EXECUTIVE SUMMARY
BS EN 50288-7 covers 仪表和控制电缆 (Instrumentation and control cables) — a niche industrial signal-transmission category (4–20 mA, thermocouple extension, fieldbus). No direct GB product standard exists; China regulates via GB/T 9330-2020 (control cables) and JB/T 13486-2018 (instrumentation cables), plus design codes. The single most important implication: no 直接互认 (Direct mutual recognition) is possible — Chinese procurement must be re-specified against GB/T 9330-2020/JB/T 13486-2018, not EN 50288-7.
APPLICABLE CHINESE STANDARDS
| Standard No. | Title (Chinese) | Scope | Mandatory/Recommended | Status |

STANDARD TIER CLASSIFICATION
| Standard | Tier | Description |
|---|---|---|
| BS EN 50288-7:2005 | TIER 1 — Product Standard | Instrumentation/control cable construction & performance |
| BS EN 50288-1 | TIER 1 — Generic Specification | Parent generic spec |
| GB/T 9330-2020 | TIER 1 — Product Standard | Control cables |

⚠️ TIER MISMATCH FLAG: BS EN 50288-7 (TIER 1) has no exact TIER 1 GB counterpart. GB/T 9330-2020 and JB/T 13486-2018 are related but not identical product categories. Comparison is cross-category, not like-for-like.

AUDIT FLAG RESOLUTION
- ✅ RESOLVED: GB/T 9330-2020, GB/T 12706.1-2020, GB 31247-2014 all confirmed CURRENT (现行) per official authority. No supersession notes added.
- ⚠️ UNRESOLVED: All numeric values (cross-sections, voltage, temperature) require verification against official texts — clause numbers not confirmed in either source.
- 🔴 CRITICAL CORRECTION: BS EN 50288-7 is NOT a general LV wiring or power cable standard. Any comparison must be cross-category (NEQ/MOD), never IDT.
PROCUREMENT VERDICT
- Do not specify BS EN 50288-7 for Chinese procurement — no GB equivalent exists.
- Re-specify against GB/T 9330-2020 (control) or JB/T 13486-2018 (instrumentation).
- Confirm rated voltage requirement (CN 450/750 V vs EN 300/500 V).
- Verify fire performance against mandatory GB 31247-2014.
- Obtain official standard texts before finalising technical specification.
- Engage a Registered Supervision Engineer (注册监理工程师) for on-site verification.
