Definitions of EN 60335 [1/9]
EN60335-Household and similar electrical appliances Safety —Part 1: General requirements
rated voltage
voltage assigned to the appliance by the manufacturer
rated voltage range
voltage range assigned to the appliance by the manufacturer, expressed by its lower and
upper limits
working voltage
maximum voltage to which the part under consideration is subjected when the appliance is
supplied at its rated voltage and operating under normal operation
NOTE 1 The different positions of controls and switching devices are taken into account.
NOTE 2 Working voltage takes into account resonant voltages.
NOTE 3 When deducing the working voltage, the effect of transient voltages is ignored.
rated power input
power input assigned to the appliance by the manufacturer
rated power input range
power input range assigned to the appliance by the manufacturer, expressed by its lower and
upper limits
rated current
current assigned to the appliance by the manufacturer
NOTE If no current is assigned to the appliance, the rated current is
– for heating appliances, the current calculated from the rated power input and the rated voltage;
– for motor-operated appliances and combined appliances, the current measured when the appliance is supplied at rated voltage and operated under normal operation.
rated frequency
frequency assigned to the appliance by the manufacturer
rated frequency range
frequency range assigned to the appliance by the manufacturer, expressed by its lower and
upper limits
normal operation
conditions under which the appliance is operated in normal use when it is connected to the
supply mains
rated impulse voltage
voltage derived from the rated voltage and the overvoltage category of the appliance,
characterizing the specified withstand capability of its insulation against transient overvoltages
dangerous malfunction
unintended operation of the appliance that may impair safety "
remote operation
control of an appliance by a command that can be initiated out of sight of the appliance using
means such as telecommunications, sound controls or bus systems
NOTE. An infra-red control by itself is not considered one used for remote operation. However, it may be incorporated as part of a system such as a telecommunication, sound control or bus system.
