A Brief Course on Electromagnetic Compatibility (2) Electromagnetic Compatibility Standards

In order to ensure the electromagnetic compatibility working characteristics that the equipment and its various units must meet, a series of electromagnetic compatibility standards have been formulated by relevant international agencies, governments and military departments of various countries, as well as other relevant organizations. The standard stipulates and limits the electromagnetic disturbance emission and electromagnetic immunity of equipment. The electromagnetic compatibility standard is a guiding document for electromagnetic compatibility design and the basis for electromagnetic compatibility testing, because the test items, test methods and limit values ​​are all given by the standard.

The electromagnetic compatibility standard is a guiding document for electromagnetic compatibility design and the basis for electromagnetic compatibility testing, because the test items, test methods and limit values ​​are all given by the standard.

1. The formulation of electromagnetic compatibility standards

Electromagnetic compatibility standards are mainly formulated by standardization organizations. The main international standardization organizations that formulate electromagnetic compatibility are shown in the following table.

A Brief Course on Electromagnetic Compatibility (2) Electromagnetic Compatibility Standards

IEC (International Electrotechnical Commission) has two equal organizations to develop EMC standards, namely CISPR (International Radio Interference Special Committee) and TC77 (77th Technical Committee).

CENELEC (European Committee for Electrotechnical Standardization) is authorized by the European Commission to formulate European standards EN (European Norm).
The FCC (Federal Communications Commission) mainly formulates civil standards, and the standards for electromagnetic compatibility are mainly included in FCC Part15 and FCC Part18.
MIL-STD is a US military standard.
Germany’s VDE (Association of Electrical Engineers) is one of the first organizations in the world to establish electromagnetic compatibility standards.
Japan’s VCCI (Voluntary Control Council for Interference) is a private organization whose standards are aligned with CISPR and IEC standards.
my country’s EMC standardization work is carried out under the leadership of the State Bureau of Technical Supervision. Domestic standards start with GB and GB/T. Since my country issued the first EMC standard (GB3907-1983) in 1983, 47 relevant national standards have been issued so far, of which 32 are mandatory and 15 are recommended. Most of my country’s EMC standards are imported from international standards. Its sources include:

Publication of the International Special Committee on Radio Interference. For example GB/T6113, GB14023
International Electrotechnical Commission. For example GB4365, GB/T13926
Partially quoted from US Military Standards. For example GB15540
Partly quoted from the relevant documents of the International Telecommunication Union. For example GB/T15658
Quoted from foreign advanced standards. For example GB6833
According to the standards formulated by my country’s own scientific research achievements, such as GB/T15708 For the needs of world trade, many EMC standards in my country have adopted CISPR and IEC standards. In fact, most countries in the world adopt the standards of CISPR and IEC.

2. Theoretical basis for the formulation of EMC standards

One of the main contents of the EMC standard is to specify the limit values ​​of electromagnetic disturbance and electromagnetic immunity. The formulation of limit values ​​should theoretically meet the principles shown in the following figure:

A Brief Course on Electromagnetic Compatibility (2) Electromagnetic Compatibility Standards

EMI and EMS are opposed to each other. The above figure shows that there should be enough margin (IM) between the EMI limit value of the device and the EMS limit value, that is, the EMI emission of the device should be less than its immunity (EMS) , so that the device has sufficient anti-interference ability. On the other hand, there should be enough margin between the measured values ​​of EMI and EMS of the equipment and the limit value. For example, in the EN300 386 standard, the radiated emission limit (EMI Limit) is 40dBuV/m, while the radiated immunity limit is 130dBuV. It can be seen that the importance of the margin between the EMI and EMS limit values.

3. Classification of electromagnetic compatibility standards

Electromagnetic compatibility standards can be divided into: basic standards, general standards, product standards and special standards.

The basic standard is the basis for formulating other EMC standards. It describes the EMC phenomenon, specifies the test methods, test equipment and arrangement of electromagnetic disturbance emission and immunity, and defines the test level and performance criteria, but does not involve specific The product. For example: IEC61000-XX series standard.

Product standards and special standards are formulated for EMC testing of a certain product series and special products. It often cites the content of the basic standard, and at the same time makes more detailed provisions for the test according to the particularity of the product. For the disturbance emission test, it specifies the disturbance emission limit of the product. For the immunity test, it specifies the test level and performance criteria that the product should reach. like:

CISPR11 EN55011: Emission requirements for ISM engineering and medical equipment
CISPR22 EN55022: Emission requirements for ITE information technology equipment
CISPR24 EN55024: Immunity requirements for ITE information technology equipment
GB6833 Electromagnetic Compatibility Test Specification for Electronic Measuring Instruments

Usually specific product EMC standards are included in a general-purpose standard for a specific product, rather than forming a separate EMC standard. For example: Computer: GB9813-88: General technical conditions for micro digital electronic computers, including electromagnetic compatibility testing items, which are required to be carried out according to GB6833.2 ~ GB6833.6 and GB9254.
The general standard is classified according to the environment in which the product is used. For example, the classification in the European standard is carried out in the following table. The general standard specifies which ports should be tested for emission and immunity of the equipment, including the AC and DC power ports, signal and data line ports, chassis, grounding points, etc. of the equipment, and also specifies the basic standards that can be based on.

Such as: EN50082-1: General Standard for Environmental Immunity in Residential, Commercial and Light Industrial Areas
EN50082-2: General Standard for Environmental Immunity in Industrial Areas
EN50081-1: General Standard for Environmental Emissions in Residential, Commercial and Light Industrial Areas
EN50081-2: Generic Standard for Emissions in Industrial Environments

Automotive electronic products EMC test project

4. The electromagnetic compatibility standard of the product follows the principles

Products follow the principles of the standard in this order:

Special product standard → product standard → general standard

That is, if a product has a special product standard, its EMC performance should meet the requirements of the special product standard; if not, the product standard should be used for the EMC test, and if there is no product standard, the general standard should be used. , and so on.
