- Qualifier:
- according to guideline
- Guideline:

- Principles of method if other than guideline:
- The vapour pressure of the test substance itself was considered to low as to be determinable with the effusion method. As the melting point of the test substance was determined with 235 to 242 °C (508.2 to 515.2 K) under decomposition, the result is plausible and a calculated value is applicable. Therefore, also calculation was performed using the modified Grain-Watson Method with the software EPISUITE Vers. 4.1 by the Environmental Protection Agency (US EPA).
- GLP compliance:
- no
- Type of method:
- effusion method: by loss of weight or by trapping vaporisate
