16、(E) iv I SO 3002 All irhgts seredevrForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body i

17、nterested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechn

18、ical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by th

19、e technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 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

20、. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3009 was prepared by Technical Committee ISO/TC 92, Fire safety, Subcommittee SC 2, Fire containment. This second edition cancels and replaces the first edition (ISO 3009:1976), which has been technically revised.

21、 BSISO3009:2003IS:9003 O3002(E) I SO 3002 All irhgts seredevr vIntroduction This International Standard contains specific requirements for fire resistance testing which are unique to glazed elements used in building construction. The requirements for these glazed elements are intended to be applied,

22、 as appropriate, in conjunction with the detailed and general requirements given in ISO 834-1. BSISO3009:2003blank BSISO3009:2003INTENRATIONAL TSANDADR IS:9003 O3002(E)I SO 3002 All irhgts seredevr 1Fire-resistance tests Elements of building construction Glazed elements SAFETY PRECAUTIONS The attent

23、ion 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 could be evolved during the test. Mechanical and operational hazards can also arise

24、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 precautions shall be identified and provided. Written safety instructions shall be issued. Appropriate trainin

25、g 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 for determining and assessing the fire resistance performance of both insulated and uninsulated glazed eleme

26、nts 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-transmitting assemblies used in vertical, inclined or horizontal orientations, and to all separating elements co

27、ntaining 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 applicable to planar elements, but also gives guidance on the testing of non-planar elements such as pyramids. Th

28、e 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 Standard or when it is subjected to a field of extended application analysis in accordance with ISO/TR 12470.

29、 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 references The following referenced documents are indispensable for the application of this document.

The furnace us

44、ed 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 depending upon the anticipated exposure conditions. A test frame or

45、supporting construction is required for the mounting or erection of the specimen. 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 applying an expansion force within the frame mid-way between two

46、 opposite members of the frame and measuring the increase in the internal dimensions at these positions. This BSISO3009:2003IS:9003 O3002(E) I SO 3002 All irhgts seredevr 5evaluation shall be conducted in both directions of the frame and the increase of the internal dimension shall be measured. The

47、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 properties of the furnace extensions shall be equ

48、ivalent to those of the furnace. See Figure 3 for an example of inclined sample installation.
