Workplace exposure. Measurement of the dustiness of bulk materials - Continuous drop method1 Scope This European Standard specifies the continuous drop 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 and respirable fractions of this dust, with reference to existing European Standards, where relevant (see Clause 6). The continuous drop method intends to simulate dust generation processes where there are continuous falling

The principle differences between the two is the fitting of certain cooling equipment and pressure-charging equipment auxiliaries (fans) for the test

thus enabling the achievement of standardized and adequately documented load values

users can assess the efficiency of liming materials
