- Specific details on test material used for the study:
- TREATMENT OF TEST MATERIAL PRIOR TO TESTING
The test item was molten at 78°C. The sample cell was filled with the liquefied test item and cooled in a desiccator under vacuum with silicagel as drying agent at 18.5°C for 25 minutes. - Dynamic viscosity of test material:
- not applicable (substance is a solid at 20°C)
- Key result
- Type:
- relative density
- Density:
- 1.2 other: dimensionless
- Temp.:
- 20 °C
- Remarks on result:
- other: D 20 /4
- Key result
- Type:
- density
- Density:
- 1.2 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The relative density D20/4 of the substance was determined to be 1.20.
- Executive summary:
The relative density of the substance was determined in a GLP study according to EC A.3, OECD 109 and OPPTS 830.7300 (method: air comparison pycnometer (for solids)). A gas comparison pycnometer was used with Helium as the gas. The relative density D20/4 was determined in duplicate obtaining a mean value of 1.20.
