21、l performance of buildings and building components. Annexes A and B are normative. Annex C is informative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republi

23、 12412-4:2003 (E) 4 Introduction The method described in this European Standard provides data that can be used for calculating the overall thermal performance of windows and doors equipped with roller shutters according to EN ISO 10077-1, Thermal performance of windows, doors and shutters Calculatio
24、n of thermal transmittance Part 1: Simplified method (ISO 10077-1:2000). 1 Scope This European Standard specifies a method, based on EN ISO 8990 and EN ISO 12567-1, to measure the overall thermal transmittance of a roller shutter box in a hot box. This includes all effects of geometrical and materia
25、l characteristics in a test specimen. Edge effects occurring outside of the perimeter of the specimen are excluded. Furthermore, energy transfer due to solar radiation is not taken into account, and air leakage is excluded. The method is designed to provide both standardised tests which enable a fai
26、r comparison of different products to be made, and specific tests on products for practical application purposes. The former includes window standardised specimen sizes and applied test criteria. The determination of the overall thermal transmittance is performed for conditions which will correspond
27、 to a similar situation of the roller shutter box in practice. Information on the design of the calibration transfer standard is given in EN ISO 12567-1. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative refe
28、rences are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

Depending on the height of the box, roller shutter boxes located in pairs of
38、 the same type of construction equipped with masks (simulation of window frames) form the test specimen. The surround panel is used to keep the specimen in position. It is constructed with outer dimensions of appropriate size for the apparatus, having an aperture to accommodate the specimen (see Fig
39、ures 1 and 2). The principal heat flows through the surround panel and the calibration panel (or test specimen) are shown in Figure 3. The boundary edge heat flow due to the location of the calibration panel in the surround panel is determined separately by a linear thermal transmittance . The proce
40、dure in this standard includes a correction for the boundary edge heat flow, so that standardized and reproducible thermal transmittance properties are obtained. The magnitude of the boundary edge heat flow as a function of geometry, calibration panel thickness and thermal conductivity is determined
41、 by tabulated values given in annex B. 5 Requirements for test specimen and apparatus 5.1 General The test apparatus shall conform to the requirements specified in EN 1946-4, EN ISO 8990 and EN ISO 12567-1. 5.2 Surround panels For details see 5.2 of EN ISO 12567-1:2000. 5.3 Specimen requirements and
42、 location The roller shutter boxes shall be at least 1230 mm long and shall be mounted horizontally in the aperture (see Figure 1). For test specimens with metallic-bare surfaces, the inner and outer surfaces should be treated by coating in order to achieve an emissivity of at least 0,8. Any variati
43、ons from this value have to be justified. Adjacent roller shutter boxes located in pairs lying on top of each other are separated by insulating panels (infill elements). These panels shall be made from material with thermal conductivity less than 0,035 W/(mK) and shall be at least 150 mm high and 60
44、 mm thick. The thermal conductivity of the insulating infill elements shall be obtained by measurement according to EN 12664 (guarded hot plate apparatus) or by using panels with certified properties from an accredited source. Thermocouples to measure the surface temperature shall be placed as shown
45、 in Figure 2. For further information refer to EN ISO 12567-1.

46、ll element)6Cold side Figure 1 Roller shutter boxes in surround panel It is important that this infill element is located in the same position as the window shutter box would be in practice. The surround panel shall always be thicker than the depth of the shutter box so that the shutter box does not
47、 protrude on either side. The roller shutter boxes shall be tested as used in practice during the night-time, i.e. with roller shutters rolled down.

48、all be shortened to the last 4 to 7 slats. The last slat of each shutter box shall be taken to the outside and taped to the insulating panel. If the specimen area forms less than 30 % of the aperture area of the hot-box, two or more shutter boxes shall be installed so that the total specimen area is
49、 at least 30 % of the aperture area, with at least 150 mm between the pair of shutter boxes (see Figure 1). 5.4 Calibration panels The calibration panel shall be mounted as shown in Figure 3.
