Applicant's summary and conclusion

Conclusions:
The vapour pressure of the test substance at 20C was <8.40*10 -7PA = <6.30*10 -9mmHg.
Executive summary:

The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of the test substance. The vapour pressure of the test substance at 20C was <8.40*10 -7PA = <6.30*10 -9mmHg.
