Any other information on results incl. tables
The volume-rated particle size distribution was analysed by laser diffraction method (adopted from ISO 13320:2009) for the same lot in parallel (repeatability in accordance with ISO 13320):
D(0.1): 1.53 µm
D(0.5): 16.3 µm
D(0.9): 51.4 µm
Applicant's summary and conclusion
- Conclusions:
- The dustiness of 4,4'-diamino[1,1'-bianthracene]-9,9',10,10'-tetraone was determined according to EN15051-2. The inhalable, thoracic and respirable dustiness were determined as 'high'.
- Executive summary:
The dustiness of 4,4'-diamino[1,1'-bianthracene]-9,9',10,10'-tetraone was determined according to EN15051-2. The inhalable, thoracic and respirable dustiness mas fractions were determined as 14513 mg/kg, 6209 mg/kg and 4119 mg/kg, respectively. This corresponded to categorisation as high dustiness for all fractions.
