Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Particle size distribution at different passages
>= 0.053 - <= 0.297 mm
Remarks on result:
other: Particle size distribution was determined to be in the range >= 0.053 - <= 0.297 mm.
Particle size distribution determined by sieving through No. 50, No. 100, No. 200 and No. 270 US standard sieves (see under overall remarks).

Applicant's summary and conclusion

The particle size of the test item is in the range between 0.053 mm and 0.297 mm.
Executive summary:

In the Technical Manual, the particle size distribution of the test item determined by sieving is reported: 98% at minimum passed through a No. 50 US standard sieve, 96% through a No. 100 US standard sieve, 25 -90% through a No. 200 US standard sieve, and 0 -15% through a No. 270 US standard sieve. Based on these information, it can be concluded that the test item particle size is in the range between 0.297 mm (corresponding to a No. 50 US standard sieve) and 0.053 mm (corresponding to a No. 270 US standard sieve).
