| IMO FTPC Part 5: Test for surface flammabilityIMO FTPC Part 5: 表面可燃性测试
   Field of application  Surface materials for bulkheads and ceilings and similar exposed surfaces, floor coverings    等级评估: 
| Bulkhead, wall and ceiling linings | Floor coverings  |  
| CFE         Qsb     Qt      Qp Kw/m2    MJ/m2   MJ     kW | CFE      Qsb       Qt      Qp Kw/m2  MJ/m2    MJ      kW |  
| ≥20       ≥1.5     ≤0.7     ≤4.0 | ≥7.0     ≥0.25    ≤2.0    ≤10.0 |  Where CFE: Critical flux at extinguishment 熄灭时临界热辐射量        Qsb: Heat for sustained burning   持续燃烧热值        Qt: Total heat release 热释放总值        Qp: Peak heat release rate 热释放峰值   The test is terminated when any one of the following is applicable; 1.      The specimen fails to ignite after a 10 minute exposure 2.      Three minutes have pass since all flaming from the specimen ceased. 3.      Flaming reaches the end of the specimen or self extinguishes and thus ceases to progress along the specimen. This criterion is only used when heat release measurements are not being made. 4.      In the case of floorcoverings, the test shall be terminated after 40 minutes.
