Applicant's summary and conclusion

Conclusions:
The vapour pressure of the test item DIMETHYLSULFOXIDE D6 was calculated as 92 Pa at 20.0 °C and 116 Pa at 25 °C.
Executive summary:

The vapour pressure of DIMETHYLSULFOXIDE D6 was measured using the static method according to OECD 104 resp. EU A.4. Ten pairs temperature/vapour pressure were used to calculate a regression from which vapour pressure at ambient temperature could be estimated. From the measured values, the vapour pressure of the test item DIMETHYLSULFOXIDE D6 was calculated as 92 Pa at 20.0 °C and 116 Pa at 25 °C. The values of the heating and cooling down phase showed good correspondence. Therefore, the result of the study is considered valid.
