BS EN 1365-1:2012EN 1365-1:2012 (E) 4 Introduction The purpose of this test is to measure the ability of a representative specimen of a loadbearing wall to resist the spread of fire from one side to another and to maintain its loadbearing capacity. It is applicable to

22、 internal and external walls. Caution The attention of all persons concerned with managing and carrying out this fire resistance test is drawn to the fact that fire testing may be hazardous and that there is a possibility that toxic and/or harmful smoke and gases may be evolved during the test. Mech

23、anical and operational hazards may also arise during the construction of the test elements or structures, their testing and 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 in

24、structions should be issued. Appropriate training should be given to relevant personnel. Laboratory personnel should ensure that they follow written safety instructions at all times. BS EN 1365-1:2012EN 1365-1:2012 (E) 5 1 Scope This European Standard specifies a method of testing the fire resistanc

25、e of loadbearing walls. It is applicable to both internal and external walls. The fire resistance of external walls can be determined under internal or external exposure conditions. The fire resistance performance of loadbearing walls is normally evaluated without perforations such as doors, glazing

26、 or fire resistant ducts. If it can be demonstrated that the design of the opening is such that load is not transmitted to the perforation, then the perforation need not be tested in the loaded condition. If perforations are to be included, the effects of these will need to be separately established

27、. This test method is not applicable to non-separating loadbearing walls which, in short widths, can be tested as columns to EN 1365-4. This European Standard is used in conjunction with EN 1363-1:1999. 2 Normative references The following documents, in whole or in part, are normatively referenced i

34、sfer of fire from one side to the other 4 Test equipment 4.1 General In addition to the test equipment specified in EN 1363-1:1999, and if applicable EN 1363-2, the following is required. 4.2 Test frame A test frame designed to accommodate the test specimen and apply the required test load. Examples

35、 of test frames which may be used for this purpose are shown in Figures 1 and 2. 4.3 Loading equipment The load to the test specimen may be applied by means of loading jacks located either at the top or the bottom of the frame. Where the loading is applied by a rigid beam, it shall be of sufficient

36、stiffness to ensure uniform vertical deflection along the test specimen. Where the load is applied individually to studs within the wall the loading system shall allow for maintenance of constant load at each loading point. 5 Test conditions 5.1 Furnace atmosphere The heating and pressure conditions

37、 and the furnace atmosphere shall conform to those given in EN 1363-1:1999. 5.2 Loading and restraint The load and restraint shall conform to the requirements given in EN 1363-1:1999. 6 Test specimen 6.1 Size If, in practice, the height or width of the construction is 3 m or smaller, then that dimen

38、sion of the test specimen shall be tested at full size. If any dimension of the construction is greater than 3 m, then that dimension shall be tested at not less than 3 m. In addition to the test equipment specified in EN 1363-1, and if applicable EN 1363-2, the following is required.The heating and

39、 pressure conditions and the furnace atmosphere shall conform to those given in EN 1363-1.EN 1363-1.BS EN 1365-1:2012EN 1365-1:2012 (E) 7 6.2 Number The number of test specimens shall be as given in EN 1363-1:1999. However, where information is required under different exposure conditions additional

40、 tests shall be undertaken for each situation using separate test specimens. 6.3 Design The test specimen shall be fully representative of the construction intended for use in practice. The test specimen should be designed to obtain the widest applicability of the test result when considered in conj

41、unction with the direct and extended field of application rules. Some design features which influence fire performance that should be included can be derived from the field of direct application, see Clause 13. The test specimen shall only contain a mixture of different designs providing this is rep

42、resentative of end use applications. Where the test specimen can incorporate at least two full width boards, a full size board shall be adjacent to an edge. When it is not possible to incorporate two full size boards into the test specimen, the single full size board shall be located in the centre o

43、f the specimen, with smaller boards of equal width on each side. The smaller boards shall not be less than 500 mm wide. Where the smaller boards would be less than 500 mm wide, only one shall be used (see Figure 3). If the element incorporates horizontal joints in practice, then the test specimen sh

44、all incorporate a horizontal joint. This joint shall be located between 350 mm and 650 mm in from the top edge and shall be on the outer layer on the unexposed face. 6.4 Construction The test specimen shall be constructed as described in EN 1363-1:1999. 6.5 Verification Verification of the test spec

45、imen shall be carried out as described in EN 1363-1:1999. 7 Installation of test specimen 7.1 General The test construction shall be mounted in such a way that the whole of its exposed face (including edge conditions) shall be exposed to the heating conditions. 7.2 Supporting construction If the siz

46、e of the test specimen is smaller than the opening in the test frame then it shall be installed in the test frame using one of the following approaches: a) Where the height of the test specimen is smaller than the height of the test frame opening, a plinth shall be provided to reduce the opening to

47、the required height. b) Where the width of the test specimen is less than the opening in the test frame, the opening may be reduced with a suitable construction attached to the inside vertical faces of the test frame, but with a clearance of between 25 mm to 50 mm from the vertical edges of the test

48、 specimen. In either case above the use of a suitable construction shall not influence the overall performance of the test specimen. The number of test specimens shall be given in EN 1363-1. However, where information is required under ferent exposure conditions additional tests shall be undertaken

This gap shall be packed with a resilient non-combustible material, e.g. mineral fibre, to
