Additional information
In accordance with section 2 of REACH, Annex XI, the study does not need to be conducted as the test substance will not melt in the applicability range of EU Method A.1 (in production process melting point >1800 °C).
In the course of the industrial use the test item of the melting point was determined (reference 4.2 -2). The substance is used in an Electron beam evaporator at an evaporation temperature of 2200-2300 °C. Prerequisite to the evaporation step is the preparation of the base melt which requires thorough melting to avoid any remaining loose granules. This melting takes place above 1800 °C. This melting point is out if the applicability domain of the any method cited in the respective OECD or EU guidelines.
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.
