Applicant's summary and conclusion

Conclusions:
The vapour pressure of the test substance at 140.0/210°C was determined to be 20/225 mbar.
Executive summary:

The determination of the vapour pressure was based on the following guideline: OECD guidelines for testing chemicals, Guideline No.104: "Vapour pressure curve", adopted May 12, 1981. The vapour pressure curve was constructed using the determination of the vapour pressure of Dihydro-C14 -aldehyde between 120 and 240 °C, using the dynamic Technique. The vapour pressure of Dihydro-C14 -Aldehyde was interpolated to be 20 mbar at 140.0 °C.
