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.
