The author experimented to make the following relation clear about the external wall which is finished with the tile, the kind of tile, the condition of the removement, the environment at taking a thermograph, the wavelength of thermo-camera and the characteristic of the thermographs and the precision to distinguish removed parts. By the experiments using the test walls, the following item became clear. (1) The removement of tiles and the removement of fundamental mortar differ in the temperature response speed to the change of solar radiation. (2) As for the walls without solar radiation, it is possible to apply the thermography method, but it is rather unclear. (3) When the solar radiation lashes to the wall, as dark as the color of tile, it is easier to distinguish the removed part. The distinction precision by LW machine is better than the SW machine, when noise is small. (4) When the solar radiation doesn't lash, the wavelength influence to precision of distinction. On the LW machine, when taking the thermograph luster tile, the precision of distinction declines by the noise. (5) It is necessary about 1.0 ℃ to distinguish the shape of the removed part when the solar radiation lashes, and about 0.5 ℃ when the solar radiation dosen't lash. The removment of tyle can be distinguished with smaller temperature difference than removment of mortar. (6) The SW machine is influenced by the reflection of the sun and the contrast of the sunshine and the shade. The LW machine is influenced by the object such as the sky and the opposite building. (7) The author ordered apply-ability for each measurement wavelength, in the thermography method.
