Resistance to fire is the property of a material or assembly to withstand fire or give protection from it and it is measured as the time (minutes) a product can maintain a level of functionality during a fire. Fire resistance may be built-in both structurally and by the correct choice and application of building materials.
In particular, the resistance-to-fire (of a cable) is the term used to describe how long a cable continues to operate in a fire. This may be of primary concern, for instance, in life safety of fire fighting installations.For cables, resistance-to-fire concerns:
the ability of a cable to maintain functionality during fire;
the duration of survival in working condition;
one specific cable family: Fire Resistant Cables.
The resistance-to-fire performance of cables is indicated in terms of survival time: the times are 15, 30, 60, 90 and 120 minutes of operation in a standardized fire condition at European Level (CENELEC) and equivalent international (IEC). Local standards and customers' specs include their own requirements which are also achieved by our local or tailor-made products.The resistance-to-fire of buildings products and structures is normally regulated by National Authorities.
