The Fire Attenuation Test (FSZ0688) rates products in the form of a percentage for every unit of heat that it does not permit to pass through it, from one side to the other. The percentage of heat attenuation is calculated every 5 minutes for as long as the test lasts.
Crimsafe Tensile-Tuff® mesh achieved a rating of 45%, confirmed by CSIRO testing. That means that 45% of radiant heat flux and naked flame on one side of a Crimsafe screen does not transfer through the screen.
