The work of preparing

23、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 organizations, governmental and non-governmental, in liaiso

24、n 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 given in the ISO/IEC Directives, Part 2. The main task of tec

25、hnical 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 75 % of the member bodies casting a vote. Attention is dra

26、wn 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 12567-2 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the built environme

27、nt, Subcommittee SC 1, Test and measurement methods. ISO 12567 consists of the following parts, under the general title Thermal performance of windows and doors Determination of thermal transmittance by hot box method: Part 1: Complete windows and doors Part 2: Roof windows and other projecting wind

28、ows. EN ISO 12567-2:2005vIntroduction This part of ISO 12567 should be read together with ISO 12567-1:2000 Thermal performance of windows and doors Determination of thermal transmittance by hot box method Part 1: Complete windows and doors. These two parts were jointly developed by ISO and CEN. They

29、 are designed to provide standardised thermal transmittance test values, to enable product comparisons to be made. ISO 12567-1:2000 specifies standardised specimen sizes and applied test criteria. It is recognised that the thermal performance of products will vary with heat flow direction and so it

30、is preferable to test these products at the orientation in which they will be installed. However, as there are only a few hot boxes capable of carrying out such measurements, this measurement procedure specifies that it is acceptable to measure the thermal transmittance of roof windows mounted verti

31、cally to facilitate the fair comparison of products. It should be noted that measurements with the specimen mounted vertically will generally produce U-values lower than those measured at other orientations with heat flow up. An alternative to measuring at the actual orientation that will be used in

32、 practice is to carry out calculations of convective and radiant heat transfer using the procedures specified in ISO 15099, ISO 10077-1, ISO 10077-2 and EN 673. EN ISO 12567-2:2005blank1Thermal performance of windows and doors Determination of thermal transmittance by hot box method Part 2: Roof win

33、dows and other projecting windows 1 Scope This part of ISO 12567 specifies a method to measure the thermal transmittance of roof windows and projecting windows. It does not include: edge effects occurring outside the perimeter of the specimen; energy transfer due to solar radiation on the specimen;

34、effects of air leakage through the specimen. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any am

37、ce of the building envelope EN ISO 12567-2:20052 3.2 roof windows any framed glazed product installed in a sloped or horizontal building envelope NOTE 1 Roof windows are treated as projecting windows. NOTE 2 See also Reference 1 in Bibliography. 4 Principle This part of ISO 12567 is based on a measu

38、rement procedure for roof windows and other projecting windows, in accordance with the procedure specified in ISO 12567-1:2000, except for the deviations specified below: the window is installed in the surround panel flush to the cold side (insert- or kerb-mounted as shown in Figure 1), to reflect t

39、he installation in practice; the calibration procedure and the specimen tests shall be carried out at the same orientation; for practical reasons, vertical mounting of the specimen is acceptable for product declaration purpose. Although the evaluation of the thermal performance of these types of pro

40、ducts will be made for a variety of reasons, it is important that when measurements are made for purposes of product comparison, they are carried out at the same orientation. NOTE For building load or energy calculations, the value may be corrected for the effect of the sloped glazing position using

41、 suitable national procedures. 5 Requirements for test specimens and apparatus 5.1 General The construction and operation of the apparatus shall comply with the requirements specified in ISO 8990:1994 except where modified by ISO 12567-1:2000 and this document. 5.2 Test specimen location The test sp

42、ecimen shall be mounted in the surround panel aperture according to the manufacturers instructions. If the method of installation of the roof window in the hot box cannot be unambiguously determined from the manufacturers installation instructions, the window shall be installed as shown in Figure 1.

43、 Flashings and/or kerb (curb) shall be included as the windows are normally installed (see Figure 1). NOTE Kerb and curb are synonymous.
