*System instability. The (In) p values obtained during this measurement were not used for the calculations.
The Static Technique was used for the determination of the vapour pressure at 20°C.
At the beginning of the test the vapour pressure of the test substance decreased slightly every next measurement, due to the removal of volatile impurities. After measurement 35 this decrease became negligible and the vapour pressure became stable. So from that moment on, the collected data were used for the determination of the vapour pressure of HatcoI 3344.
