This European Standard deals with the safety of microwave ovens for household and similar use, their rated voltage being not more than 250 V. This European Standard also deals with combination microwave ovens, for which Annex AA is applicable. This standard also deals with microwave ovens intended to be used on board ships, for which Annex BB is applicable. As far as is practicable, this European Standard deals with the common hazards presented by appliances that are encountered by all persons in household and similar environments. However, in general, it does not take into account: - children playing with the appliance; - the use of the appliance by very young children; - the use of the appliance by young children without supervision. It is recognized that very vulnerable people may have needs beyond the level addressed in this European Standard.
