For calculation used density: ρwater at 4 °C = 1.0000 g/cm3
To evaluate the drying conditions of the test item a preliminary test in a melting point device was performed.
Description of key information
The relative density of the substance is determined to be between 3.742 and 4.203 at 20 °C depending on the composition of the substance used.
Key value for chemical safety assessment
Additional information
Two GLP studies were conducted.
For form 1 a GLP study was conducted in accordance with the OECD Guideline for the Testing of Chemicals. 109: "Density of Iiquids and solids". The density was measured by the gas pycnometer method according to DIN EN ISO 1183-3. The relative density was determined to be 4.203 at 20 °C.
For form 4 a was conducted in accordance with the OECD Guideline for the Testing of Chemicals. 109: "Density of Iiquids and solids". The density was measured by the gas pycnometer method according to DIN EN ISO 1183-3. The relative density was determined to be 3.742 at 20 °C.
