Smoke and heat emissions from boundaries of fire compartments and the impact of installation methods
A B S T R A C T Fire resistance testing is intended to provide criteria and verification methods for stopping of fire spread between fire compartments. It has been used with success for this purpose for decades. The principle, testing schemes, and criteria do not provide information about tenability conditions in adjacent fire compartments however. This drawback has become increasingly obvious as fire safety engineering started to make it possible to evaluate tenability conditions using data on smoke emissions from construction materials and products, and as construction products with potency to emit significant amounts of opaque and toxic effluents found the way to building systems including those providing fire resistance. Findings of fire resistance testing of six non loadbearing walls made of commonly used composite metal faced sandwich panels, two filled with mineral stone wool as core insulation (MW) and four filled with polymer polyisocyanurate (PIR) insulation material, demonstrated these effects. The project has been recently expanded by additional measurements of gas and particle effluents. This paper deals with new information reflecting back on original test results.
