STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: in cool, well-ventilated area - Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 0.017 mBar
- Remarks on result:
- other: The result is the mean of 2 runs.
- Conclusions:
- The vapour pressure of the substance was interpolated from the vapour pressure curve to be 0.017 mbar (1.7 Pa) at 20°C
Reference
Based on the vapour pressures measured, a vapour pressure curve was constructed (lnP vs 1/T; p in mbar and T in Kelvin). The temperature range was 18.7 °C - 64.8 °C and 18.6 °C - 70 °C for run 1 and run 2, respectively.
The vapour pressure at 20°C was interpolated from the vapour pressure curve to be 0.017 mbar (run 1) and 0.016 mbar (run 2 ).
Description of key information
The vapour pressure of the test substance was determined in a GLP-compliant study according to test method EC A.4 to be 1.7 Pa at 20 °C, following the static technique (Younis S, 2012).
Key value for chemical safety assessment
- Vapour pressure:
- 1.7 Pa
- at the temperature of:
- 20 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
