NBN EN 15051:2006

This document specifies the two reference test apparatuses and reference test methods 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 the existing CEN standards, where relevant (see Clause 6).
This document specifies the environmental conditions, the sample handling and analysis 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.
In Annex D, a test method is described that enables dustiness information produced by test methods other than these two reference test methods to be related to that produced using these standard reference test methods.
This document is applicable to powdered, granular or pelletised materials. A standard sample volume is used.
This document is not applicable to test the dust released when solid materials are mechanically reduced (e.g. cut, crushed) or to test handling procedures for the materials.
