Any other information on results incl. tables

Test temperature: 20.0°C +/- 0.5°C

Headspace vapour concentrations of Octenyl Decenoate as found after an equilibration time of 30 h, 48 h and 54 h are exposed in the table below:

 Equilibration time (h)  Headspace concentration (µg/l)  Headspace concentration (g/m3)
 30  0.27  0.0003
 48  0.30  0.0003
 54  0.34  0.0003

Applicant's summary and conclusion

Conclusions:
The vapour pressure at 20°C was calculated from the average headspace concentration using equation 1 (see paragraph 3.4).
The result was 0.003 Pa.
Therefore:
Vapour pressure of Octenyl Decenoate: 0.003 Pa at 20°C
Executive summary:

The vapour pressure of the test material Octenyl Decenoate has been determined to be 0.003 Pa at 20°C using the Gas saturation method.

Therefore:

Vapour pressure of Octenyl Decenoate: 0.003 Pa at 20°C.
