Abstract The release of particles from bulk materials is usually an undesired quality. Nevertheless, it can occur in a wide range of material‐handling processes and may present a hazard to humans and the environment. Therefore, the dust formation tendency represents an important material property that depends on the specific type of stress. A forecast of the dust formation tendency could simplify and expedite the assessment of possible hazard potentials as it would eliminate the need for comprehensive dustiness measurements. A single‐drop method was used to analyze the dustiness of nine materials at low pressure conditions. Based on the experimental results, an empirically derived apparatus‐specific forecast parameter and a prediction function were developed.
