Scope

This document describes the risk assessment of combustible dust explosions, the determination method of combustible dust, the measurement method of the maximum explosion pressure and the maximum pressure rise rate of dust clouds, the determination method of the lower explosive concentration of dust clouds, the determination method of the electrical resistivity of dust layers, the determination method of the minimum ignition temperature of dust layers, the determination method of the limit oxygen concentration of dust clouds, and the determination method of the auto-ignition temperature of accumulated dust.
This document is applicable to the risk assessment and experimental determination of combustible dust characteristics in enterprises with dust explosion hazards.
This document is not applicable to the risk assessment and related dust characteristic parameter testing of dust sites in coal mines, fireworks, explosives, and strong oxidants.
