normal operation: conditions under which the appliance is operated in normal use when it is connected to the supply mains. normal operation is the state of working in the way specified in the instruction manual usually. Sometimes it is also the state of working in the way specified in the standard, although this mode of…
If there are ambiguities in our understanding of the standards, or if there are no clear requirements in the standards, or if we are unsure of the strength of the standards’ implementation, at first, we can by checking the following webpage to see if there is a decision that we can refer to for the…
There are 7 rated item from clause 3.1.1 to clause 3.1.8 except for clause 3.1.3, such as rated voltage, rated voltage range, rated power input, rated power input range, rated current, rated frequency, rated frequency range. To summarize the intent of the standard, “rated” represents a set of parameters assigned to the appliance by the…
rated frequency range: frequency range assigned to the appliance by the manufacturer, expressed by its lower and upper limits. The rated frequency in the form of a range, generally 50-60 Hz, but all countries in the world have either 50 Hz or 60 Hz mains frequency, there is no intermediate frequency value, so the definition…
rated frequency: frequency assigned to the appliance by the manufacturer. In generally, the rated frequency is the standard utility frequency of the target market country at the time the product is designed. Since worldwide, there are only two utility frequencies, 50Hz and 60Hz, the value can only be 50Hz or 60Hz, or both 50 and…
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…
rated power input range: power input range assigned to the appliance by the manufacturer, expressed by its lower and upper limits. This definition corresponds to the rated voltage range, which means that the rated power input is labeled with a range of upper and lower limits.Example: A quartz tube room heater with a rated voltage…
rated power input:power input assigned to the appliance by the manufacturerNote 1 to entry: If no power input is assigned to the appliance, the rated power input for heating appliances and combined appliances is the power input measured when the appliance is supplied at rated voltage and operated under normal operation. In general, the manufacturer…
working votlage: maximum voltage to which the part under consideration is subjected when the appliance is supplied at its rated voltage and operating under normal operation, with controls and switching devices positioned so as to maximize the value NOTE 1 working voltage takes into account resonant voltages. NOTE 2 When deducing the working voltage, the…
