W3 = Mass of test item added to pycnometer
W4 = Mass of displacement liquid required to fill pycnometer containing W3g of test item
W5 = Mass of displacement liquid equivalent to W3g of test item
ptl= density of displacement liquid at temperature of determination (g/mL)
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 1.05 at 20 °C.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.05
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.
