Applicant's summary and conclusion

Conclusions:
The vapour pressures of the test item Tecnoflon BA 104 cannot be interpolated and extrapolated for the temperatures 20, 25 and 50 °C, according to Regulation EC No. 440/2008 Method A.4. Vapour Pressure and OECD Test Guideline 104 (2006). The vapour pressure can only be estimated to be below the detection limit of the apparatus:
Temperature / °C Vapour pressure / Pa
20 <10-3
25 <10-3
50 <10-3
