Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.8 (Partition Coefficient - Shake Flask Method)
- Deviations:
- yes

- GLP compliance:
- no
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Type of method:
- flask method
- Partition coefficient type:
- octanol-water
