Definition(s)

Class H-120 Division

“Class H-120 division” means a division formed by a bulkhead or deck that is

  2. constructed to prevent the passage of smoke and flame after exposure to a hydrocarbon fire test for 120 minutes, and
  3. insulated with non-combustible material so that, if either face is exposed to a hydrocarbon fire test, after 120 minutes the average temperature on the unexposed face will not increase by more than 139°C above the initial temperature, and the temperature at any point on the unexposed face, including any joint, will not increase by more than 180°C above the initial temperature; cloisonnement de classe H-120.
