- Key result
- Type:
- relative density
- Density:
- 0.981 other: dimensionless
- Temp.:
- 20 °C
- Type:
- density
- Density:
- 0.981 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The relative density at 20°C of the substance was determined to be 0.981.
- Executive summary:
The relative density was determined using a volume pycnometer in a GLP study according to EC A.3, OECD 109 and OPPTS 830.7300. The relative density was determined in duplicate at 20°C obtaining a mean value of 0.981.
