IMO 2010 FTPC Part 5 – Test for surface flammability

Surface flammability testing by IMO 2010 FTP Code Part 5 is to be performed on surface materials to assess their suitability for use in shipbuilding.

The specimen is inserted in the specimen holder together with a substrate. It is vertically positioned during the test and is exposed to a heat radiation panel. The test is conducted with a pilot flame. The time of ignition, the spread of flame, extinguishment of flame, and burning droplets are observed and noted. Also, the following parameters are measured:

• CFE = critical flux at extinguishment (kW/m²)

• Qsb = heat for sustained burning (MJ/m²)

• Qt = total heat release (MJ)

• Qp = peak heat release rate (kW)
