Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- ASTM D1293 (Standard Test Methods for pH of Water)
- Principles of method if other than guideline:
- pH measured using a calibrated standard laboratory pH meter. The substance is insoluble and hence the suspension was allowed to settle after one hour mixing and the pH of the supernatent liquor was measured.
- GLP compliance:
- no
