- Conclusions:
- For the test item LUMULSE GMT-K, the following vapour pressures at 20 °C and at 25 °C were calculated from the regression equation:
Vapour pressure at 20 °C: 1.00 * 10-03Pa
Vapour pressure at 25 °C: 1.32 * 10-03Pa - Executive summary:
Determination of the Vapour Pressure of LUMULSE GMT-K according to OECD 104 resp. EU A.4 using the effusion method: Knudsen Cell.
Findings and Results:
The vapour pressure of LUMULSE GMT-K was determined according to OECD 104 resp. EU A.4 using the effusion method (weight loss).
Vapour pressure was examined at nine different temperatures. Eight temperatures could be evaluated as they showed reproducible weight loss. For these temperatures, 1/T was plotted against log (p).

Description of key information
For the test item LUMULSE GMT-K, the following vapour pressures at 20 °C and at 25 °C were calculated from the regression equation:
Vapour pressure at 20 °C: 1.00 * 10-03Pa
Vapour pressure at 25 °C: 1.32 * 10-03Pa
Key value for chemical safety assessment
- Vapour pressure:
- 0.001 Pa
- at the temperature of:
- 25 °C
Additional information
The vapour pressure of LUMULSE GMT-K was determined according to OECD 104 resp. EU A.4 using the effusion method (weight loss).
Vapour pressure was examined at nine different temperatures. Eight temperatures could be evaluated as they showed reproducible weight loss. For these temperatures, 1/T was plotted against log (p).

The graph 1/T vs. log (p) shows a straight line with a correlation coefficient of - 0.9923.
For the test item LUMULSE GMT-K, the following vapour pressures at 20 °C and at 25 °C were calculated from the regression equation:
Vapour pressure at 20 °C: 1.00 * 10-03Pa
Vapour pressure at 25 °C: 1.32 * 10-03Pa
