EXECUTIVE SUMMARY
Scope: electrical equipment for measurement, control and laboratory use (测量、控制和实验室用电气设备) — safety of the general product plus its Part 2 sub-categories. The Chinese GB 4793 series is an IDT adoption of an older IEC edition (IEC 61010-1:2001, Ed. 2) while IEC 61010-1 is now Ed. 3 (2010+A1:2016); equivalence is therefore MOD, not IDT, against the current IEC text. Procurement implication: a CB/IEC 61010-1 Ed.3 test report does not automatically satisfy GB 4793.1-2007 — clause-by-clause gap assessment plus CCC/CCCF scope check is mandatory.

⚠️ Part-number ↔ IEC mapping differs between sources (A and B disagree on GB 4793.3/4793.5/4793.6 ↔ IEC 61010-2-0xx pairing). Verify: each GB 4793.x cover page for the cited IEC 61010-2-xxx edition.
STANDARD TIER CLASSIFICATION
| Standard | Tier | Description |
|---|---|---|
| GB 4793.1-2007 | TIER 1 — Product Safety Standard | Defines safety requirements for the equipment |
| IEC 61010-1:2010+A1:2016 | TIER 1 — Product Safety Standard | Defines safety requirements for the equipment |
| GB 4793.2–4793.9 | TIER 1 — Product Safety Standard (Part 2 particulars) | Sub-category product requirements |
| GB/T 18268.1-2010 | TIER 1 — Product Standard (EMC) | EMC requirements, separate domain |
FLAG: No tier mismatch. Both sides are TIER 1 — comparison is valid. EMC (GB/T 18268.1) is a separate compliance domain and must not be conflated with safety.
SCOPE BREAKDOWN
General requirements (通用要求)
Chinese standard: GB 4793.1-2007 — 测量、控制和实验室用电气设备的安全要求 第1部分：通用要求
International equivalent: IEC 61010-1:2010+A1:2016 — ⚠️ GB is IDT to IEC 61010-1:2001 (Ed. 2), one edition behind.
Equivalence: MOD (against current IEC Ed. 3); IDT against IEC Ed. 2
Standard tier match: Both TIER 1 — valid comparison
| Parameter | Chinese Standard Value (Clause) | International Value (Clause) | Deviation | Mutual Recognition | Procurement Impact |
|---|---|---|---|---|---|
| Edition basis | IEC 61010-1:2001 Ed.2 (GB 4793.1-2007 foreword) | Ed.3 2010+A1:2016 | One edition gap | 附加测试后互认 (Mutual recognition after additional testing) | HIGH |
| Clearance/creepage | Per GB 4793.1-2007 tables [Verify: GB 4793.1-2007 §6.7] | Ed.3 revised tables (IEC 61010-1:2010 §6.7) | Different table values | 附加测试后互认 (Mutual recognition after additional testing) | HIGH |
| Dielectric strength test voltage | [Verify: GB 4793.1-2007 §6.8] | [Verify: IEC 61010-1:2010 §6.8] | Verify | 附加测试后互认 (Mutual recognition after additional testing) | HIGH |

| Protection against hazards | General clauses present | Ed.3 adds/revises requirements | Structural | 附加测试后互认 (Mutual recognition after additional testing) | MEDIUM |
Part 2 sub-categories (第2部分特殊要求)
Each GB 4793.x is IDT to the corresponding IEC 61010-2-0xx of the same era; the same one-edition lag applies. Sub-categories covered: current sensors (GB 4793.2), mixing/stirring (GB 4793.3), centrifuges (GB 4793.5), heating equipment (GB 4793.6), analysers (GB 4793.7), IVD equipment (GB 4793.9).
Equivalence: MOD vs current IEC Part 2 editions.
Standard tier match: Both TIER 1 — valid.
| Parameter | Chinese Standard Value (Clause) | International Value (Clause) | Deviation | Mutual Recognition | Procurement Impact |
|---|---|---|---|---|---|
| Part 2 edition basis | IEC 61010-2-0xx (2001-era) | Current IEC 61010-2-0xx | One edition gap | 附加测试后互认 (Mutual recognition after additional testing) | HIGH |
| Sub-category coverage | GB 4793.2/.3/.5/.6/.7/.9 | Full IEC 61010-2-xxx range | GB set incomplete vs IEC | 不可互认 (Not mutually recognised) for uncovered sub-types | HIGH |
KEY DIFFERENCES SUMMARY
- Edition gap — GB 4793.1-2007 = IEC 61010-1:2001 (Ed.2); IEC current = Ed.3 (2010+A1:2016). Deviation: one full edition. 附加测试后互认 (Mutual recognition after additional testing). Impact: HIGH.
- Clearance/creepage tables — revised in IEC Ed.3; GB retains Ed.2 values. 附加测试后互认. Impact: HIGH.
- Dielectric test voltages — must be re-verified against both texts. 附加测试后互认. Impact: HIGH.
- Part 2 coverage gap — GB 4793 series does not mirror every IEC 61010-2-xxx. 不可互认 (Not mutually recognised) for uncovered sub-types. Impact: HIGH.
- EMC is separate — GB/T 18268.1-2010 governs EMC; not covered by GB 4793.1. Impact: MEDIUM.
REGULATORY LINKAGE TABLE (法规联动)
| Compliance Scenario | Chinese Regulatory Basis | International Regulatory Basis |
|---|---|---|
| Mandatory product certification | CCC / CCCF where in scope [Verify: CNCA CCC catalogue for 测量控制实验室设备] | CB Scheme (IECEE), UL Listing, CE (LVD 2014/35/EU), UKCA |
| Engineering acceptance inspection | N/A for product standard comparison | N/A — product safety standard, not installation code |
| Import/export compliance | CCIB commodity inspection; CCC mark where applicable | Destination-country customs + safety mark |
| Designer/engineer obligation | N/A for product standard comparison | Local electrical safety regulation / LVD |
AUDIT FLAG RESOLUTION
- ✅ RESOLVED: GB 4793.1-2007 status = CURRENT (现行) per official authority. No supersession note added.
- ✅ RESOLVED: GB 4793.2-2008 status = CURRENT (现行). No supersession note added.
- 🔴 CRITICAL CORRECTION: Answer A speculated "GB 4793.1-2024 may exist" — false. Official status is CURRENT 2007 edition. Removed.
- ⚠️ UNRESOLVED: A vs B disagree on GB 4793.x ↔ IEC 61010-2-0xx pairing. Verify each GB 4793.x cover page.
- ⚠️ UNRESOLVED: IEC 61010-1 amendment status beyond A1:2016 (possible AMD2) — verify against IEC webstore.
PROCUREMENT VERDICT
- Obtain the CB/IEC 61010-1 Ed.3 test report AND a GB 4793.1-2007 gap assessment (clearance, creepage, dielectric).
- Confirm the exact GB 4793.x Part 2 applicable to your sub-category; do not assume IEC Part 2 equivalence.
- Verify CCC/CCCF scope applicability before shipment.
- Commission GB/T 18268.1-2010 EMC testing separately.
- Require supplier declaration of the IEC edition their design was tested to.
- Re-test to GB clauses where Ed.2 vs Ed.3 values diverge.
