How are blast doors rated?
Unlike an A-rated fire rated door which is rated on the normal ISO standard fire temperature curve a blast rated door is tested using the Hydrocarbon fire curve. This is the reason why blast doors are given a rating of H0-H120. H-rated doors are tested at higher temperatures over a longer time period than A-rated fire doors.
How can a blast-rated door help during an explosion and subsequent fire?
Blast doors are designed to withstand significant increases in pressure that may occur as a result of an explosion within a room. In the event of an explosion, blast doors will be subject to an initial “positive phase” (the outward pushing force of the explosion) followed by an inward pulling, “negative phase”. The blast doors provided by Nucore Group are designed to withstand these phases as well as provide an amount of protection from any subsequent fire that may occur as a result of the explosion.
