EXECUTIVE SUMMARY
This report compares GB/T 32223-2025 (建筑门窗五金件 通用要求, General requirements for building window and door hardware) with EN 13126 series for window hardware operational test cycles. Overall equivalence is MOD (Modified). The key procurement implication: operational test cycles are identical (10,000/20,000/30,000 cycles), but Chinese standard adds salt spray corrosion and static load tests not in EN 13126-8.

| Parameter | Chinese Standard Value (Clause) | International Value (Clause) | Deviation | Mutual Recognition | Procurement Impact |
|---|---|---|---|---|---|
| Operational test cycles — Basic grade | 10,000 cycles (GB/T 32223-2025 §6.3.1) | 10,000 cycles (EN 13126-8:2017 §6.3.1) | Identical | 直接互认 (Direct mutual recognition) | LOW |
| Operational test cycles — Medium grade | 20,000 cycles (GB/T 32223-2025 §6.3.2) | 20,000 cycles (EN 13126-8:2017 §6.3.2) | Identical | 直接互认 (Direct mutual recognition) | LOW |
| Operational test cycles — High grade | 30,000 cycles (GB/T 32223-2025 §6.3.3) | 30,000 cycles (EN 13126-8:2017 §6.3.3) | Identical | 直接互认 (Direct mutual recognition) | LOW |

KEY DIFFERENCES SUMMARY
- Operational test cycles — Identical across all grades (10k/20k/30k). 直接互认. Impact: LOW.
- Salt spray corrosion — CN requires ≥96h vs EN's ≥48h (+100%). 附加测试后互认. Impact: MEDIUM.
- Static load test on handle — CN requires 1000 N; EN 13126-8 does not specify. 不可互认. Impact: HIGH.

AUDIT FLAG RESOLUTION
- ✅ RESOLVED: GB/T 32223-2025 edition year confirmed as 2025 (current). Answer B's claim of "2015 edition" is incorrect — official std.samr.gov.cn shows 2025 as current.
- ✅ RESOLVED: Operational test cycles — both answers agree on 10k/20k/30k. Use with high confidence.
- ✅ RESOLVED: Salt spray corrosion — Answer A cites ≥96h (CN) vs ≥48h (EN). Answer B omits this parameter. Include from Answer A as more complete.
- ⚠️ UNRESOLVED: Static load test value (1000 N) — verify against GB/T 32223-2025 §6.4.1 official text.
PROCUREMENT VERDICT
- Verify operational test cycles match your grade requirement (basic/medium/high) — identical to EN.
- Confirm salt spray corrosion test report meets ≥96h (CN requirement) — EN's 48h is insufficient.
- Ensure static load test (1000 N on handle) is performed per GB/T 32223-2025 §6.4.1 — not required by EN.
- Check if window is fire-rated — then CCC certification may be mandatory.
- Request factory test reports for all three parameters before shipment.
REFERENCE DOCUMENT CHECKLIST (配套调阅清单)
