Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
EN 15051-2 (Workplace exposure. Measurement of the dustiness of bulk materials - Rotating drum method)
Deviations:
no
GLP compliance:
not specified
Type of method:
rotating cylinder
Sampling:
Sample amount: 14 g
Each sample has been divided in eight equal lots using a rotary riffler, this rotary riffler is especially designed to minimize the loss of any fine dust. One of these divided lots has been used for determining the bulk density and the moisture content.

It can be concluded based on the RSD values of the inhalable and thoracic fractions (≤15 %) that the dustiness potentials of the independent triplicates are highly repeatable. The higher RSD for the respirable fraction is caused by the lower absolute masses of the dust fractions or inhomogeneity of the samples.

Applicant's summary and conclusion

Conclusions:
The fraction of constituent particles with an aerodynamic diameter <10µm in Lumière Pink S.M. 8135N is <1%.
Executive summary:

The dustiness of Lumière Pink S.M. 8135N was determined by EN 15051 - Rotating drum (method 2).
