- Executive summary:
Method
The substance has been tested for density according to the OECD Guideline 109. Density was calculated from the difference in weight between the full and empty pycnometer and its volume.
Result
The substance shows a relative density of 1.419 at 20 °C.
Reference
Absolute density of a substance (δ) is calculated as:
δ subs = WS / V subs = WS / (V pyc – V hex ) = WS / (V pyc – WH2 / δ Hex ) = WS / (V pyc – WH 2 * V pyc / WH1 ) Relative density (D204) is calculated as: δ subs / 0.999973
