EN 61000-6-3
EN IEC 61000-6-3 is the European generic electromagnetic compatibility (EMC) emission standard for equipment intended for use in residential environments. It is based on IEC 61000-6-3 and is used when no relevant dedicated product or product-family EMC emission standard has been published.
The standard defines emission requirements intended to provide an adequate level of protection for radio reception in residential locations. If there is uncertainty about the intended environment, the residential emission requirements apply. Commercial and light-industrial environments should not be presented as the primary scope of the current edition.
Scope and Application
The standard may apply to electrical and electronic equipment that:
is intended for use in residential locations;
has no applicable dedicated product or product-family emission standard; and
can produce conducted or radiated disturbances that may affect radio reception.
Product-specific standards take precedence where they apply. Equipment categories such as multimedia equipment, household appliances or lighting may therefore fall under their own emission standards rather than EN IEC 61000-6-3.
Key Technical Requirements
| Port and range | Limit and detector |
|---|---|
| AC mains, 0.15–0.5 MHz | 66–56 dBµV QP 56–46 dBµV average Decreasing logarithmically with frequency |
| AC mains, 0.5–5 MHz | 56 dBµV QP 46 dBµV average |
| AC mains, 5–30 MHz | 60 dBµV QP 50 dBµV average |
| Radiated, 30–230 MHz at 10 m | 30 dBµV/m QP |
| Radiated, 230–1000 MHz at 10 m | 37 dBµV/m QP |
| Radiated, 1–3 GHz at 3 m | 70 dBµV/m peak 50 dBµV/m average |
| Radiated, 3–6 GHz at 3 m | 74 dBµV/m peak 54 dBµV/m average |
| Port / measurement | Frequency range | Limit |
|---|---|---|
| AC mains conducted emissions | 0.15–0.5 MHz | 66–56 dBµV QP; 56–46 dBµV average, decreasing logarithmically |
| AC mains conducted emissions | 0.5–5 MHz | 56 dBµV QP; 46 dBµV average |
| AC mains conducted emissions | 5–30 MHz | 60 dBµV QP; 50 dBµV average |
| Radiated emissions at 10 m | 30–230 MHz | 30 dBµV/m QP |
| Radiated emissions at 10 m | 230–1000 MHz | 37 dBµV/m QP |
| Radiated emissions at 3 m | 1–3 GHz | 70 dBµV/m peak; 50 dBµV/m average |
| Radiated emissions at 3 m | 3–6 GHz | 74 dBµV/m peak; 54 dBµV/m average |
- Applicability above 1 GHz: The required upper measurement frequency depends on the highest frequency generated or used within the equipment.
- Other ports: DC power ports and other wired network or signal ports have separate requirements where applicable; the AC mains limits above must not be transferred to them.
- Measurement distance: Permitted distances depend on the frequency range and test facility and can range from 1 m to 30 m. The limits shown above are tied to the stated distances.
- Methods: Instrumentation and measurement procedures are specified through the applicable CISPR 16 series references.
Typical Test Setup
Conducted emissions: An appropriate artificial network, such as a LISN for the AC mains port, is connected to an EMI receiver.
Radiated emissions: Measurements may use facilities such as an open-area test site, semi-anechoic chamber, fully anechoic room or free-space open-area test site, depending on the frequency range and equipment.
Operating mode: The equipment under test is configured and exercised to represent the modes expected to produce the highest emissions.
Conformity under the EMC Directive
Where it is applicable and its reference is published in the Official Journal of the European Union, EN IEC 61000-6-3 can support a presumption of conformity with the emission-related essential requirements of Article 6 and Annex I of the EMC Directive 2014/30/EU. The presumption is limited to the requirements covered by the standard.
Test reports form part of the technical documentation. The EU Declaration of Conformity identifies the harmonized standards or other technical specifications actually applied; it does not need to list each individual test report.
Lifecycle Relevance
Development: Pre-compliance measurements can identify emission risks before formal testing.
Conformity assessment: The applicable product configuration and ports are tested and documented.
Changes: Hardware, software, enclosure, cable or power-supply changes should be assessed for their effect on emissions.
Standards monitoring: The applicable edition and its Official Journal status should be checked throughout the product lifecycle.
