A device for assessing a quality class of an object to be tested includes a unit for detecting a test signal from the object to be tested. Furthermore, the device for assessing includes a unit for providing a stochastic Markov model including states and transitions between states on the basis of reference measurements of objects of known quality classes, and a unit for evaluating the test signal using the stochastic Markov model. In addition, the device for assessing includes a unit for associating the object to be tested with a quality class based on the evaluation of the test signal. Such a device has the advantage to be able to perform a more precise association of an object to be tested with a quality class as compared to prior art.
