A method for testing a valve being driven by an electromagnet having a electromagnet armature, includes determining a value of current in the electromagnet as a response current, at an instant when motion of the electromagnet armature of the valve begins during a switching action of the valve. A force acting through the electromagnet upon the electromagnet armature is determined from the determined response current, at the instant when motion of the electromagnet armature begins, by means of a calibration function, as a response force and as a standard for the condition of the valve. An apparatus for testing a valve being driven by an electromagnetic having a electromagnet armature and an electrical circuit, includes a current meter in the electrical circuit of the electromagnet. A computer is connected to the current meter. A memory for a calibration function is connected to the computer for indicating a dependency of a force acting upon the electromagnet armature on a current in the electrical circuit of the electromagnet.
