Resistance to fire
What is Resistance to Fire?
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 mantain 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.
The Resistance to Fire of buildings products and structures is normally regulated by
National Authorities. Visit national web sites for further information.
