T
26、his 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of an identical text or by endorsement, at the latest by November 2013, and conflicting national standards shall be withdrawn at the latest by November 2013. Attention is drawn to the possibility that some
27、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 document supersedes EN 13381-8:2010. This document has been prepared under a mandate given to CEN by the European Commission and
28、the European Free Trade Association. With respect 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
29、point method of constructing lines and a new virtual 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 w
30、ith the general title Test methods for determining 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 pr
31、otection to steel members; Part 5: Applied protection 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). Cau
32、tion The attention of all persons concerned with 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 DIN EN 13381-8:2013-0
33、8 EN 13381-8:2013 (E) 4operational hazards can also 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. Writt
34、en safety instructions should be issued. Appropriate 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
35、to the CEN-CENELEC Internal Regulations, the national 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, Gree
36、ce, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. DIN EN 13381-8:2013-08 EN 13381-8:2013 (E) 5 1 Scope This European Standard specifies a test meth
37、od for determining the contribution made by applied reactive 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
38、further evaluation. Results from analysis of I or H -sections 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 on
39、ly reactive materials and not to passive fire protection 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
40、range of valid fire protection classification periods. 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 t
41、hermal characteristics of the fire protection system, when 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 f
42、or this and the special circumstances for its use are described 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 giv
43、en in EN 1993-1-2 and EN 1994-1-2. This European Standard 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
44、 temperature data derived from testing loaded and unloaded 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, t
45、he thermal properties of the fire protection system, (the 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 prote
46、ction system. The results of the test and assessment obtained 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 an
