- Conclusions:
- The D50 of this substance is 61.6 μm, D10 is 7.47 μm, D90 is 352.0 μm.
13.69 % by volume of sample was seen to be < 10.00 μm. - Executive summary:
The test is conducted in accordance with ISO 13320:2009 "Particle Size Analysis – Laser Diffraction Methods", 2009 and CIPAC MT 187 "Particle Size Analysis by Laser Diffraction", Handbook K, 2007 to determine the particle size distribution of test item.
The D50 of this substance is 61.6 μm, D10 is 7.47 μm, D90 is 352.0 μm.
13.69 % by volume of sample was seen to be < 10.00 μm.
Reference
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.
Description of key information
The D50 of this substance is 61.6 μm, D10 is 7.47 μm, D90 is 352.0 μm.
Additional information
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.
