Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- effusion method: by loss of weight or by trapping vaporisate
- Temp.:
- 20 °C
- Vapour pressure:
- 0 Pa
- Temp.:
- 25 °C
- Vapour pressure:
- 0 Pa
- Conclusions:
- In a GLP-study according OECD Test Guideline 104, the vapour pressure of the registered substance was determined as 1.62* 10-06Pa at 20°C.
- Executive summary:
The Vapour Pressure of CARDOLITE NC-513 was determined according to OECD 104 resp.EU A.4 using the effusion method (weight loss).
Vapour pressure was examined at nine different temperatures. Four temperatures could be evaluated as they showed relevant and reproducible weight loss. For these temperatures, 1/T was plotted against log (P).

For the test item CARDOLITE NC-513, the following vapour pressures at 20 °C and at 25 °C were calculated from the regression equation:
Vapour pressure at 20 °C:1.62* 10-06Pa
Vapour pressure at 25 °C:3.10* 10-06Pa
