BS EN 13381-3 and BS EN 13501-2

Up to 240 minutes fire resistance

The BS EN 13381-3 regards the fire resistance of concrete structures and the performance of the intumescent coatings applied on concrete are expressed in terms of equivalent concrete thickness.

The method defines the quantities (in gr/m2 ) of intumescent coating required to achieve the same insulation performance provided by different thicknesses of concrete.

The calculation of the equivalent concrete thickness required for slabs and walls exposed to fire on one side is based on fire test results achieved on loaded slabs having minimum (500 gr/m2 ) and maximum (2035 gr/m2 ) applied quantity of intumescent coating. Linear interpolation between minimum and maximum is allowed.
