- Density:
- 1 other: unitless
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item was determined to be 1.00 at 20°C.
- Executive summary:
The relative density of the test item was determined in a study following OECD 109 and EC Method A.3 guidelines, using the pycnometer method. The relative density of the test item was determined to be 1.00 at 20°C.
The study is a GLP-compliant, guideline experimental study and is fully acceptable for assessment of this endpoint.

Where:
w1= weight of empty pycnometer (g)
w2= weight of pycnometer and water (g)
w3= weight of pycnometer and test item (g)
w4= weight of pycnometer, test item and water (g)
Dt4= relative density of test item at test temperature compared to water at 4°C
Description of key information
The relative density of the test item was determined to be 1.00 at 20°C.
Key value for chemical safety assessment

- 1
Additional information
The relative density of the test item was determined in a study following OECD 109 and EC Method A.3 guidelines, using the pycnometer method (Dunning 2018).
The study is a GLP-compliant, guideline experimental study and is fully acceptable for assessment of this endpoint.
