Standardised testing medium for the quality of a washing, cleaning and/or drying process

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.
