IEC/EN 61000-6-3 is intended to address electrical and electronic equipment for use in residential, commercial and light-industrial environments. This generic EMC emissions standard is applicable if no relevant dedicated product or product-family EMC immunity standard exists.

This standard applies to apparatus intended to be directly connected to a low-voltage public mains network or connected to a dedicated DC source which is intended to interface between the apparatus and the low-voltage public mains network. This standard applies also to apparatus which is battery operated or is powered by a non-public, but non-industrial, low voltage power distribution system if this apparatus is intended to be used in the locations described below.

The environments encompassed by this standard are residential, commercial and light industrial locations, both indoor and outdoor. It includes:

  • Residential properties e.g. houses, apartments
  • Retail outlets e.g. shops, supermarkets
  • Business premises e.g. offices, banks
  • Areas of public entertainment e.g. cinemas, public bars, dance halls
  • Outdoor locations e.g. petrol stations, car parks, amusement and sports center
  • Light-industrial locations e.g. workshops, laboratories, service centers.

Require­ments include both conducted and radiated emissions.

Conducted emis­sion require­ments for mains ports and telecom­mu­ni­ca­tion ports must be tested in fre­quency range 0 kHz- 30 MHz

Radi­ated emis­sion require­ments must be tested at the referenced fre­quency rages below:

  • 30MHz-1GHz if inter­nal oscil­la­tor fre­quency is up to 108MHz
  • 30MHz-2GHz if inter­nal oscil­la­tor fre­quency is up to 500MHz
  • 30MHz-5GHz if inter­nal oscil­la­tor fre­quency is up to 1GHz
  • 30MHz-6GHz if inter­nal oscil­la­tor fre­quency is higher than 1GHz

If the inter­nal clock fre­quency is not known the mea­sure­ments shall be car­ried out up to 6GHz.
If the inter­nal oscil­la­tor fre­quency or work­ing fre­quency is up to 9 kHz the mea­sure­ments shall be made up to 230MHz.

Immunity requirements are not covered by this standard, and would be included in IEC/EN 61000-6-1.

Safety considerations are not covered by this standard as well. Equipment used in commercial, residential, or light industrial applications may fall under the requirements of the EU Low Voltage Directive 2014/35/EU or the EU Machinery directive 2006/42/EEC.

Wireless Applications

Electrical and electronic equipment that have wireless capabilities (transmitter-receiver) may have to meet wireless regulations as well as medical device and equipment regulations.  Pre-approved wireless module certification in many cases in not enough to show compliance for devices and equipment for household appliances and similar equipment. D.L.S. can assist in determining the specific requirements needed to meet all U.S., Canada, EU and international regulatory requirements for your equipment. The European Union has established requirements under law for wireless enabled products to show compliance with the Radio Equipment Directive 2014/53/EU, to show compliance with CE marking requirements.
