- Conclusions:
- The limit value for the vapour pressure of test item SP02 (trade name: 50HMIC) is 1.3x10^-7 Pa at 20 Celsius calculated by the Grain-Watson method, using a lower limit value for the boling point of 684 K (411 Celsius) for SP02 based on three different calculation methods.
- Executive summary:
The calculated limit value for the vapour pressure of test item SP02 (trade name: 50HMIC) is 1.3x10^-7 Pa at 20 Celsius as based on the Grain-Watson method, a lower limit value for the boling point of 684 K has been used that is based on three different calculation methods for the boling point (Yalkwski, Joback, and Joback-Stein).
