- Storage condition of test material: Ambient
- Type:
- relative density
- Density:
- 0.93 other: dimensionless
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item was determined to be 0.93.
- Executive summary:
The density study was conducted according to OECD guideline 109 (Dunning 2018). The density of the test item relative to water at 4°C was determined using the pycnometer method. The test was conducted in duplicate using separate pycnometers.
The relative density of the test item was determined to be 0.93.
The study is GLP-compliant and was conducted according to the standard guideline, therefore is considered reliable without restrictions and suitable as a key study for this endpoint.
