适用范围：This standard specifies a method for determining the thermal resistance of doors and windows using a guarded or calibrated hot box. The method is primarily intended for laboratory use.The method does not make allowance for the thermal bridges encountered when the unit is installed in a real wall: it relates exclusively to the coefficient of thermal transmittance for the actual door or window (glazing, casement, frame and necessary fittings). The method does not cover the influence of air flows through the test specimen, i.e. exchange of air between the hot and the cold sides.
