Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: Directive 92/69/EEC, Method A4, Vapour pressure balance method.
- Principles of method if other than guideline:
- The vapour pressure balance oven was charged with test substance (140 mg) and the apparatus assembled and evacuated to a pressure of less than 1x1o-s Torr.
A series of three runs were performed between about 90 to 130°C, the same sample was used for each test and the pressure kept at less than 1x 1o-s Torr throughout. Mass differences, condensation rates and the temperature were monitored by the chart recorder every time the shutter was opened. - GLP compliance:
- yes
- Type of method:
- effusion method: vapour pressure balance
