What is Combustibility Testing?

Combustibility testing is a critical component of dust hazard analysis that determines the explosion characteristics of combustible dusts. These tests provide essential data for designing appropriate explosion protection systems and ensuring compliance with safety standards.

Our laboratory testing services follow international standards including ASTM E1226 and provide accurate measurements of key parameters such as Kst (deflagration index) and Pmax (maximum explosion pressure) values.

Key Testing Parameters

📊

Kst Value

Deflagration index indicating the rate of pressure rise during dust explosion, crucial for vent sizing calculations.

💥

Pmax Value

Maximum explosion pressure reached during dust explosion, essential for equipment design and protection system sizing.

🔥

Minimum Ignition Energy

Minimum energy required to ignite a dust cloud, important for electrical equipment selection and static electricity control.

🌡️

Minimum Ignition Temperature

Lowest temperature at which dust can ignite, critical for hot surface temperature control and equipment selection.

💨

Minimum Explosive Concentration

Lowest dust concentration that can sustain an explosion, important for dust control and ventilation design.

⚡

Electrical Resistivity

Electrical properties of dust affecting static electricity buildup and discharge, crucial for explosion prevention.
