Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: EC Directive 92/69/EEC, Method A1 (metal block)
- Principles of method if other than guideline:
- The instrument was calibrated using the melting range of benzoic acid (121.5°C - 123.5°C) and found to be 122.5°C- 124.3°C. The heating rate was also checked and found to be 1.0°C/min
Dried test substance (ca 1 g) was pulverized to a fine powder, using a pestle and mortar, and a small amount tightly packed into a capillary tube to a height of 1 mm. The melting point apparatus was set
at approximately 1ooc below the expected melting temperature. The capillary tube was placed in the
apparatus and heated at 1°C/minute until melting was completed.
The procedure was performed three times using a fresh sample on each occasion - GLP compliance:
- yes
- Type of method:
- other: Metal Block
