Abstract: The method comprises the following steps: bonding at least one chemical, optically luminescent compound (3) onto at least one indicator element (6) for testing the treatments (14), wherein at least one luminescence property of the chemical compound (3) can be changed; assigning at least one indicator element (6) to the object (1); wherein the indicator element (6) and the object (1) are simultaneously subjected to the same conditions of the energy-introducing treatment (14); changing the luminescence property of the chemical compound (3), wherein the level of the change to the luminescence property depends upon the energy-introducing treatment (14); irradiating (13) the chemical compound (3) with electromagnetic radiation directed onto the indicator (6) for excitation of the luminescence during the energy-introducing treatment or following the energy-introducing treatment (14).
