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
- Study period:
- 01 February 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- determination of fibre length and diameter distributions
- Type of distribution:
- volumetric distribution
- Specific details on test material used for the study:
- 4,4'-oxydianiline
4,4'-diaminodiphenyl ether
CAS 101-80-4 - Key result
- Percentile:
- D50
- Mean:
- 100 µm
- Remarks on result:
- other: The inhalable fraction is defined as the mass fraction of particles which can be inhaled by nose or mouth.(migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.)
- No.:
- #1
- Size:
- 100 µm
- Distribution:
- 3.01 %
- Remarks on result:
- other: The proportion of test material having an inhalable particle size of less than 100 µm was determined to be 3.01%.
- Conclusions:
- The proportion of test material having an inhalable particle size of less than 100 µm was determined to be 3.01%. The substance is therefore not consdered to pose a hazard by inhalation based on this amount.
- Executive summary:
The proportion of test material having an inhalable particle size of less than 100 µm was determined to be 3.01%. The substance is therefore not considered to pose a hazard by inhalation based on this amount. Furthermore, given the form of the substance imported into the EU, and the inhalable fraction assessed, it is unlikely that the substance will also pose a respirable dust hazard.

Description of key information
The particle size distribution of the substance 4,4'-Oxydianiline was determined according to the OECD Guideline 110, under GLP conditions.
The proportion of test material having an inhalable particle size of less than 100 µm was determined to be 3.01%. The substance is therefore not consdered to be hazardous by inhalation based on this amount.
Additional information
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.
