This European Standard shall be given the status of

23、 a national standard, either by publication of an identical text or by endorsement, at the latest by December 2015, and conflicting national standards shall be withdrawn at the latest by December 2015. Attention is drawn to the possibility that some of the elements of this document may be the subjec

24、t of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This European Standard is one of a series of standards

25、for evaluating the contribution to the fire resistance of structural members by applied fire protection materials. 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 p

26、rotection to steel members; Part 5: Applied protection to concrete/profiled sheet steel composite member; Part 6: Applied protection to concrete filled hollow steel columns; Part 7: Applied protection to timber members currently at Enquiry stage; Part 8: Applied reactive protection to steel members.

27、 The document adopts the principle of establishing ratios of temperatures between and around openings in the web of a beam with the temperatures of a solid portion of that beam. This is with the intention that this data can be utilized within a structural model to derive the value and location of th

28、e associated limiting temperature of the beam at the fire limit state. This can then be used in conjunction with data for the fire protection material determined from either EN 13381-4 or EN 13381-8, as appropriate to determine the necessary thickness of fire protection. According to the CEN/CENELEC

29、 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, Greece, Hungary, Icela

EN 13381-9:2015 (E)DIN EN 13381-9:2015-095 Introduction The European Committee for Standardization (CEN) draws atte

31、ntion to the fact that it is claimed that compliance with this document may involve the use of a patent concerning the method of designing a fire resistant structural beam. CEN takes no position concerning the evidence, validity and scope of this patent right. The holder of this patent right has ens

32、ured CEN that, through appropriate declaration, he/she agrees to publically disclose the relevant part of their patent in RT1356 or EN 13381-9 and renounce to challenge the same and all subsequent European standards on the basis of infringement of their patent. In this respect, the statement of the

33、holder of this patent right is registered with CEN. Information may be obtained from: Fabsec Limited 1st Floor Unit 3 Calder Close Calder Business Park Wakefield WF4 3BA United Kingdom Attention is drawn to the possibility that some of the elements of this document may be the subject of patent right

34、s other than those identified above. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. CEN (http:/www.cen.eu/cen/WorkArea/IPR/Pages/default.aspx) and CENELEC (http:/www.cenelec.eu/membersandexperts/toolsandapplications/index.html) maintain on-line lists

35、of patents relevant to their standards. Users are encouraged to consult the lists for the most up to date information concerning patents. Caution: 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

36、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 and the disposal of test residues. An assessment of all potential hazards

37、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 ensure that they follow written safety instructions at all times. The spe

38、cific health and safety instructions contained within this standard should be followed. EN 13381-9:2015 (E)DIN EN 13381-9:2015-096 1 Scope This European Standard specifies a test and assessment method for determining the contribution made by fire protection systems to the fire resistance of structur

39、al steel beam I and H members in the horizontal plane containing openings in the web which may affect the structural performance of the beam. This European Standard applies to beams subject to 3 or 4 sided fire exposure. For any beam with a single web opening or where the web openings are considered

40、 to be of small diameter in relation to the web depth the applicability of this European Standard needs to be determined by a structural engineer. This European Standard applies to fire protection materials that have already been tested and assessed in accordance with EN 13381-4 or EN 13381-8. i.e.

41、this European Standard cannot be used in isolation. Use of this European Standard requires the multi-temperature analysis (MTA) derived from EN 13381-4 or EN 13381-8 as the basis for determining thickness for beams with web openings. This MTA needs to be carried out on the web and bottom flange sepa

42、rately generating an elemental multi-temperature analysis (EMTA). The bottom flange EMTA may be used as the top flange EMTA when a beam is subject to 4 sided exposure. This European Standard contains the fire test methodology, which specifies the tests which need to be carried out to provide data on

43、 the thermal characteristics of the fire protection system, when exposed to the standard temperature/time curve specified in EN 1363-1. This European standard also contains the assessment, which prescribes how the analysis of the test data should be made and gives guidance on the procedures which sh

44、ould be undertaken. The assessment procedure is used to establish: a) on the basis of the temperature data derived from testing unloaded steel sections, the thermal response of the fire protection system on cellular beams (the thermal performance); b) the temperature ratio between the web post and t

45、he web reference temperature, which will vary depending on the web post width; c) the temperature ratio between points around the web openings and the web reference area; d) the elemental multi temperature analysis from either EN 13381-4 or EN 13381-8 needs to be reassessed and reported against elem

46、ental A/V for each fire resistance period; e) a structural model needs to be used to derive limiting temperatures for cellular beams using the data from b), c) and d) above.
