Test methods for determining the contribution to the fire resistance of structural members - Part 5: Applied protection to concrete/profiled sheet steel composite member
This European Standard specifies a test method for determining the contribution of fire protection systems to the fire resistance of structural concrete/profiled sheet steel composite members or slabs. The concrete can be lightweight, normal-weight or heavy-weight concrete and of strength classes 20/25 (LC/C/HC) to 50/60 (LC/C/HC).
The test method and its assessment procedure are designed to permit direct application of the results to cover a range of thicknesses of the applied fire protection material.
The test method is applicable to all fire protection materials used for the protection of concrete/steel composite members or slab and includes sprayed materials, coatings, cladding protection systems and multi-layer or composite fire protection materials, with or without a cavity between the fire protection material and the concrete/steel composite members or slab.
This European Standard contains the fire test which specifies the tests which will be carried out to determine the ability of the fire protection system to remain coherent and fixed to the composite member and to provide data on the temperatures of the steel sheet, throughout the depth of the concrete (for extended application purposes) and the unexposed surface of the concrete, when exposed to the standard temperature/time curve according to the procedures defined herein.
In special circumstances, where specified in national building regulations, there can be a need to subject reactive protection material to a smouldering curve. The test for this and the special circumstances for its use are detailed in Annex A.
The fire test methodology makes provision for the collection and presentation of data which can be used as direct input to the calculation of fire resistance of concrete/steel composite members in accordance with the procedures given in EN 1994 1 2.
This European Standard also contains the assessment which prescribes how the analysis of the test data needs to be made and gives guidance to the procedures by which interpolation needs to be undertaken.
The limits of applicability of the results of the assessment arising from the fire test are defined, together with permitted direct application of the results to different steel/concrete composite structures, steel types and thicknesses, concrete densities, strengths, thicknesses and production techniques over the range of thicknesses of the applied fire protection system tested.

A span of 3 000 mm is mainly valid for trapezoidal decking with height of ribs of 50/60 mm and steel thickness of 1 mm. b The distance between the exposed part of the test specimen and the supports shall be kept as small as possible. For tests of short duration (less than 240 min) a distance of 100 mm at either end is recommended. For tests of longer duration, this can be increased to 200 mm at either end, to protect the test equipment from heat damage. c The additional length beyond the supports, required for installation purposes, shall be kept as small as it is practically possible. 6.3.2 Fabrication of concrete/steel composite slab test members Composite slab test members shall be prepared in a smooth surfaced framework made from steel or timber. To facilitate release of the edges of the slab from the framework, soluble oils or emulsions shall preferably be used, although wax, non-soluble oil or non-soluble emulsions may be used. The actual material used for this purpose shall be detailed in the test report. 6.3.3 Application of the fire protection system (except suspended ceiling) to the composite test slab The steel surface of the composite test element shall be prepared as in practice. The surface of the steel face of the concrete/steel composite test slab shall normally be dried prior to the application of the fire protection system. The fire protection system shall be uniformly applied to the test specimen, as in practice, including any required fixing aids and in the same manner for both maximum and minimum thickness. The fire protection material shall extend over the full exposed surface of the concrete/steel composite test slab and be applied prior to the application of the test load (if any). Where a fire protection system creates small cavities between the concrete/steel composite test element and the fire protection material, the ends shall be sealed with fire resistant material to prevent any flow of hot gases out of the cavities. Board type fire protection systems shall include joints in accordance with the following criteria: —
large size test specimen: at least one longitudinal joint shall be situated near the longitudinal mid-width axis under a void between two waves and at least one transverse joint positioned not further than 500 mm from the transverse mid-span axis; SIST EN 13381-5:2014
small size test specimen: at least one longitudinal joint shall be situated near the longitudinal mid-width axis under a void between two waves and at least one transverse joint positioned not further than 100 mm from the transverse axis. 6.3.4 Installation of the suspended ceiling onto the composite test slab The test specimen shall reproduce the conditions of use, including junctions between membrane and walls and edge panels, joints and jointing materials and be installed from below by the same method and procedures as given in the installation manual, or in written instructions, which shall be provided by the sponsor. It shall be fitted with all the components for hanging, expansion and abutting, plus any other fixtures which are to be defined by the sponsor, with a frequency representative of practice. For horizontal protective membranes which are suspended from the structural building member by hangers, the suspension system and the length of the hangers shall be representative of practice. The profiles bearing the various panels shall be installed against each other without any gap, unless a gap (or gaps) is required for design purposes. In this case the gap (or gaps) at the junctions of main runners shall be representative of that to be used in practice and shall be installed within the main runners and not at their ends. The profiles within the test specimen shall include a joint representative of joints to be used in practice in both longitudinal and transverse directions. The horizontal protective membrane shall be fixed according to normal practice on all four edges, either directly to the furnace walls or to a test frame. A test frame, where used, shall be fixed directly to the horizontal structural building member being protected, or to the furnace walls. If the construction or properties of the horizontal protective membrane are different in the longitudinal and transverse directions, the performance of the specimen may vary depending upon which components are aligned with the longitudinal axis. If known from experience, the specimen shall be installed so as to represent the most onerous condition by arranging the more critical components parallel to the longitudinal axis. If the more onerous condition cannot be identified, two separate tests shall be carried out with the components arranged both parallel and perpendicular to the longitudinal axis. 6.4 Composition of test specimen component materials 6.4.1 Profiled steel sheet The steel used shall be of grade between S280GD and S350GD as defined in EN 10346. 6.4.2 Concrete The concrete in the test specimen shall normally be of type 25/30 to 30/37 [LC/C/HC] (light-weight between 800 and 2 000 kg/m3, normal-weight between 2000 and 2600 kg/m3 or heavy-weight concrete greater than 2 600 kg/m3) according to EN 206 and EN 1992-1-1, although other grades within the strength range 20/25 to 50/60 may be used (see Clause 1). The concrete shall be prepared from silicious aggregates, of maximum aggregate size of 20 mm, and Portland cement. The composition and properties of the concrete used shall be appropriate to those defined in EN 206 and EN 1992-1-1. Other non-silicious and lower density aggregates may be permitted, but the applicability of the results of the assessment will be restricted according to 15.7. SIST EN 13381-5:2014
The thickness of a sprayed or coated passive type fire protection material shall not deviate by more than 20 % of the mean value over the whole of its surface. The mean value shall be used in the assessment of the results and the limits of applicability of the assessment. If it deviates by more than 20 %, the maximum thickness recorded shall be used in the assessment. The density of fire protection material applied to the composite steel/concrete slabs at minimum and maximum thickness shall be recorded. The average between mean values of the density of the fire protection material at minimum and maximum thickness shall be used in the assessment of the results of the test, unless the difference between this average value and the mean values at minimal and maximal thickness is greater than 15 % of the average value, in which case the maximum mean density value recorded shall be used. 6.6 Verification of the test specimen An examination and verification of the test specimen for conformity to specification shall be carried out as defined in EN 1363-1. The properties of the materials used in the preparation of the test specimen shall be measured using special samples, where necessary, as described in 6.5 using the methods defined in Annex B. The sponsor shall verify that the fire protection material has been applied correctly and in the case of sprayed or coating materials ensure, by methods appropriate to the material, that it is of the design composition and specification. 7 Installation of the test construction The test construction, comprising the concrete/steel composite test slab, any supporting construction or test frame and the fire protection system, shall be installed onto the furnace to allow freedom for longitudinal deflection and movement, according to 5.2.1, using at one side rolling support(s) and at the other side, hinge support(s). Special attention shall be given to the choice of size of the test specimen according to the expected duration of the test (see 6.2) and to insulation of the supports carrying the slab against the influence of heat. Care shall be taken to ensure during installation of the test specimens onto the furnace, or as a result of any movement occurring during the test, that the fire protection system is not subjected to any expansion or restraint stresses contrary to its use in practice. 8 Conditioning of the test construction The test construction and test samples taken for the determination of material properties (specified in 6.5) shall be conditioned according to EN 1363-1. Material properties shall be determined according to methods specified in 6.5, EN 1363-1 and Annex B. The minimum conditioning time for concrete/steel slabs shall be 90 d. SIST EN 13381-5:2014
