Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The result shows that the proportion of the test material having inhalable particle size (< 100 µm) is 0.199% indicating that the test material is essentially non-inhalable.
Additional information
The method used is designed to comply with that given in 'Particle Size Distribution, Fibre Length and Diameter Distribution', June 1996 European Commission technical guidance document.
Procedure:
Screening test (sieve method):
Test material (20.10 g) was sieved for approximately 10 minutes with the aid of a sieve brush through a 100 µm sieve. The mass of test material passing through the sieve was measured.
Results:
Screening test (sieve method)
The results of the sieving procedure are shown in the following table:
Sieve Aperture Size (µm) |
100 |
Mass of test material transferred to sieve (g) |
20.10 |
Mass of test material passed through sieve (g) |
0.04 |
Test material less than sieve aperture size (%) |
0.199 % |
Conclusion:
Particle size data acquired for the test material is shown in the following Table:

0.199 % |
The result indicates that the test material is essentially non-inhalable.
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.
