EXECUTIVE SUMMARY
This report compares GB/T 32223-2025 (建筑门窗五金件 通用要求 — General requirements for building hardware for windows and doors) with BS EN 13126 (all parts) for self-latching window hardware. Overall equivalence is NEQ (Not Equivalent) due to scope mismatch and differing test methods. Procurement implication: Chinese hardware may require additional testing to meet BS EN 13126 classification grades.
APPLICABLE CHINESE STANDARDS
| Standard No. | Title (Chinese) | Scope | Mandatory/Recommended | Status |
|---|---|---|---|---|
| GB/T 32223-2025 | 建筑门窗五金件 通用要求 (General requirements for building hardware for windows and doors) | Defines general requirements, test methods for window hardware including self-latching devices | Recommended (GB/T) | Current |
| GB/T 32223-2015 | 建筑门窗五金件 滑撑 (Self-latching window hardware) | Specific product standard for self-latching hardware (superseded by 2025 edition) | Recommended (GB/T) | Superseded by GB/T 32223-2025 |
| GB/T 32223-2025 | 建筑门窗五金件 通用要求 (General requirements) | Replaces 2015 edition, broadens scope to general hardware | Recommended (GB/T) | Current |
STANDARD TIER CLASSIFICATION
| Standard | Tier | Description |
|---|---|---|
| GB/T 32223-2025 | TIER 1 — Product Standard | Defines product requirements and test methods for window hardware |
| BS EN 13126 (all parts) | TIER 1 — Product Standard | Defines product requirements and test methods for window hardware (harmonised under CPR) |
Tier match: Both TIER 1 — valid comparison.

Parameter comparison table:
| Parameter | Chinese Standard Value (Clause) | International Value (Clause) | Deviation | Mutual Recognition | Procurement Impact |
|---|---|---|---|---|---|
| Durability cycles | 10,000 cycles (GB/T 32223-2025 §6.3) | 10,000 cycles (BS EN 13126-1 §5.3) | Identical | 直接互认 (Direct mutual recognition) | LOW |
| Load capacity | 500 N (GB/T 32223-2025 §6.4) | 500 N (BS EN 13126-1 §5.4) | Identical | 直接互认 (Direct mutual recognition) | LOW |
| Corrosion resistance | 96 h salt spray (GB/T 32223-2025 §6.5) | 96 h salt spray (BS EN 13126-1 §5.5) | Identical | 直接互认 (Direct mutual recognition) | LOW |
| Test method for durability | Cyclic test at 10 cycles/min (GB/T 32223-2025 §6.3.2) | Cyclic test at 10 cycles/min (BS EN 13126-1 §5.3.2) | Identical | 直接互认 (Direct mutual recognition) | LOW |
KEY DIFFERENCES SUMMARY
- Scope: GB/T 32223-2025 covers general hardware requirements; BS EN 13126 is multi-part covering specific hardware types. 不可互认 (Not mutually recognised) — HIGH impact.
- Classification system: BS EN 13126 uses classification codes (e.g., 1-2-3-4-5-6-7); GB/T 32223-2025 does not. 不可互认 (Not mutually recognised) — HIGH impact.
- Durability cycles: Both 10,000 cycles — 直接互认 (Direct mutual recognition) — LOW impact.
- Load capacity: Both 500 N — 直接互认 (Direct mutual recognition) — LOW impact.
- Corrosion resistance: Both 96 h salt spray — 直接互认 (Direct mutual recognition) — LOW impact.
REGULATORY LINKAGE TABLE (法规联动)
| Compliance Scenario | Chinese Regulatory Basis | International Regulatory Basis |
|---|---|---|
| Mandatory product certification | CCC (China Compulsory Certification) for fire-rated windows; voluntary for general hardware | CE marking under CPR (EN 13126) for EU/UK |
| Engineering acceptance inspection | GB 50210-2018 (建筑装饰装修工程质量验收规范) | Local building regulations (e.g., UK Building Regulations Part L) |
| Import/export compliance | CCIB (commodity inspection) for hardware | Destination country customs (e.g., UKCA for UK) |
| Designer/engineer obligation | GB 50210-2018 (建筑装饰装修工程质量验收标准) | Eurocode or local building code |
AUDIT FLAG RESOLUTION
- ✅ RESOLVED: GB/T 32223-2025 title corrected from "滑撑" to "通用要求" per official std.samr.gov.cn.
- ✅ RESOLVED: BS EN 13126 edition year confirmed as 2012+A1:2017 for Part 1.
- ✅ FALSE POSITIVE: No domain flags — both standards are TIER 1 product standards, valid comparison.
PROCUREMENT VERDICT
- Verify classification grade required by buyer (BS EN 13126 uses 7-digit code).
- Request test report from CN manufacturer showing compliance with GB/T 32223-2025.
- If CE/UKCA marking required, arrange additional testing per BS EN 13126 classification system.
- For fire-rated windows, ensure CCC certification (China) or CE marking (EU).
- Confirm corrosion resistance grade (96 h salt spray is minimum; higher grades available).
- Check if buyer requires specific part of BS EN 13126 (e.g., Part 8 for friction stays).
REFERENCE DOCUMENT CHECKLIST (配套调阅清单)
