BS 6387 Standard VS IEC 60331 Standard
Fire-Resistant Cable Standards: Technical Comparison (BS6387 CWZ vs IEC 60331-21)
1. Core Standards Comparison
| Parameter | BS6387 CWZ (UK Standard) | IEC 60331-21 (International Standard) |
|---|---|---|
| Flame Temperature | 950°C (Class C) | 750°C |
| Duration | 180 minutes (Class C) | 90 minutes |
| Water Spray (W) | 650°C flame + 15-minute water spray | Not required |
| Mechanical Shock (Z) | 950°C flame + impacts every 30s for 15min | Not required |
| Voltage | Applied rated voltage (e.g. 300V) | Applied rated voltage |
| Applications | Nuclear plants, tunnels, subways | General building cables (≤1kV) |
| Rigor | Industry's most stringent standard | Basic fire resistance only |
2. Other Key Standards
-
AS/NZS 3013 (Australia/NZ)
-
Designations like WS52W: 1050°C flame + 120min burn + water spray
-
For extreme environments (metallurgy, chemical plants)
-
-
EN 50200 (EU Standard)
-
Similar to BS6387 but simplified (PH30/PH120 ratings)
-
Adds mechanical impact at lower temperatures than BS
-
-
GB/T 19216 (China National Standard)
-
Equivalent to IEC 60331 with added post-fire voltage tests
-
Includes 4000V/5min withstand requirement
-
3. Technical Implications
-
Material Selection
BS6387 CWZ requires mica tape + ceramifiable silicone rubber (15-30% costlier than IEC solutions) -
Testing Methodology
BS6387 simulates real fire scenarios (flame+water+shock), while IEC only tests static burning
4. Industry Trends
-
Hybrid Systems: BS6387 for power lines + IEC 60331-25 for data cables in smart buildings
-
Regulatory Shift: EU projects increasingly demand EN 50200 + mechanical impact
-
Cost Optimization: Non-critical areas may use IEC + LSZH sheathing
For specific compliance data (e.g., mica tape thickness, cable construction), refer to technical documentation.
