Description:Gb4343 this section applies to its main function is composed of motor, switch or control device to realize the vessels of the rf transmission and radiation harassment, specially produce or exception of the rf energy for lighting.
these appliances include: household appliances, electric tools, use the adjustment of the semiconductor device controller, motor drive electric medical equipment, electric toys, vending machines, and movie or slide projector.
include within the scope of this section And:
- the individual parts of the above mentioned equipment, such as motor, switch gear, such as power supply or protection relay, if not mentioned in this section, for these individual parts no emission requirements. Are not included in this section are: within the scope of the
- in the standard in other countries clearly put forward the radio frequency range all emission requirements of the equipment.
