Abstract
Abstract The current EN 50242/EN 60436:2008 tests the performance of electric household dishwashers by using soiled dishes persistently dried in a thermal cabinet. Assuming the conditions of soiling load and persistence of the soiling as representative for consumer behaviour may be challenged. The difficulty in laboratory testing is to simulate usage behaviour under restrictions of limited time and personnel conditions. The task was to verify if the thermal drying of dishes in a thermal cabinet is able to mimic the typical air drying of dishes in consumer households. Experiments were conducted comparing the cleaning performance of a dishwasher load after air drying the soiled dishes in controlled ambient conditions to the cleaning performance of a dishwasher load after a thermal drying process in a thermal cabinet. Results show that thermal drying is able to display dishwashing frequencies for 91.6% of German households.
