Materials and methods
Test guidelineopen allclose all
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7220 (Boiling Point / Boiling Range)
- Deviations:
- no
- Principles of method if other than guideline:
- For the determination of the boiling point, the capillary method according to Siwoloboff was used. A small amount of the test item was heated in the electronic controlled sample block and the temperature of around the sample was displayed. The sample was observed visually while raising the temperature. A phase transformation from liquid to vapour usually is deduced by the formation of steam bubbles leaving the inserted boiling capillary.
The test item was assessed visually for any possible changes in its appearance, consistency and colour. The initial temperature of boiling or other effects observed were registered with the correspond-ing heating temperature - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: Capillary method using electronic controlled heating system
