Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
particle size distribution (granulometry)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
07 November 2011-17 November 2011
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: The study has been performed according to appropriate guidelines and according to the principles of GLP.
Qualifier:
according to guideline
Guideline:
other: The test was conducted in accordance with ISO 13320:2009 and CIPAC MT 187 and took into consideration OECD guideline 110
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Type of method:
Laser scattering/diffraction
Type of distribution:
volumetric distribution
Mass median aerodynamic diameter:
126.568 µm
Percentile:
D10
Mean:
7.401 µm
St. dev.:
1.81
Remarks on result:
other: Average of 5 runs
Percentile:
D50
Mean:
102.324 µm
St. dev.:
2.65
Remarks on result:
other: Average of 5 runs
Percentile:
D90
Mean:
351.112 µm
St. dev.:
2.12
Remarks on result:
other: Average of 5 runs
No.:
#1
Size:
< 10 µm
Distribution:
12.23 %

Volume weighted Mean: 146.039 µm (average of 5 runs)


Mode: 177.718 µm (average of 5 runs)


Coefficient of variation for d50 is less than 3 %; d10 and d90 are less than 5 %. Thus, repeatability of the characteristic particles in the size distribution are within the acceptable limits as per the ISO 13320-1 test standard.

Conclusions:
Particle Size Analysis (laser diffraction-wet' small volume module) results for FAT 41043/A:
MMAD= 126.568 µm; 10 % is <7.401 µm; 12.23 % is <10 µm; 50 % is <102.324 µm and 90 % is <351.112 µm.

Description of key information

MMAD= 126.568 µm; D50= 102.324 µm; D10= 7.401 µm and D90= 351.112 µm (Laser diffraction analysis-'wet' small volume dispersion method).

Additional information

12.23% by volume is < 10 µm
