This European Standard specifies the rotating drum test apparatus and associated test method for the reproducible production of dust from a bulk material under standard conditions, and the measurement of the inhalable, thoracic and respirable fractions of this dust, with reference to existing European Standards, where relevant (see Clause 6).
This method is suitable for general bulk material handling processes, including all those processes where the bulk material is dropped, or can be dropped. It differs from the continuous drop method presented in EN 15051 3 in this European Standard, the same bulk material is repeatedly dropped, while in EN 15051 3, the bulk material is dropped only once, but continuously.
Furthermore, this European Standard specifies the environmental conditions, the sample handling and analytical procedures, and the method of calculating and presenting the results. A classification scheme for dustiness is specified, to provide a standardised way to express and communicate the results to users of the bulk materials.
This European Standard is applicable to powdered, granular or pelletised bulk materials. A standard sample volume is used.
This European Standard is not applicable to test the dust released when solid bulk materials are mechanically reduced (e.g. cut, crushed) or to evaluate handling procedures for the bulk materials.
