ABSTRACT
Coffee Break Training: Building Construction: Part 4: How Fire Resistance Ratings are Measured [open pdf - 0B]
"Will a four-hour fire wall really resist the spread of heat and flames for 240 minutes? Will a two-hour floor/ceiling assembly truly prevent vertical fire spread for 120 minutes while a highrise building is evacuated? The answer is definitely 'maybe' and depends upon the actual fire exposure conditions. In order to obtain an hourly fire-resistance rating, sample fire assemblies must undergo rigorous testing under controlled laboratory conditions. These conditions may not match real world environments found in buildings."
