The work of preparing International Sta
22、ndards 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 liaison with ISO, also
23、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 technical committees
24、 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 drawn to the possibi

28、11vIntroduction The method specified in this part of ISO 12567 is based on ISO 8990. It is designed to provide both standardized tests, which enable a fair comparison of different products to be made, and specific tests on products for practical application purposes. The former specifies standardize
29、d specimen sizes and applied test criteria. The determination of the aggregate thermal transmittance is performed for conditions which are similar to the actual situation of the window and door in practice.

It is applicable to all effects of frames, sashes, shutters, bl
31、inds, screens, panels, door leaves and fittings. It is not applicable to edge effects occurring outside the perimeter of the specimen, energy transfer due to solar radiation on the specimen, effects of air leakage through the specimen, and roof windows and projecting products, where the external fac
32、e projects beyond the cold side roof surface. NOTE For roof windows and projecting units, see the procedure given in ISO 12567-2.

47、 or guarded hot-box method in accordance with ISO 8990. The determination of the thermal transmittance involves two stages. Firstly, measurements are made on two or more calibration panels with accurately known thermal properties, from which the surface coefficient of the heat transfer (radiative an
48、d convective components) on both sides of the calibration panel with surface emissivities on average similar to those of the specimen to be tested and the thermal resistance of the surround panel are determined. Secondly, measurements are made with the window or door specimens in the aperture and th
49、e hot-box apparatus is used with the same fan settings on the cold side as during the calibration procedure. The surround panel is used to keep the specimen in a given position. It is constructed with outer dimensions of appropriate size for the apparatus, having an aperture to accommodate the specimen (see Figures 1 to 4). The principal heat flows through the surround panel and the calibration panel (or test specimen) are shown
