Particle size distribution (Granulometry)
Administrative data
Link to relevant study record(s)
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- DIN 55992-1 (Determination of a parameter for the dust formation of pigments and extenders - Part 1: Rotation method)
- Deviations:
- yes
- Remarks:
- DMT modified the Heubach dust meter in a way that a seven-stage cascade impactor was inserted instead of the filter. This will allow to separate inhalable, thoracic and avleolar dust fractions as defined in DIN EN 481
- GLP compliance:
- no
- Type of method:
- rotating drum method
- Type of particle tested:
- primary particle
- Type of distribution:
- mass based distribution
- Specific details on test material used for the study:
- The humidity of the substance was 0.7% as determined by drying the sample in a furnace in accordance with DIN 18121-1: a part of the sample was weighed in a weighing glass and then dried in the drying cupboard at approx. 105°C for approx. 4 hours until constancy of weight was attained. The sample was weighed after cooling in a desiccator.

- Conclusions:
- The most important result of this examination is, that for FUMFL 264-276 REACH, the respirable fraction represent 2.09 % of used quantity of the substance under the modified Heubach procedure.
- Executive summary:
Examinations were performed to determine the dustiness of a substance sample designated as " FUMFL 264-276 REACH ". The objective of these examinations was to determine the dust fractions of this substance. These are the dust fractions which are defined in DIN EN 481 as the inhalable fraction, thoracic fraction and the respirable fraction.
The modified Heubach procedure was applied. In the process, the substance sample was mechanically stressed in a rotating drum (dust generation device), and both the dust already contained in this sample and the dust generated due to abrasion were removed from the dust generation device by an air current. The proportion of dust separated and considered as dust with the ability to become airborne was fed into a seven-stage cascade impactor connected to the dust generation device. Particle size classification was conducted by subsequent weighing of the respective dust masses deposited on the individual cascade stages reflecting certain particle size ranges.
The most important result of this examination is, that for FUMFL 264-276 REACH, the respirable fraction represent 2.09 % of used quantity of the substance under the modified Heubach procedure.
