Fire resistance tests refer to testing of systems designed to contain or resist fire over a specified period of time. They are very different to reaction to fire tests but are sometimes confused. Fire resistance classifications are often expressed as a period of time such as ‘1 hour fire resistance’ or two numbers such as 30/30 or a combination of letters and numbers such as EI30 or FR60. It is important to understand what each classification means.

When it comes to fire resistance, the most common elements to consider are integrity (E), insulation (I), heat radiation (W) and load bearing capacity (R).

A suite of tests are applicable to fire resistance including LPCB LPS 1208, BS 476-22, and EN 13501-2.
The pictures below illustrate the test rig for fire resistance. Typically speaking the test rig will be 3m wide by 3m tall. Behind the unexposed surface of the insulated panel is a large furnace, which presents a large fire source to the exposed surface of the insulated panel system. Thermocouples are attached to the unexposed surface face, measuring temperature.
