- no
- Type of method:
- pycnometer method
- Key result
- Type:
- relative density
- Density:
- 1.081 other: compared to water at 4 °C
- Temp.:
- 20 °C
- Conclusions:
- The density of the test item was determined to be 1.0806 g/cm³ (= 1080.6 kg/m³) at 20°C, corresponding to a relative density of 1.0806.
- Executive summary:
The relative density of the test item was determined by pycnometer method according to guidelines OECD 109, EU A.3 and OPPTS 830.7300. The density of the test item was determined to be 1.0806 g/cm³ (= 1080.6 kg/m³) at 20°C, corresponding to a relative density of 1.0806. The study was not performed in compliance with GLP, however the test facility was GLP-compliant. The study is considered to be reliable without restrictions (Klimisch 1).

Additional information
The relative density of the test item was determined according to guidelines OECD 109, EU A.3 and OPPTS 830.7300 (2016) by pycnometer method. The study was not performed in compliance with GLP, however the test facility was GLP-compliant. The study is considered to be reliable without restrictions (Klimisch 1).
