Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: DIN 38404-5 mod.
- Principles of method if other than guideline:
- The modification of method DIN 38404-5 is due to a sample preparation step. As the pH-value is
defined in an aqueous matrix only the sample (10 %) had to be extracted with deionised water (90 %)
first and the measurement was done in the water phase afterwards. - GLP compliance:
- no

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
