Flammability is the ease with which a combustible substance can be ignited, causing fire or combustion or even an explosion.
The degree of difficulty required to cause the combustion of a substance is quantified through fire testing.
Internationally, a variety of test protocols exist to quantify flammability.
Flammability test methods include:
- Hot Wire
- Needle Flame
- Bunsen Burner
- Oven testing methods
