- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- <= 0 Pa
- Conclusions:
- The test material has been determined to have a vapour pressure of less than or equal to 4.3 x 10^-5 Pa at 20ºC and less than or equal to 1.1 x 10^-4 Pa at 25ºC by the isothermal thermogravimetric effusion method.
- Executive summary:
The test procedure was Method 104 specified in the OECD Guidelines for Testing of Chemicals.
The vapour pressure of the test item was determined by the isothermal thermogravimetric effusion method. The weight loss of the test item was measured continuously as a function of time at defined isothermal temperatures. The evaporation rate of the test item was calculated from the weight loss of the compound.
The test material has been determined to have a vapour pressure of less than or equal to 4.3 x 10^-5 Pa at 20ºC and less than or equal to 1.1 x 10^-4 Pa at 25ºC by the isothermal thermogravimetric effusion method.
