Abstract: A test medium and the use of a corresponding test material are provided for detecting the mechanical load in different assemblies, such as, for example, washing, cleaning and drying machines. A substrate is used, which under mechanical stress loses part of its volume, its weight, or its area, the loss then related to the treatment or processing in the assemblies. The test medium is preferably formed by a fabric composite.

Abstract: A testing medium to which corresponding particles are applied in a defined density. In washing machines, the particles are detached from the testing medium by the mechanical stressing of the testing medium inside the drum, by tumbling, bending or stretching. The physical and/or chemical treatment of the testing medium inside a dishwasher, under various water jets, causes the particles to be detached from the testing medium. The number of particles remaining on the testing medium after the cleaning, washing and/or drying process is a value related to the stressing of the testing medium, and hence to the quality of cleaning and the physical and/or chemical activity of the aggregate during the process. The testing medium can be used in any aggregate which carries out at least one of these processes. Washing machines and dishwashers thus represent only an example.

Abstract: The invention relates to a test means and to the use of a corresponding test material for detecting the mechanical load in different assemblies, such as, for example, washing, cleaning and drying machines. The basic idea of the invention is to use a substrate which, under mechanical stress, loses part of its volume, of its weight and/or of its area and is then put in relation to the treatment or processing in the assemblies. A test means consisting of a fabric composite is preferably proposed.
