26、tee 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of an identical text or by endorsement, at the latest by March 2015 and conflicting national standards shall be withdrawn
27、 at the latest by March 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 document supersedes ENV 13381-2:2002. The main chan
28、ges with respect to the previous edition are listed below: Clarifications regarding the following items: a) preparation of the test specimen; b) instrumentation of the test specimen (no more steel plate within the cavity); c) limits of applicability. This document has been prepared under a mandate g
29、iven to CEN by the European Commission and the European Free Trade Association. This European Standard is one of a series of standards for evaluating the contribution to the fire resistance of structural members by applied fire protection materials. Other parts of the standard are: Part 1: Horizonta
30、l protective membranes, Part 3: Applied protection to concrete members, Part 4: Applied protection 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 timb
31、er members, Part 8: Applied reactive protection to steel members. The fire protection capacity of the vertical protective membrane can be nullified by the presence of combustible materials in the cavity behind the membrane. The applicability of the results of the assessment is limited according to t
32、he quantity and position of such combustible materials within that cavity. The amount of combustible material permissible in the cavity should be given in national regulations. Caution The attention of all persons concerned with managing and carrying out this fire resistance test, is drawn to the fa
33、ct 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 and the disposal of test residues.
34、 DIN EN 13381-2:2014-12 EN 13381-2:2014 (E) 5 An assessment of all potential hazards and risks to health shall be made and safety precautions shall be identified and provided. Written safety instructions shall be issued. Appropriate training shall be given to relevant personnel. Laboratory personnel
35、 shall ensure that they follow written safety instructions at all times. The specific health and safety instructions contained within this standard shall be followed. When testing concrete filled hollow steel composite columns steam release holes shall be provided for the release of steam from the c
36、olumn, during the test, as specified in EN 13381-6.

38、014 (E) 6 1 Scope This European Standard specifies a test method for determining the ability of a vertical protective membrane, when used as a fire resistant barrier, to contribute to the fire resistance (loadbearing capacity R) of loadbearing vertical structural building members fabricated from ste
39、el, concrete, steel/concrete composites or timber. The method described is applicable to any type of vertical protective membrane, which can be associated with a separate bracing membrane. The vertical protective membrane can be either separated from or attached to the structural building member and
40、 is self-supporting. This test method is applicable to vertical protective membranes where there is a gap and a cavity between the vertical protective membrane and the structural building member, otherwise alternative test methods prEN 13381-3, EN 13381-4, EN 13381-6 or prEN 13381-7 should be used a
41、s appropriate. This test method and assessment is not applicable to the following: a) all situations where the cavity is to be used as a service or ventilation shaft; b) all situations where the vertical protective membrane acts as a bracing membrane. This European Standard contains the fire test wh
42、ich specifies the tests which shall be carried out whereby the vertical protective membrane together with the structural member to be protected is exposed to the specified fire. The fire exposure, to the standard temperature/time curve given in EN 1363-1, is applied to the side which would be expose
43、d in practice. The test method makes provision, through specified optional additional procedures, for the collection of data which can be used as direct input to the calculation of fire resistance according to the processes given in EN 1992-1-2, EN 1993-1-2, EN 1994-1-2 and EN 1995-1-2. This Europea
44、n Standard also contains the assessment which provides information relative to the analysis of the test data and gives guidance for the interpretation of the results of the fire test, in terms of loadbearing capacity criteria of the protected vertical structural member. The results of the fire test
45、and the assessment can be applied, with certain defined provisions, to vertical structural building members which can be beams, columns or a combination of both and / or which could form part of a separating element or partition. The limits of applicability of the results of the assessment arising f
46、rom the fire test are defined, together with permitted direct application of the results to different structures, membranes and fittings. In special circumstances, where specified in national building regulations, there can be a need to subject the protection material to a smouldering curve. The tes
47、t for this and the special circumstances for its use are detailed in Annex B. Tests should be carried out without additional combustible materials in the cavity. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for
