H Class Fire Protection System
Summary：The hydrocarbon fire curve is used for testing Class H fire divisions. Its temperature-time profile is more stringent than the cellulosic fire curve specified in IMO's 2010 FTP Code, both in terms of heating rate and the final achievable temperature. For Class H fire divisions, fire tests shall be conducted in accordance with Part 3 of the IMO FTP Code, with the key difference being that the test furnace is heated using the hydrocarbon fire temperature-time curve instead of the cellulosic fire curve.
