Fire Rated Cable Cleats

Currently there are no European or IEC Standards for fire rated cable cleats and cable cleat systems – however requirements exist within other standards that can be adopted to prevent unsuitable cable supports, fixings or cleats being installed or specified where fire performance is vital.

The IEC61914 international standard requires non-metallic and composite cable cleats to have adequate resistance to flame propagation.

UL94, the standard for Safety of Flammability of Plastic Materials for Parts in Devices and Appliances, is a plastics flammability standard that classifies plastics according to how they burn in various orientations and thicknesses. Adherence to its V-O rating for polymers should be demanded by specifiers to ensure safe installation of cable cleats to clamp fire performance and fire resistant cables. UL94 V-0 rating means that burning stops within 10 seconds on a vertical specimen: drips of particles allowed as long as they are not inflamed.

The use of the description LSF (Low Smoke Fume) is common terminology with respect to polymers, but is misleading as it does not relate to a published standard and so can be interpreted in a wide variety of ways.
