- Executive summary:
Following the dry sieve analysis of the test item potassium cyanate, no particles with a diameter below 25 µm were found. 0.5 % of the particles had a diameter between 25 µm and 50 µm. About 96 % of the particle showed a diameter greater than 75 µm. 11.6 % of the particles were greater than 500 µm.

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.
