Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
other: company data
Adequacy of study:
key study
Study period:
2018-01-17
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Qualifier:

Calculation from 0.04 µm up to 2000 µm

volume: 100 %

mean: 4.175 µm, S.D.: 4.570 µm

median: 2.296 µm

mean /median value: 1.818

maximum: 13.61 µm

< 5 % : 0.353 µm

< 10 % : 0.478 µm

< 25 % : 0.882 µm

< 50 % : 2.296 µm

< 75 % : 5.458 µm

< 90 % : 12.60 µm

< 95 % : 14.74 µm

< 99 % : 17.60 µm

Conclusions:
The particle size distribution of the test item is as follows: D10: 0.478 µm, D50: 2.296 µm (median), D90: 12.60 µm
