Overview
The BS6500 standard previously covered flexible cables, including light-duty and ordinary-duty cables, used in applications such as:
- Pendant lighting drops.
- Portable appliances like radios.
- Domestic and office environments.

These cables are now classified under BS EN 50525, which includes harmonized codes to align with European standards. While BS6500 is no longer a current British Standard, it is still widely referenced in the UK electrical industry. Contractors often use BS6500 names and harmonized names interchangeably.

Key Points to Note

• BS EN 50525 Harmonisation: The introduction of BS EN 50525 aligns the UK's cable standards with European practices, providing a unified approach for cable identification and use.
• Durability: These cables are designed to cater to various environments, including high temperatures, domestic appliances, and office setups.
• Applications: The harmonized cables continue to serve similar functions as their BS6500 counterparts but with updated designations for ease of international use.
• Contractor Practices: Despite the harmonization, many contractors still refer to the original BS6500 designations, highlighting the legacy of the standard in the industry.
