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.
