This International Standard deals with the safety of electric warming plates, warming trays
and similar appliances intended to keep food or vessels warm, for household and similar
purposes, their rated voltage being not more than 250 V.
Appliances intended for normal household and similar use and that may also be used by
laymen in shops, in light industry and on farms are within the scope of this standard.
However, if the appliance is intended to be used professionally to keep vessels warm or to
process food for commercial consumption, the appliance is not considered to be for
household and similar use only.
