This European Standard shall be given the statu

23、s of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2013, and conflicting national standards shall be withdrawn at the latest by November 2013. Attention is drawn to the possibility that some of the elements of this document may be the su

24、bject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13381-8:2010. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. With resp

25、ect to the previous version, the following changes have been made: A change has been made to the test method to introduce of a means allowing loaded beams to reach a deflection of L/30. In addition the graphical assessment method now includes a point to point method of constructing lines and a new v

26、irtual data point related to furnace temperature. This document is compatible with EN 13381-4 and specifically deals with the testing and assessment of reactive coatings designed to protect structural steel. This document is part of the EN 13381 series with the general title Test methods for determi

27、ning the contribution to the fire resistance of structural members. Other parts of this series are: Part 1: Horizontal protective membranes; Part 2: Vertical protective membranes; Part 3: Applied protection to concrete members; Part 4: Applied passive protection to steel members; Part 5: Applied pro

28、tection to concrete/profiled sheet steel composite 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 (the present document). Caution The attention of all persons concerned wi

29、th 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 BS EN 13381-8:2013EN 13381-8:2013 (E) 5 operational hazards can als

30、o arise during the construction of test 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. Appropria

31、te training should be given to relevant 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 natio

32、nal standards organisations of the following 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, Lith

33、uania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 13381-8:2013EN 13381-8:2013 (E) 6 1 Scope This European Standard specifies a test method for determining the contribution made by applied rea

34、ctive fire protection systems to the fire resistance of structural steel members, which can be used as beams or columns. It considers only sections without openings in the web. It is not directly applicable to structural tension members without further evaluation. Results from analysis of I or H -se

35、ctions are directly applicable to angles, channels and T-sections for the same section factor, whether used as individual elements or as bracing. This standard does not apply to solid bar or rod. It covers fire protection systems that involve only reactive materials and not to passive fire protectio

36、n materials as defined in this document. The evaluation is designed to cover a range of thicknesses of the applied fire protection material, a range of steel sections, characterised by their section factors, a range of design temperatures and a range of valid fire protection classification periods.

37、This European Standard contains the fire test procedures, which specifies the tests which should be carried out to determine the ability of the fire protection system to remain coherent and attached to the steelwork, and to provide data on the thermal characteristics of the fire protection system, w

38、hen exposed to the standard temperature/time curve specified in EN 1363-1. 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 d

39、escribed 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 steel structural members in accordance with the procedures given in EN 1993-1-2 and EN 1994-1-2. This European Standa

40、rd also contains the assessment, which prescribes how the analysis of the test data shall be made and gives guidance on the procedures by which interpolation should be undertaken. The assessment procedure is used to establish: a) on the basis of temperature data derived from testing loaded and unloa

41、ded sections, a correction factor and any practical constraints on the use of the fire protection system under fire test conditions, (the physical performance); b) on the basis of the temperature data derived from testing short steel sections, the thermal properties of the fire protection system, (t

42、he thermal performance). 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 sections and grades and to the fire protection system. The results of the test and assessment ob

43、tained according to this standard are directly applicable to steel sections of I and H cross sectional shape and hollow sections. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
