该欧洲标准规定了一种基于EN ISO 8990和EN ISO 12567-1的方法,用于测量窗户和门的框架和窗扇部件的热透过率,包括竖框和横梁。
包括门或门组件(手柄,铰链,关闭装置等)的热桥接效应。
测试程序旨在考虑框架或窗框表面的整个开发区域,但不包括通过间隔件在密封玻璃窗单元中引入的热桥的影响。
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。
测量在规定的条件下进行,以便比较测量值。
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 thermal transmittance of frame and sash components of windows and doors, including mullions and transoms.
The thermal bridging effect of window or door components (handles, hinges, closing devices, etc.) is included.
The test procedure is designed to take into account the whole developed area of the frame or sash surface, but excludes the influence of the thermal bridge introduced through the spacer in sealed glazing units.
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 measurements are performed under defined conditions to facilitate the comparison of measured values.
Information on the design of the calibration transfer standard is given in EN ISO 12567-1.
