1 Scope
This European Standard applies to electric dishwashers for household use that are supplied
with hot and/or cold water.
The object is to state and define the principal performance characteristics of electric
dishwashers for household use and to describe the standard methods of measuring these
characteristics.
This standard is concerned neither with safety nor with performance requirements.
