STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Ambient
- Stability under test conditions: Stable under recommended storage conditions. - Type:
- relative density
- Density:
- 0.972
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item was determined to be 0.972 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 (Dunning 2019). The relative density of the test item was determined to be 0.972 at 20°C.
The study is a GLP compliant, guideline experimental study and is fully acceptable for assessment of this endpoint.
