Applicant's summary and conclusion

Conclusions:
The vapour pressure at 20°C was calculated from the average headspace concentration.

The result was 4.66X10^2 Pa.

Therefore:

Vapour pressure of the test item: 4.66X10^2 Pa at 20°C
Executive summary:

The vapour pressure of the test material TBPK has been determined to be 4.66x10^2 Pa at 20°C using the Gas saturation method.

Therefore:

Vapour pressure of TBPK: 4.66x10^2 Pa at 20°C;
