Deals with the electromagnetic immunity of appliances and similar apparatus for household and similar purposes that use electricity, as well as electric toys and electric tools, the rated voltage of the apparatus being not more than 250 V for single-phase apparatus to be connected to phase and neutral, and 480 V for other apparatus. It specifies the immunity requirements in relation to continuous and transient, conducted and radiated electromagnetic disturbances, including electrostatic discharges, for the above-mentioned apparatus. Apparatus may incorporate motors, heating elements or their combination, may contain electric or electronic circuitry, and may be powered by the mains, by batteries, or by any other electrical power source. Immunity requirements in the frequency range 0 Hz to 400 GHz are covered.
