IEC 61914: Assessing Cable Cleat Performance
IEC 61914, which covers cable cleats for electrical installations, outlines a series of tests to assess a cable cleat’s performance. Although the standard does not define pass or fail levels, it allows manufacturers to specify the performance characteristics of their products, enabling specifiers to compare products from different manufacturers.
Key Aspects of Construction and Performance
The standard covers several crucial aspects of construction and performance, including:
- Material Type: Metallic, non-metallic, or composite
- Service Temperatures: Minimum and maximum declared service temperatures
- Impact Resistance: Ability to withstand impact at the minimum declared operating temperature
- Axial Slippage Resistance: Ability to withstand axial slippage forces
- Electro-Mechanical Force Resistance: Ability to withstand forces between cables during a short-circuit
- UV and Corrosion Resistance
- Flame Propagation
