IEC Foreword
1) The International Electrotechnical Commission (IEC) is a worldwide standardization organization composed of the National Electrotechnical Commissions (IEC National Committees) of all participating countries. Its purpose is to promote international consensus on all issues related to standardization in the field of electrical and electronic technology. To this end, in addition to carrying out other activities, it also publishes international standards and entrusts technical committees to formulate standards. Any IEC National Committee interested in the project can participate. International organizations, governmental and non-governmental organizations that have liaison with the IEC can also participate in this work. IEC and the International Organization for Standardization (ISO) work closely together under conditions agreed upon between the two organizations. 2) Since all countries interested in the development of the project are represented in the various technical committees, the formal decisions or agreements made by the IEC on the relevant technical content are as close as possible to international consensus. 3) The resulting documents may be published in the form of standards, technical reports or guidelines, and are recommended for international use and accepted by the National Committees in this sense.
4) In order to promote international consensus, the IEC National Committees should convert IEC International Standards into their national and regional standards to the greatest extent possible. Any differences between the corresponding national or regional standards and IEC International Standards should be clearly stated in the standards.
5) IEC does not take a position on disputes over conformity to the standard, nor does it assume any responsibility for any equipment that claims to conform to a certain standard. 6) It should be noted that some parts of this international standard may involve patent rights. IEC does not assume the responsibility for identifying any or all such patent rights.
This standard was prepared by the International Special Committee on Radio Interference (CISPR). This standard is based on EN50081-1:1992, which was prepared by Technical Committee 110 (Electromagnetic Compatibility) of the European Committee for Electrotechnical Standardization (CENELEC). The following documents have been submitted to the National Committees for voting according to the fast track procedure. Final Draft International Standard

Emission standard for residential, commercial and light-industrial environmentsElectromagnetic compatibility---Generic standardsEmission standard for residential, commercial and light-industrial environmentsGB 17799.3—-2001
idtCISPR/IEC61000-6-3:1996
This standard applies to electrical and electronic equipment used in residential, commercial and light-industrial environments as described in Chapter 5 and for which no dedicated product or product class emission standard exists. This standard does not apply to equipment that generates radiated electromagnetic energy for radio communications. This standard applies to the frequency range of 0 Hz to 400 GHz. In the case of a relevant product or product class EMC emission standard, the product standard or product class standard shall take precedence over this standard in all respects.
The emission requirements specified in this standard ensure that the disturbance level generated by equipment that operates normally in residential, commercial and light industrial environments will not prevent other equipment from operating in the intended manner, but the fault state of the equipment is not considered. The equipment in the environment described in this standard is equipment directly connected to the low-voltage public power grid or equipment connected to the low-voltage public power grid through a dedicated DC power supply. Equipment intended to be connected to an industrial power grid or a dedicated power grid must adopt other general standards. 2 Referenced standards
The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard was published, the versions shown were valid. All standards will be revised. Parties using this standard should explore the possibility of using the latest versions of the following standards: GB4343-1995 Measurement methods and allowable values of radio interference characteristics of household and similar electric and heating appliances, electric tools and similar electrical appliances (eqvCISPR14: 1993) GB/T4365--1995 Electromagnetic compatibility terminology (idtIEC60050 (161): 1990) GB9254-1998 Limits and measurement methods of radio interference of information technology equipment (idtCISPR22: 1997\) GB17625.1-1998 Limits of harmonic currents emitted by low-voltage electrical and electronic equipment (equipment input current per phase <16A) (eqvIEC 61000-3-2:1995)
GB17625.2—1999 Electromagnetic compatibility limits Limits of voltage fluctuations and flickers in low voltage power supply systems for equipment with rated current not exceeding 16A (idtIEC61000-3-3:1994) 3 Purpose
The purpose of this standard is to specify limits and measurement methods for electromagnetic emissions of equipment described within the scope of application, which may interfere with equipment such as radio receivers.
Adoption instructions:
1) The international standard has been updated. The original version is CISPR22:1993. Approved by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China on November 5, 2001 194
2003-11-05 implementation
GB17799.3—2001
These emission limits indicate the basic electromagnetic compatibility requirements. This standard specifies test requirements for each port considered. NOTE
When the equipment covered by this standard is used within 10m of the receiving antenna, the limits of this standard may not be sufficient to protect radio and television reception from interference.
2In some special cases, such as when very sensitive equipment is used nearby, additional mitigation measures may be necessary to further reduce electromagnetic emissions to below a specific level.
4Definitions
In addition to the definitions in the referenced standards, this standard also adopts the following definitions: 4.1 Port port
The specific interface between the specified equipment and the external electromagnetic environment (see Figure 1). AC power port
DC power port
4.2 Enclosure port
External port
Ground port
Equipment under test
Signal/control port
Example of port in Figure 1
The physical boundary of the equipment through which electromagnetic fields can radiate or penetrate. 5 Location description
The environment covered by this standard is the indoor and outdoor environment of residential, commercial and light industrial locations. The following list of locations (although not comprehensive) provides some description of the environment, they include: 1) residential places, such as: houses, apartments, etc.; 2) retail outlets, such as: shops, supermarkets, etc.; 3) business buildings, such as: office buildings, banks, etc., 4) public entertainment areas, such as: cinemas, bars, dance halls, etc.; 5) outdoor places, such as: gas stations, parking lots, playgrounds and sports centers, etc.; 6) light industrial places, such as: workshops, laboratories, maintenance centers, etc. All places that directly obtain low-voltage power supply through the public power grid belong to residential, commercial and light industrial environments. 6 Measurement conditions
Measurements should be carried out within the specified frequency range. The operation of the equipment under test should comply with normal use and be in a working state that produces maximum emission.
Change the layout of the equipment under test to find the maximum emission level. If the equipment under test is part of a system or can be connected to auxiliary equipment, the equipment under test needs to be connected to the minimum configuration of auxiliary equipment during the test so that the port is in an operating state in accordance with the provisions of GB9254. The test configuration and working state during the measurement should be accurately recorded in the test report. If the equipment is equipped with many terminal interfaces, a sufficient number of terminal devices should be selected to simulate the actual working state and ensure that all different types of interfaces are included.
Tests should be carried out at the rated power supply voltage within the specified working environment range of the equipment, unless otherwise specified in the basic standard. 7 Purchaser/User Documents
