Calculation of relative density: D204 = 0.876/0.99997 = 0.876
Description of key information
Relative density: 0.876 at 20°C (OECD 109)
Key value for chemical safety assessment
- Relative density at 20C:
- 0.876
Additional information
A relative density value of 0.876 at 20°C was determined for the substance using an oscillating densimeter method in accordance with OECDTest Guideline 109 and in compliance with GLP. The result is considered to be reliable and is selected as key study.
The key study is supported by another measured relative density value of 0.876 at 20°C using an oscillating densitometer in accordance with relevant test method and in compliance with a known quality system (ISO 9001:2008). The supporting study is in agreement with the key study.
In a secondary source to which reliability could not be assigned, a density value of 0.8759 g/m3 at 20°C was reported for the substance.
