10、andards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International o

11、rganizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules giv

12、en in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least

13、75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3009 was prepared by Technical Committee ISO/TC 92, Fir

ISO 3009:2003(E) ISO 2003 All rights reserved vIntroduction This International Standard contains specific requirements for fire resistance te

15、sting which are unique to glazed elements used in building construction. The requirements for these glazed elements are intended to be applied, as appropriate, in conjunction with the detailed and general requirements given in ISO 834-1.

16、served 1Fire-resistance tests Elements of building construction Glazed elements SAFETY PRECAUTIONS 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

17、 harmful smoke and gases could be evolved during the test. Mechanical and operational hazards can 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 shall be made and safety p

18、recautions shall be identified and provided. Written safety instructions shall be issued. Appropriate training shall be given to relevant personnel. Laboratory personnel shall ensure that they follow written safety instructions at all times. 1 Scope This International Standard provides a test method

19、 for determining and assessing the fire resistance performance of both insulated and uninsulated glazed elements of building construction, when those elements are exposed to heating on one face. It is applicable to glazed separating elements such as screens, walls of glass blocks and other light-tra

20、nsmitting assemblies used in vertical, inclined or horizontal orientations, and to all separating elements containing glazing intended to be assessed in accordance with ISO 834-1 except for doors and shutter assemblies, which are intended to be tested in accordance with ISO 3008. It is directly appl

21、icable to planar elements, but also gives guidance on the testing of non-planar elements such as pyramids. The application of the test results to other, untested, forms of construction is acceptable only when the construction complies with the field of direct application given in this International

22、Standard or when it is subjected to a field of extended application analysis in accordance with ISO/TR 12470. NOTE Since ISO/TR 12470 gives only general guidelines, specific extended application analyses are to be performed only by persons expert in fire-resistant constructions. 2 Normative referenc

37、est equipment shall be as specified in ISO 834-1. The furnace used will be related to the orientation of the test specimen. For vertical specimens, the wall testing furnace is suitable; for horizontal specimens the floor furnace is applicable; for inclined specimens, either of these may be used depe

It shall be designed so that it possesses sufficient stiffness in relation to the test construction. The rigidity of the test frame shall be evaluated by

39、applying an expansion force within the frame mid-way between two opposite members of the frame and measuring the increase in the internal dimensions at these positions. This ISO 3009:2003(E) ISO 2003 All rights reserved 5evaluation shall be conducted in both directions of the frame and the increase

40、of the internal dimension shall be measured. The increase in the internal dimensions of the test frame shall not exceed 5 mm with an applied force of 25 kN. For tests on inclined elements, the furnace could need to be altered to allow for the test specimens installation. In these cases, the thermal

The orientation of th

46、e specimen shall be based on how the glazed element is to be used in practice i.e. fire exposure from above or below. 6.2 Number of specimens 6.2.1 For vertical elements, the number of specimens shall follow the general principle of ISO 834-1. 6.2.2 For horizontal or inclined elements, tests shall b

NOTE For inclinations between 0

48、 and 45, fire exposure from above is not covered by this International Standard. 6.3 Size of specimen For specimens tested in a vertical furnace, the specimen size shall be full-size when the construction is in practice less than 3 m high or 3 m wide. For larger elements that can be accommodated in

49、at least a 3 m by 3 m furnace, the minimum specimen size exposed to the heating shall not be less than 3 m 3 m. For specimens tested in a horizontal furnace, the exposed dimensions of the test specimen shall be at least 4 m 3 m, unless the construction it represents is designed to have exposed dimensions of less than 4 m 3 m, in which case the actual size shall be tested. 6.4 Test construction 6.4.1 General Where the test specimen is the same size as the opening in t
