       Qsb: Heat for sustained burning   持續燃燒熱值

       Qt: Total heat release 熱釋放總值

       Qp: Peak heat release rate 熱釋放峰值

 

測試方法

A specimen with dimensions 800mm x 155mm is exposed in vertical position to a graded radiant heat flux field supplied by a gas-fired radiant panel. The angle between the specimen and the radiant panel is 15°.

The distribution of the heat flux field along the specimen is calibrated at fixed positions 100 mm apart. The values of the heat flux field at these positions as specified in the standard are between 1,5 and 50,5 kW/m2.

Gases given off from the specimen are ignited by a pilot flame from a burner which is situated at the end of the specimen which is nearest to the radiant panel. The combustion gases are drawn off through a fume stack above the specimen.

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.
