ST3 Dust Protection

ST3 Dust Protection Class

Kst value greater than 300 bar m/sec

Dust is a solid material that can be highly flammable when in a contained vessel. To separate different dust types based on their Kst value into categorical protection groups, we use classes ST1, ST2 and ST3. This way, we can efficiently identify the best protection to use against dust explosions of varying material types.
