If more than one reference is given for a substance, the first reference refers to the equation currently used in FluidCal. In a few cases, there is a more recent equation of state given in second position, which unfortunately has not been published to date. These equations as well as missing (see the example at the end of this section) or upcoming fundamental equations of state and the most recent transport equation partly contained in the second reference can be integrated into FluidCal on request.
