Applicant's summary and conclusion

Conclusions:
For the test item Fatty Acids, vegetable-oil, Me-Esters, sulfurized, the following vapour pressures at 20 °C and at 25 °C were calculated for a molecular weight of 300 g/mol from the regression equation:
Vapour pressure at 20 °C: 9.68 * 10-07 kPa
Vapour pressure at 25 °C: 1.75 * 10-06 kPa

For the test item Fatty Acids, vegetable-oil, Me-Esters, sulfurized, the following vapour pressures at 20 °C and at 25 °C were calculated for a molecular weight of 1100 g/mol from the regression equation:
Vapour pressure at 20°C: 5.05 * 10^-07 kPa
Vapour pressure at 25°C: 9.16 * 10^-07 kPa
