IMO FTPC Part 5:表面可燃性测试

IMO FTPC Part 5: Test for surface flammability
IMO 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:

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.
