27、(E) 5 Foreword This document (EN 13381-3:2015) 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 endorsemen

28、t, at the latest by October 2015 and conflicting national standards shall be withdrawn at the latest by October 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying

29、 any or all such patent rights. This document supersedes ENV 13381-3:2002. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of 89/106/EEC. The dimension tolerances regarding the manufa

30、cturing of the specimen indicated in the ENV 13381-3:2002 led to tensile stress values of 290 +/- 30 N/mm in the reinforcement bars depending on the type of structural member. In order to harmonize the mechanical constraint applied on the structural member, the bending moment has been modified to pr

31、oduce the same tensile stress on reinforcement bars equal to 300 N/mm. This value is corresponding to 60 % of the grade of the steel to be used. Due to this approach, the result of tests carried out according to ENV 13381-3:2002 can be taken into account for assessment according to the present docum

32、ent. In comparison with ENV 13381-3:2002, the following significant changes have been made: the bending moment has been modified to be adapted to the thickness of the slab; the location of thermocouple used within beams for the calculation of equivalent thickness of concrete is now at 25 mm away fro

33、m the beam bottom corner instead of 55 mm; the graphs to be used for the determination of equivalent concrete thickness for slabs has been improved and extended and is directly available in the standard. This European Standard is one of a series of standards for evaluating the contribution to the fi

34、re resistance of structural members by applied fire protection materials. The other parts of this standard are: Part 1: Horizontal protective membranes Part 2: Vertical protective membranes Part 4: Applied protection to steel members Part 5: Applied protection to concrete/profiled sheet steel compos

35、ite members Part 6: Applied protection to concrete filled hollow steel columns Part 7: Applied protection to timber members Part 8: Applied reactive protection to steel members Annexes A, B and C are normative. BS EN 13381-3:2015EN 13381-3:2015 (E) 6 Caution: The attention of all persons concerned w

36、ith managing and carrying out this fire resistance test 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 test

37、elements or structures, their testing and the 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

38、personnel. Laboratory personnel should ensure that they follow written safety instructions at all times. The specific health and safety instructions contained within this standard should be followed. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the follo

39、wing 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, N

BS EN 13381-3:2015EN 13381-3:2015 (E) 7 1 Scope This European Standard specifies a test method for determining the contribution of fire protection systems to the fire resistance of struct

41、ural concrete members, for instance slabs, floors, roofs and walls and which can include integral beams and columns. The concrete can be lightweight, normal weight or heavyweight concrete and of all strength classes (e.g. 20/25 to 50/60 for normal strength concrete and for high strength concrete 55/

42、67 to 90/105). The member is to contain steel reinforcing bars. The test method is applicable to all fire protection materials used for the protection of concrete members and includes sprayed materials, reactive coatings, cladding protection systems and multi-layer or composite fire protection mater

43、ials, with or without a gap between the fire protection material and the concrete member This European Standard specifies the tests which are to be carried out to determine the ability of the fire protection material to remain coherent and fixed to the concrete and to provide data on the temperature

44、 distribution throughout the protected concrete member, when exposed to the standard temperature time curve. In special circumstances, where specified in national building regulations, there can be a need to subject the protection material to a smouldering curve. The test for this and the special ci

45、rcumstances 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 members in accordance with the procedures given in EN 1992-1-2. This European Sta

46、ndard also contains the assessment which prescribes how the analysis of the test data is to be made and gives guidance to the procedures by which interpolation is to be undertaken. The limits of applicability of the results of the assessment arising from the fire test are defined together with permi

47、tted direct application of the results to different concrete structures, densities, strengths, thicknesses and production techniques over the range of thicknesses of the applied fire protection system tested. The test method, the test results and the assessment method are not applicable to structura

48、l hollow concrete members. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
