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:
- April 18, 2017 to April 18, 2017
- 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) - Method B: Fibre Length and Diameter Distributions
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7520 (Particle Size, Fiber Length, and Diameter Distribution)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- sieving
- Type of particle tested:
- primary particle
- Type of distribution:
- mass based distribution
- Remarks on result:
- not measured/tested
- Key result
- Percentile:
- other:
- Mean:
- > 45 - < 125 µm
- Remarks on result:
- other: Approximately 93% of the test substance had particles residing in the range from 125 to 45 microns.
- Conclusions:
- The test material was a powder. The average amount of particulate matter either at or larger than 250 microns in the test substance was approximately 1%. Approximately 93% of the test substance had particles residing in the range from 125 to 45 microns. The average amount of particulate matter smaller than 20.0 microns in the test substance was approximately 0.2%. The mean weight percent recovery for the two analyses was 100%.
- Executive summary:
Particle size distribution testing was performed on the test substance in duplicate using the powder sieve method according to OECD guideline 110 and EPA Method OPPTS 830.7520. The test material was a powder. The average amount of particulate matter either at or larger than 250 microns in the test substance was approximately 1%. Approximately 93% of the test substance had particles residing in the range from 125 to 45 microns. The average amount of particulate matter smaller than 20.0 microns in the test substance was approximately 0.2%. The mean weight percent recovery for the two analyses was 100%.
Reference
The average amount of particulate matter either at or larger than 250 microns in the test substance was approximately 1%.
The average amount of particulate matter smaller than 20.0 microns in the test substance was approximately 0.2%.
The mean weight percent recovery for the two analyses was 100%.
