Results and discussion
Particle sizeopen allclose all
- Percentile:
- D50
- Remarks on result:
- other: not applicable(migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.)
- Remarks on result:
- other: As an insignificant proportion of test material was found to be less than 100µm, definitive testing using cascade impactor method was not necessary. Proportion of test materila having a particle size less than 100µm.
Applicant's summary and conclusion
- Conclusions:
- As an insignificant proportion of test material was found to be less than 100µm, definitive testing using cascade impactor method was not necessary. Proportion of test materila having a particle size less than 100µm. As an insignificant proportion of test material was found to be less than 100µm, the test item is considered not to be a potential inhalation hazard.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
