Facts on Flammability

Slide 26 of 37

The choice of ignition source is one of the most basic variables.

Considerations include its intensity and duration.

As we discussed its location also impacts performance.

And in composite testing, when the ignition source is applied to the sample, close observation is required to determine whether the component of the sample that first sees ignition becomes a secondary and potentially larger ignition source on its own. In many cases the ignited fabric can be a much larger ignition source than the test flame.
