    摘要: A test apparatus (1) is provided for finding and locating defects in a workpiece (5, 6) The apparatus (1) has at least one heat source (2, 7, 13, 14), at least one sensor apparatus (3, 10, 11, 12) for determining the temperature distribution on at least one surface (8) of the workpiece (5,6), and an evaluation apparatus (4) connected to the sensor apparatus (3, 10, 11, 12) in which apparatus the workpiece (5, 6) and the test apparatus (1) are arranged such that they can move relative to one another in a direction (R) parallel to the surface (8) which has been exposed to the heat. The sensor apparatus (3, 10, 11, 12) extends at least along a line which is transverse with respect to the direction (R) of relative movement downstream of the heat source (2, 7, 13, 14) as seen in the direction (R) of relative movement, in order to measure the temperature distribution along at least this line. A test method for finding and locating a defect by means of a test apparatus of this type is also provided.
