本欧洲标准规定了一种基于EN ISO 8990和EN ISO 12567-1的方法，用于测量热箱中卷帘箱的整体热传导率。这包括测试样品中几何和材料特性的所有影响。 不包括在样品周边以外发生的边缘效应。此外，不考虑太阳辐射的能量传递，并且不排除空气泄漏。 该方法旨在提供两种标准化测试，能够对不同产品进行公平比较，以及针对实际应用目的对产品进行特定测试。前者包括窗口标准样本尺寸和应用测试标准。 对于实际上对应于卷帘盒类似情况的条件，执行总体热透射率的确定。 有关校准传输标准设计的信息，请参见EN ISO 12567-1

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 material 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 fair 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 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.
