32、5) 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 October 2015 and conflic

33、ting national standards shall be withdrawn at the latest by October 2015.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 any or all such patent rights. This documen

34、t 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 manufacturing of the specimen indicated in the ENV

35、 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 produce the same tensile stress on reinforceme

36、nt 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 document. In comparison with ENV 13381-3:2002, th

37、e 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 from the beam bottom corner instead of 55 mm; t

38、he 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 fire resistance of structural members by appli

39、ed 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 composite members Part 6: Applied protection to co

40、ncrete 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. DIN EN 13381-3:2015-06 EN 13381-3:2015 (E) 6 Caution: The attention of all persons concerned with managing and carrying out this fire

41、 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 elements or structures, their testing a

42、nd 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 personnel. Laboratory personnel should

43、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 following countries are bound to implement t

DIN EN 13381-3:2015-06 EN 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 structural concrete members, for instanc

46、e 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 55/67 to 90/105). The member is to co

47、ntain 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 materials, with or without a gap betwee

48、n 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 distribution throughout the prote

49、cted 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 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 members in accordance with the procedures gi
