EXECUTIVE SUMMARY
Scope: EMC generic immunity standard for industrial environments — IEC 61000-6-2 vs Chinese adoption GB/T 17799.2. Landscape: GB/T 17799.2-2023 is IDT with IEC 61000-6-2:2016 (Ed. 3.0); older GB/T 17799.2-2003 tracked Ed. 1 (1999) and is superseded. Key implication: immunity test levels are directly mutually recognised, but the buyer must confirm the equipment is tested to the 2016 Ed. 3 levels (10 V/m, 1.4–6 GHz at 3 V/m), not the legacy 2003 levels.

SCOPE BREAKDOWN
Generic immunity — industrial environments
Chinese standard: GB/T 17799.2-2023: 电磁兼容 通用标准 第2部分：工业环境中的抗扰度标准 (EMC — Generic standards — Part 2: Immunity standard for industrial environments)
International equivalent: IEC 61000-6-2:2016 (Edition 3.0) — ⚠️ Ed. 3.0 supersedes Ed. 2.0 (2005); Ed. 1 (1999) tracked by GB/T 17799.2-2003
Equivalence: IDT
Standard tier match: Both TIER 1 — valid comparison

⚠️ Legacy edition risk: GB/T 17799.2-2003 (Ed. 1) had lower/no 1.4–6 GHz requirement and different pulse-magnetic-field treatment. Confirm the test report cites 2023, not 2003.
KEY DIFFERENCES SUMMARY
- Edition alignment — GB/T 17799.2-2023 = IEC 61000-6-2:2016 (Ed. 3). Older 2003 edition tracked Ed. 1. Deviation: edition gap, not value gap. 直接互认 (Direct mutual recognition) if same edition. Impact: HIGH (wrong edition = invalid test report).
- 1.4–6 GHz radiated RF — Ed. 3 adds 3 V/m above 1 GHz; Ed. 1 lacked it. 直接互认 (Direct mutual recognition) at Ed. 3. Impact: MEDIUM.
- Pulse magnetic field (IEC 61000-4-9 / GB/T 17626.9-2025) — treatment changed between editions. 附加测试后互认 (Mutual recognition after additional testing). Impact: MEDIUM.
- Test-method tier — IEC 61000-4-x vs GB/T 17626.x are IDT pairs; no value deviation. 直接互认 (Direct mutual recognition). Impact: LOW.
REGULATORY LINKAGE TABLE (法规联动)
| Compliance Scenario | Chinese Regulatory Basis | International Regulatory Basis |
|---|---|---|
| Mandatory product certification | CCC (only for products on CCC catalogue; EMC generic standard itself is not CCC-triggering) | CE marking (EMC Directive 2014/30/EU), UKCA |
| Engineering acceptance inspection | N/A for product standard comparison | N/A |
| Import/export compliance | CCIB / commodity inspection where applicable | Destination-country customs + EMC declaration |
| Designer/engineer obligation | N/A for product standard comparison | EU EMC Directive; local building/EMC regulation |
AUDIT FLAG RESOLUTION
- ✅ RESOLVED: GB/T 17799.2-2023 status = CURRENT (现行) per official authority. No supersession note added.
- ✅ RESOLVED: GB/T 17626.9-2025 status = CURRENT (现行). No supersession note added.
