Test criteria
The comparative product test evaluates the following technologies in domestic washing machines:
Automatic 2-Phase Dosing System
Quality label on the basis of the comparable product tests using our in-house methods. Various primary and secondary washing effects (removal of stains, degree of whiteness, greying) while using the automatic dosing system and detergent from the manufacturer are compared with industry-standard market products and manual dosing. The accuracy of the automatic dosing system was also tested.
Washing Machine Drum Technology
In this test, we carried out a comparative assessment of domestic washing machines featuring different drum technologies.
We used a selected wash cycle to wash the same load of laundry several times. We then examined how gently the machines treated the fabrics and how many fibres were shed from them.
Fabric care was assessed visually by our trained team of testers. To measure fibre loss, we determined the number of natural and synthetic fibres in samples of the wash water using a special image analysis method.
