IEC Foreword
1) The International Electrotechnical Commission (IFC) is a worldwide standardization organization composed of the National Electrotechnical Committees (IEC National Committees) of all participating countries. Its purpose is to promote international cooperation on various standardization issues in the field of electrical and electronic engineering. To this end, in addition to carrying out other activities, it also publishes various international standards and entrusts technical committees to formulate standards. IEC National Committees can participate in the formulation of the standards as long as they are interested in them. Other international organizations, governmental and non-governmental organizations that have established relations with the IEC may also participate in this work. The IEC and the International Organization for Standardization (ISO) cooperate closely under the terms of mutual agreement. 2) Since each "· technical committee represents all the national committees concerned, the formal resolutions or agreements of the IEC on technical issues express the international consensus on the issues involved as far as possible. 3) These resolutions or agreements are published in the form of standards, technical reports or guidelines and recommended for international use, and are accepted by the national committees in this sense.
4) In order to promote international consistency, the national committees of the IEC should convert IEC international standards into national or regional standards as far as possible and to the greatest extent possible. Any differences between IEC standards and corresponding national or regional standards should be clearly pointed out in the national or regional standards.
5) It should be noted that some parts of this international standard may involve patent protection. However, the IEC is not responsible for identifying any or all such patent rights.
6) The IEC has not established procedures for indicating any recognition mark. If a device claims that it conforms to an IEC standard, the IEC shall not be responsible for it. | |tt||This standard has been prepared by the International Special Committee on Radio Interference (CISPR). This standard is based on the document EN50081-2:1993 prepared by Technical Committee 110 (TC110, EMC) of the European Committee for Electrotechnical Standardization (CENEI.EC).

The emission requirements specified in this standard apply to electrical and electronic equipment used in industrial environments as described in Chapter 5 and for which no dedicated product or product class emission standards have yet been established.
This standard does not apply to equipment that uses radiated electromagnetic energy for radio communications. The frequency range applicable to this standard is 0Hz to 400GHz. The fault state of the equipment is not considered. When there are dedicated product or product class emission standards, they take precedence over this standard in all respects. The environment described in this standard includes indoor and outdoor environments in industrial locations. This standard does not consider equipment connected to the public power grid, but only considers equipment connected to the power grid supplied by high-voltage or medium-voltage transformers, which only supply power to manufacturing plants or similar facilities. This standard applies to equipment that works in industrial locations or near industrial power facilities. Note: For guidance on selecting the scope of application of EMC general standards, refer to the European Committee for Electrotechnical Standardization (CENEI.EC) report R110-002: 1993 General Standard Guide.
2 Referenced Standards
The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All standards will be revised, and parties using this standard should explore the possibility of using the latest versions of the following standards. GB4343-1995 Household and similar electric and electric heating appliances, electric tools and similar electrical appliances - Measurement methods and allowable values of radio disturbance characteristics (evCISPR14:1993) GB/T4365--1995 Electromagnetic compatibility terminology (idtIEC60050(161):1990) GB4824--2001 Industrial, scientific and medical (ISM) radio frequency equipment - Measurement methods and limits of electromagnetic disturbance characteristics (idt CISPR11:1997)

The purpose of this standard is to specify limits and methods of measurement for electromagnetic emissions of equipment defined within the scope of application, the electromagnetic emissions of which may interfere with other equipment.
These emission limits represent basic electromagnetic compatibility requirements and are selected to ensure that the disturbance levels produced by equipment operating normally in industrial locations will not prevent the normal operation of other equipment. This standard specifies test requirements for each port considered. Approved by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China on November 5, 2001, implemented on November 5, 2003
GB17799.4-2001
When the equipment is used within 30m of the receiving antenna of radio and television receivers, the limits of this standard may not be sufficient to protect them from interference. 2 In special cases, such as when highly sensitive equipment is used nearby, additional mitigation measures may be required to further reduce the electromagnetic emissions to below the specified limits.
4 Definitions
The following terms apply only to this standard:
Port
The specific interface between the equipment and the external electromagnetic environment (see Figure 1). Enclosure port
The physical boundary of the equipment through which electromagnetic fields can radiate or invade. External port
AC power port
DC power port
5 Industrial location
Figure 1 Port example
D.Industrial environments are characterized by one or more of the following conditions: the presence of industrial, scientific and medical (ISM) equipment; frequent switching on and off of large inductive or capacitive loads; "... high currents accompanied by strong magnetic fields.
These are the main components of the industrial electromagnetic environment and are used to distinguish other environments. Measurement conditions
Ground port
Signal port
Process measurement and control port
Measurements should be carried out under normal conditions of use and within the specified frequency band, and under working conditions that can produce maximum emissions. The layout and working conditions of the equipment under test should be changed in accordance with the requirements of the basic standard, and efforts should be made to maximize the emission of the equipment under test. If the equipment under test is part of a system, or is connected to auxiliary equipment, the equipment under test should be configured with a minimum of auxiliary equipment during measurement so that the ports can be used in accordance with regulations similar to those described in GB9254. The layout and working conditions of the equipment under test during measurement should be correctly recorded in the inspection report. If the equipment has many similar ports or some ports have many similar connectors, a sufficient number of ports and connectors should be selected to simulate the actual working conditions to ensure that all different types of terminals are covered. Unless otherwise specified in the basic standard, measurements should be made at rated voltage under the working conditions specified for the equipment. 7 Product documents
7.1 Product documents to be provided
Unless the equipment complies with GB17799.3, a written warning should be provided indicating that the equipment is not suitable for residential, commercial and light industrial environments.

In this case, the reasons for not measuring shall be recorded in the inspection report.
9 Emission limitswwW.bzxz.Net
The emission limits of the equipment involved in this standard are given one by one on a port by port basis. The measurement of each type of disturbance shall be carried out under fully defined and reproducible conditions. The description of the measurement methods and measurement arrangements refers to the basic standards in Table 1 and Table A1.
This standard does not repeat the content of the basic standards. Only the modified or supplementary information required for practical application is given here. Note: The word "basic standard" is used because there is a lack of more appropriate words. The referenced standards (GB4824.GB4343, GB9254, GB17625.1 and GB17625.2) are only (EMC) individual product standards. The reference to "basic standards" is limited to those parts that describe the measurement, test methods and test arrangements of the standard.
