How do you determine if dust is combustible?

Combustibility is determined through specialized laboratory testing that evaluates how dust behaves under ignition conditions. Key metrics such as Kst and Pmax values are used to measure how rapidly pressure can build and how intense an explosion could be. These tests simulate real-world scenarios to assess whether dust can ignite and propagate a deflagration. The results are critical for determining the need for explosion protection, system design modifications or compliance with safety standards. Without this data, it is difficult to accurately assess combustible dust risk.
