and copper alloys, nickel alloys) either insulated or non-insulated, hereafter referred to as "metal trunking". Included in this group are the above trunkings with a coating provided the overall classification is minimum A2 according to EN 13501-1.
c) Pipes, trunking and conduits of class A1 or A2 according to EN 13501-1 with a melting or decomposition point equal to or less than 1000°C (e.g. lead, aluminium and aluminium alloys) and/or the risk of fracture (glass, fibre cement) either insulated or non-insulated. d) Pipes not classified to A1 or A2 according to EN 13501-1 (e.g. made from thermoplastic or thermosetting material) including non-homogeneous materials (e.g. glass fibre reinforced plastic pipes or layered pipes), either insulated or non-insulated, hereafter referred to as "plastic pipes". e) Trunking and conduits not classified to A1 or A2 according to EN 13501-1 (e.g. made from thermoplastic or thermosetting material) including non-homogeneous materials, either insulated or non-insulated, hereafter referred to as "plastic trunkings" and "plastic conduits". 6.3.3 Support conditions for penetrating services 6.3.3.1 General The support conditions for the service(s) shall be chosen from the following: a) without support; b) standard service support construction (see Figures A.2, A.3A, A.3B, A.4, A.5, A.6, A.8 and E.10); c) full-scale representation as in practice. A load may be applied to simulate practical conditions. In each condition the method of support (if any) shall be fully described in the test report. 6.3.3.2 Standard service support construction The standard support construction for cables shall comprise of steel H-studs, steel brackets, steel rod, steel ladders and trays as shown in Figure A.2, A.4 and A.6 for vertical test specimens, of steel angles, steel channels and steel ladders as shown in Figure A.3A, A.3B and A.5 for horizontal specimens. A single or a pair of horizontal supports (20 mm steel rod) may be used on each face. Alternative constructions for the H-studs, steel brackets, steel angels and steel channels may be used (see Figure A.8 for cable supports and Figure E.10 for pipe supports).
When installing a steel ladder, positioning of a rung within the penetration seal should be avoided. Alternative materials for cable ladders/trays, e.g. plastic, aluminium, steel with organic coatings resulting in an overall class of B to E according to EN 13501-1, shall be tested in addition to the standard ladders/trays as defined in Annex A with the cables from cable tray 1 as shown in Figure A.1. The standard support for pipes shall consist of a strut / channel system with e.g. a steel band or pipe rings either standing on or hanging from the channel (see Figure E.10) to prevent movement in the plane of the supporting construction and perpendicular to the supporting construction. SIST EN 1366-3:2009

EN 1366:2009 (E) 14 In the case of flexible floor constructions the service support construction shall be independent of the supporting construction to allow differential movement of the services relative to the supporting construction. 6.3.4 Pipe end configuration When pipes are to be tested, the pipe end configurations shall be chosen from Table 2 depending on the nature of the pipe material and the required field of application.
Table 2 — Pipe end configuration Test condition Pipe end configuration Inside the furnace Outside the furnace U/U Uncapped Uncapped C/U Capped Uncapped U/C Uncapped Capped C/C Capped Capped
Capping of pipes shall be carried out by closing the pipe end by inserting an appropriate mineral wool disc into the end of the pipe, fixed in place with an appropriate adhesive (e.g. sodium silicate adhesive). For further explanation see Annex H. In cases where vertical pipes are tested, the mineral wool shall be fixed additionally by mechanical means. For “metal pipes” the pipe may be capped by fixing a disc or cap (with a melting or decomposition point equal or greater than that of the pipe) onto the end of the pipe. For “plastic pipes”, "plastic conduits” and “plastic trunkings” the pipe may be capped using a plastic cap.
Where a flue gas recovery system is intended to be used the following rules shall be obeyed: 1) Maximum 4 pipes of a comparable diameter, i.e. mean value ± 20% (for further explanation see H.4.2.3), at the same horizontal level shall be connected to one recovery pipe made from a metallic folded spiral-seam tube of 100 mm diameter. Appropriate bushings shall be used to connect the pipes to the recovery pipe; 2) The length of the recovery pipe outside the furnace shall be 1,5 ± 0,1 m (for further explanation see H.4.2.3). For relation between the use of a flue gas recovery system and the pipe end configuration see Annex E. 6.3.5 Cable end configuration The heated ends of cables shall be left uncapped. Cables projecting from the unheated face of the supporting construction shall be capped using an appropriate method, e.g. acrylic sealants, to prevent hot gases escaping. 6.3.6 Blank penetration seal If a blank penetration seal is to be evaluated, this shall be incorporated into the supporting construction. To gain the maximum field of application the largest envisaged penetration seal shall be tested. SIST EN 1366-3:2009

7.2.2.1.2 Flexible wall constructions The standard supporting construction shall be in accordance with the provisions given in EN 1363-1, subject to the following:
1) The size of the supporting construction shall be minimum 3 m in height and minimum 1,20 m in width. The flexible wall shall contain minimum 1 vertical joint between the boards; SIST EN 1366-3:2009

EN 1366:2009 (E) 16 2) The wall shall be restrained only on the top and bottom edge; 3) The number and thickness of the gypsum board(s) shall be as given in Table 3; 4) A construction including insulation shall be used. The insulation material shall be mineral wool with a classification of A1 or A2 according to EN 13501-1. The density of the insulation shall be 45 ± 15 kg/m3 for a desired fire resistance up to and including 60 min and 100 ± 15 kg/m3 for a fire resistance of more than 60 min. The thickness shall be such that the remaining gap between the board and the insulation is maximum 15 mm; 5) Demonstration of performance of a penetration seal that does not require an aperture framing may be shown by using an insulated flexible wall construction where the insulation is removed to a depth of 100 mm around the seal provided a minimum of 100 mm of insulation is left along the studs; 6) Steel studs of varying widths may be used to fit the flexible wall constructions defined in Table 3; 7) Provisions shall be made to ensure that the H-studs shown in Figure A.6 do not restrain movement of the flexible wall construction during the fire resistance test. A distance of 100 mm is considered to be appropriate. The fixing on the lower end shall be slotted to allow elongation and to avoid distortion; 8) Where the test sponsor’s penetration seal system requires the cavity of the supporting wall around the penetration to be capped, this should be accomplished in accordance with the test sponsor’s specification. The test result obtained is then only valid when used in conjunction with this capping detail. Table 3 — Standard flexible wall constructions
