Applicant's summary and conclusion

Conclusions:
Vapour pressure measurements were taken using a MKS Baratron Capacitance Manometer (no GLP) on the registered substance itself. The test procedure is in accordance with national standard methods with acceptable restrictions and therefore reliability of Klimisch 2 has been assigned. Vapour pressure: 11.7 mm Hg at 21.1°C and 35 mm Hg at 50°C
Executive summary:

Vapour pressure measurements were taken using a MKS Baratron Capacitance Manometer:

Sample   VP at 10°C (mm Hg)  VP at 21.1°C (mm Hg)  VP at 50°C (mm Hg)  VP at 80°C (mm Hg)
 20190404B  6.4  11.7  35.0  43.7 *

* The reading at 80°C was unstable – this may be caused by the temperature being near the melting point.
