What is the International standard for cable cleats?

IEC 61914 Cable cleats for electrical installations outlines a series of tests that can be used to assess the performance of a cable cleat’s design.

Although the standard does not define pass or fail levels, it allows manufacturers to define the performance characteristics of their products, and specifiers to compare products from different manufacturers.

The aspects of construction and performance covered by the standard include:

  • Material type – i.e. metallic, non-metallic or composite
  • Minimum and maximum declared service temperatures
  • Resistance to impact at the minimum declared operating temperature
  • The ability of the cable cleat to withstand axial slippage forces
  • Resistance to electro-mechanical forces – i.e. the ability of the cable cleat to withstand the forces between the cables in the event of a short-circuit
  • Resistance to UV and corrosion
  • Flame propagation
