Over deze norm
||Gebruikseigenschappen van huishoudelijke en soortgelijke elektrische toestellen
NEN-EN-IEC 60661 applies to electric coffee makers for household and similar use. It does not apply to appliances designed exclusively for commercial or industrial use. The object of this standard is to state and to define the main performance characteristics, which are of interest to the user and to describe the standard methods for measuring these characteristics. This standard is concerned neither with safety nor performance requirements. Taking into account the degree of accuracy and repeatability, due to variations in time and origin of test materials and ingredients and the influence of the subjective judgement of test operators, the described test methods may be applied more reliably for comparative testing of a number of appliances at approximately the same time, in the same laboratory, by the same operator and with the same utensils, rather than for testing single appliances in different laboratories.
