When conducting dust explosion hazard assessment and dust explosion prevention design in workplaces involving dust, it is necessary to conduct testing of dust explosion parameters.

Common dust explosion parameter testing items include:

Dust explosiveness test (Hartmann tube, 20L ball)

Lower limit of dust explosion LEL (20L ball)

Minimum ignition energy MIE (Hartmann tube) for dust clouds

Thermogravimetric Differential Scanning Calorimetry (TG/DSC)

Dust explosion index Kst (20L ball)

Maximum pressure Pmax for dust explosion (20L ball)

Minimum ignition temperature of dust cloud MIT-C (G-G furnace)

Minimum ignition temperature of dust layer MIT-L (hot plate furnace)

Dust layer resistivity
