This method is for the determination of the ignitability of solids and is also applicable for pastes, granular materials, solids that can be cut into strips, and powdery substances. The test material is formed into an unbroken strip of powder train 250mm in length. An ignition source is applied to one end of the test material to determine whether combustion will propagate along 200mm of the strip within a specified time period. Materials that propagate burning along a 200 mm strip within the specified time period are then subjected to a burning rate test. Materials that do not ignite or propagate combustion as described above do not require further testing. In the burning rate test, the burning time is measured over a distance of 100mm and the rate of burning is determined.
All samples should be tested on an as-received basis.
