Introduction
1. Standard Overview
GB/T 17799.2-2023 "Electromagnetic Compatibility (EMC) General Standard Part 2: Immunity Standard for Industrial Environments" is a standard formulated for the immunity test requirements of electrical and electronic equipment used in industrial sites. This standard replaces the old version GB/T 17799.2-2003, and mainly revises the term definitions, test methods and measurement uncertainty.
2. Comparison of standard frameworks
| Standard version | Main changes | Scope of application |
|---|---|---|
| GB/T 17799.2-2003 | - Adjustment of environmental description- Added long-distance line terms- Deleted the immunity test requirements for functional grounding ports | Equipment immunity test in industrial environments |
| GB/T 17799.2-2023 | - Increased measurement uncertainty requirements- Adjusted the frequency range of RF electromagnetic field radiation immunity test- Modified surge and electrical fast transient pulse group immunity test parameters | Electrical and electronic equipment operating in industrial sites |
3. Recommendations for standard implementation
Key implementation steps:
- Determine the scope of application:Select the appropriate test method according to the type of equipment and the working environment.
- Measurement uncertainty assessment:Carry out measurement error analysis in accordance with IEC 61000-1-6 or related basic standards.
- Performance criterion selection:Select A, B or C criteria according to the equipment function and manufacturer requirements.
4. Explanation of professional terms
Port:
The specific interface where the equipment couples with the external electromagnetic environment, including physical boundaries and signal/control ports.
Long Distance Line:
Lines with a length of more than 30 meters or leading outside the building, mainly used in DC distribution networks.
