Heat flux in jet fires : Unified method for measuring the heat flux levels of jet fires

• Passive fire protection materials are used to protect critical structures against the heat from fires. In process plants with pressurized combustible substances there may be a risk of jet fires. Through risk analysis the severity of these jet fires is determined and these result in fire resistance requirements with different heat flux levels for different segments. The relevant test standard for fire resistance against jet fires does not include any measurements or definitions of the heat flux in the test flame which the tested object is exposed to. This paper presents methods for reaching different heat flux levels and how to measure them in a jet fire with limited deviations from the established jet fire test standard.
