Particle size distribution (Granulometry)
Administrative data
Link to relevant study record(s)
Description of key information
Proportion of inhalable particle size (<100 µm): 75.9%, Sieve method; Proportion of thoracic particle size (<10.0 µm): 0.10%, Cascade impactor method; Proportion of respirable particle size (<5.5 µm): 0.05%, Cascade impactor method
Additional information
Particle size distribution of test item was investigated using a procedure designed to comply with the European Commission technical guidance document 'Particle Size Distribution, Fibre Length and Diameter Distribution' (June 1996). This procedure was in accordance with OECD Guideline 110 and the Council Directive 91/414/EEC, Annex 111 as amended in Commission Directive 94/37/EC, Annex I and Annex 11.
The following results for the particle size distribution of test substance were obtained in the screening test (sieve method) and the definite test (cascade impactor method):
Fraction |
Method |
Results |
Proportion of the test item having an inhalable particle size <100 µm |
Sieve |
75.9% |
Proportion of the test item having an inhalable particle size < 10.0 µm |
Cascade impactor |
0.10% |
Proportion of the test item having a respirable particle size < 5.5 µm |
Cascade impactor |
0.05% |
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
