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: 15 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.

Summary of the dustiness data of sample Lumière Pink SM 0245N 041020 according to EN 15051, measured at a relative humidity of 47 %.
| Sample mass | Inhalable fraction | Thoracic fraction | Respirable fraction | ||||
| g | mg | mg/kg | mg | mg/kg | mg | mg/kg | |
| 1st test | 15.1812 | 152.8 | 10065 | 32.8 | 2162 | 6 | 393 |
| 2nd | 14.4727 | 124.7 | 8059 | 26 | 1682 | 4.2 | 270 |
| 3rd | 15.0457 | 124 | 8242 | 25.2 | 1674 | 3.7 | 234 |
| Average | 8789 | 1839 | 302 | ||||
| RSD % | 12.60% | 15.20% | 26.50% | ||||
| Classification | High | High | High | ||||
Moisture content: 1.71 %
Bulk density: 399.2 kg m-3
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:
- Lumière Pink SM 0245N is classified as high for all three fractions (Inhalable dustiness, Thoracic dustiness, Respirable dustiness)
- Executive summary:
The dustiness of Lumière Pink SM 0245N was determined by EN 15051 - Rotating drum (method 2)
