Below, we have compiled the common global EMC (Electromagnetic Compatibility) standard systems and main standard lists for you, with a focus on China's national EMC standard system and its primary standards. This content can help you understand the technical specification requirements for EMC in different global markets.

I. Major Global EMC Standard Systems and Standards

Global EMC standards are primarily formulated by international organizations, regional bodies, and national standard institutions. While specific limits and test methods vary across national/regional standard systems, many countries adopt or reference IEC/CISPR international standards.

1. International General Standards

(1) IEC Series — International Electrotechnical Commission

IEC is the core publishing body for global EMC standards. Its standards serve as foundational standards or the basis for adoption in most countries/regions. Common examples include:

IEC 61000 Series — Electromagnetic Compatibility (EMC) Fundamentals, Limits, and Measurement Methods

IEC 61000-1-1: Terminology and Definitions

IEC 61000-2-1: Environmental Standards

IEC 61000-3-2 / IEC 61000-3-3: Harmonic Current Limits and Voltage Fluctuation/Flicker

IEC 61000-4 Series: Immunity and Test Methods (e.g., ESD, Surge, Radiated Immunity, Conducted Immunity)

IEC 61000-6-1 ~ 6-4: Generic Emission/Immunity Standards (Residential, Commercial, Industrial Environments)

(2) CISPR Series — International Special Committee on Radio Interference

The CISPR series, under IEC, is a crucial standard for EMI (Interference) product EMC limits and test methods:

CISPR 11: EMI Limits for Industrial, Scientific, and Medical Equipment

CISPR 14-1 / CISPR 14-2: Household Appliances and Electric Tools

CISPR 15: Lighting Equipment and Similar Products

CISPR 22 / CISPR 32: Information Technology Equipment and Multimedia Equipment

CISPR 24 / CISPR 35: Immunity Guidelines

(3) Other International Standards and References

The following are some international/industry-specific EMC-related standards (typically used for specific industries/scenarios):

ISO 7637 & ISO 11452: Automotive Electromagnetic Compatibility Testing

IEC 60601-1-2: EMC Requirements for Medical Equipment

MIL-STD-461: EMC Requirements for Military Equipment

RTCA/DO-160: EMC Testing for Avionics

2. EMC Standards of Major Economies/Regions

Building upon international foundations, countries/regions establish regulations or implement standards to meet local market access requirements:

| Region/Country | Standard/Regulatory System | Remarks |

| :--- | :--- | :--- |

| European Union (EU) | EMC Directive + EN Series Standards (e.g., EN 55032/EN 61000 Series) | CE Marking Required |

| USA/Canada | FCC Part 15 / ICES Series | Different Limits/Classes |

EMC Standards System in China

China's EMC national standards system is primarily structured under the GB/GB-T numbering system. Some of these standards are mandatory national standards (GB), while others are recommended national standards (GB/T). Many of these standards adopt or are equivalent to IEC/CISPR international standards, with some localized adjustments.

1. Core Generic EMC Standards

| Standard Number | Standard Name / Content | Remarks |

| :--- | :--- | :--- |

| GB 17799.3-2023 | EMC Generic Standard Part 3: Emission Standard for Residential Environments | Corresponds to IEC 61000-6-3; Implemented on 2024-07-01 |

| GB 17799.8-2023 | EMC Generic Standard Part 8: Emission Standard for Commercial/Light Industrial Environments | Corresponds to the general emission requirements of IEC 61000-6-4 |

| GB/T 17799.2-2023 | EMC Generic Standard Part 2: Immunity Standard for Industrial Environments | General requirements for industrial environments |

| GB/T 9254.1-2021 | Emission Requirements for Information Technology Equipment/Multimedia Equipment (Equivalent to CISPR 32) |

| GB/T 9254.2-2021 | Immunity Requirements for Information Technology Equipment |

Among these, GB/T 9254.1-2021 has replaced the old EMC standard and consolidated multiple GB EMC product standards since 2022.

3. EMC Standards for Household Appliances / Industrial / Vehicle Equipment

(This is only a partial list of representative standards; the detailed system is extensive and can be subdivided by product.)*

IV. How to Understand and Apply These Standards

✔ The IEC/CISPR standards constitute the global core technical framework for EMC. Most national/regional EMC standards are developed or equivalently adopted based on these international standards.

✔ Specific application standards for EMC differ across countries/regions. For export trade, corresponding filing or testing must be conducted according to the target market (e.g., EU CE, US FCC/CSA, Korea KC, Japan VCCI, China CCC).

✔ The Chinese GB standard system is currently being updated (e.g., new standards released 2023~2026). Product design requires close attention to announcements from the SAMR/China National Standards Platform.
