Applicant's summary and conclusion
- Conclusions:
- The GLP study was performed according to EU method A.3 without deviations and therefore reliability of Klimisch 1 has been assigned. The bulk density has been determined to be 0.399 g/mL.
- Executive summary:
The bulk density of 0.399 g/mL of the test substance was determined in a GLP test according to DIN EN ISO 697. The mass of the empty vessel was determined. The funnel of the filling equipment was filled with the substance. The vessel was placed under the funnel and the closing plate was removed. The substance fell down in the vessel. The overlaying substance was removed by a scraper, so that the vessel was completely filled without overlying. The mass of the filled vessel was determined and the mass of the substance inside the vessel was calculated by subtraction of the mass of the empty vessel. The bulk density was calculated by dividing the mass of the substance by the volume of the vessel. The determination was repeated one time.
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.
