1 Introduction
-
The insulation (I) criterion refers to the ability of maintaining the temperature rise at the unexposed side below predefined temperature limits (average and maximum temperature measurements).
-
The integrity (E) criterion refers to the ability of withstanding the spread of fire by preventing the passage of flames and hot gasses (visual sustained flaming, ignition of cotton wool pad, limitation of gap openings).
