The testing medium (31) for standardised ascertainment of the quality of a washing, cleaning and/or drying operation comprises a two- or three-dimensional article in the form of a carrier element (32). Detachable particles (24) are applied to the carrier element in a defined density by physical and chemical actions. The particles have a defined size and defined holding power and consist of plastic.
